Sniff Before You Buy: Deconstructing Billie’s Audacious Armpit Advertising Campaign

In the bustling streets of Manhattan, amidst the cacophony of sounds and a relentless barrage of visual stimuli, a peculiar invitation emerged. Near the high-traffic hub of Penn Station, pedestrians were confronted with giant, stylized armpits adorning billboards. But these weren’t just static images; they beckoned passersby to lean in, scratch, and take a whiff. This provocative Out-of-Home (OOH) activation wasn’t an abstract art installation; it was a meticulously crafted campaign by Billie, the personal care brand known for its norm-challenging ethos, to launch its new Coco Villa deodorant. This wasn’t just advertising; it was an olfactory dare, a sensory disruption designed to cut through the noise. Billie, a brand built on fighting the “Pink Tax” and normalizing female body hair, was once again pushing boundaries, this time inviting New Yorkers to quite literally stop and smell the armpits. This post offers an expert deep-dive into Billie’s audacious armpit campaign. We’ll dissect the multi-layered strategy behind the scent, analyze its execution within the context of evolving OOH and experiential trends, explore its seamless alignment with Billie’s disruptive brand DNA, evaluate its effectiveness through the lens of sensory marketing principles, and discuss the broader implications for advertisers navigating the fiercely competitive modern attention economy.

The Campaign Unpacked: Getting Nostrils-On with Billie

At its core, the campaign was a masterclass in simplicity meeting audacity. Billie deployed massive, armpit-shaped scratch-and-sniff billboards in strategic Manhattan locations, inviting the public to directly sample the fragrance of their new Coco Villa deodorant. It represented a bold, humorous, and refreshingly direct approach to product sampling, transforming a typically mundane advertising medium into an interactive sensory experience.

Execution Details: The What, Where, When, and How

The physical manifestation involved large-scale posters or billboards designed to resemble armpits, equipped with scratch-and-sniff technology. These weren’t tucked away on quiet side streets; they were strategically placed in high-traffic areas to maximize exposure and interaction. Reports specifically mention a trio of these posters near Penn Station, with one precise location identified as 505 8th Avenue. This choice of location is significant – Penn Station guarantees immense foot traffic from a diverse demographic, ensuring the campaign reached a broad audience of commuters, tourists, and locals. The campaign wasn’t permanent; it ran for a limited time, active through Friday, May 16th, creating a sense of urgency and aligning with common experiential marketing tactics that leverage scarcity to drive immediate engagement. The mechanism was straightforward: pedestrians were encouraged to physically approach the billboard, scratch the designated armpit area, and experience the Coco Villa scent firsthand. This direct interaction was the campaign’s unique selling proposition.

The Product in Focus: Coco Villa Deodorant

The star of the show was Billie’s All Day Deodorant in the new “Coco Villa” fragrance. The scent itself is described as a tropical escape – a sweet, bright, and cozy aroma combining notes of spiced vanilla, coconut cream, and sun-kissed sandalwood. The choice of such a pleasant, evocative scent profile was likely deliberate. It creates an appealing contrast with the potentially off-putting visual of an armpit, aiming to replace any negative preconceptions with a positive sensory memory linked directly to the product. Beyond the fragrance, the campaign implicitly promoted the deodorant’s key attributes: it’s part of Billie’s All Day Deodorant line, which is aluminum-free, baking soda-free, dermatologist-tested, and promises up to 24 hours of freshness. It’s also formulated to be lightweight and streak-free, avoiding stains on clothing. These features align perfectly with Billie’s broader brand messaging around “clean ingredients” and creating effective, feel-good body products. The $9 price point also underscores Billie’s original mission to offer affordable alternatives in the personal care space.

Generating Buzz: Virality by Design?

The campaign quickly transcended its physical location, achieving significant viral traction online. Platforms like TikTok and Instagram saw numerous users sharing videos and photos of themselves interacting with the giant armpits, expressing amusement, surprise, and curiosity. One notable TikTok video, captioned “Love the fresh smell of @billie pits in the morning,” garnered substantial engagement, filled with laughing emojis and comments like “This is hilarious and genius”. While one user reportedly questioned the chemicals involved in the scratch-and-sniff mechanism, the overwhelming reaction appeared positive, appreciating the humor and novelty.

This viral spread wasn’t merely a fortunate byproduct; it appears to have been an anticipated, if not engineered, outcome. The campaign’s inherent strangeness and the physical act of scratching a giant public armpit provided perfect fodder for user-generated content (UGC). Such interactions are inherently visual, performative, and shareable – qualities that thrive on social media. By turning pedestrians into participants and potential content creators, Billie effectively leveraged its audience to amplify the campaign’s reach exponentially, demonstrating a keen understanding of social OOH (#sOOH) dynamics. The physical, slightly absurd interaction offered an authentic, relatable moment easily captured and shared, acting as both free advertising and social proof.

Billie’s Brand DNA: The Foundation for Disruption

Understanding why a campaign involving smelling armpits makes strategic sense requires delving into Billie’s core brand identity, which has consistently been built on challenging norms and championing authenticity in the personal care space.

Core Brand Identity & Mission

Billie launched in 2017 with a clear mission: to create a shaving and body care brand specifically focused on women’s needs, rejecting the gimmicks and unrealistic beauty standards prevalent in the category. Founders Georgina Gooley and Jason Bravman identified that women were often overpaying for razors designed for men (the “Pink Tax”) while simultaneously being shamed for having body hair. Billie positioned itself as the antidote, offering quality, affordable products and famously becoming the first women’s razor brand to actually show body hair in its advertising. This commitment to body positivity and normalization became a cornerstone of their identity, with campaigns celebrating “fuzzy pits and happy trails” and emphasizing choice under the banner “Where you do you”.

The brand cultivated a playful, fun, and authentic voice, using bright colors, quirky messaging, and relatable humor that stood in stark contrast to the often aspirational or overly serious tone of competitors. They explicitly rejected the “Venus goddess” archetype often perpetuated by legacy brands. Furthermore, Billie established itself as a values-driven company, taking a strong stance against the Pink Tax, partnering with women-first organizations like Every Mother Counts and YWCA, and maintaining zero tolerance for racism and systemic oppression. This purpose-driven approach has been central to their marketing from the outset.

Target Audience and Marketing Evolution

Billie initially targeted savvy women, likely Millennials and Gen Z, who resonated with their message of affordability, authenticity, body positivity, and progressive values. These consumers appreciate empathy, directness, and brands that challenge the status quo. Starting as a direct-to-consumer (DTC) subscription service, Billie focused heavily on digital campaigns optimized for mobile and social media, aiming to build a community and foster long-term customer relationships.

The brand’s trajectory shifted significantly following its acquisition by Edgewell Personal Care for $310 million in late 2021. This led to a major expansion into omnichannel retail, launching in Walmart in 2022 and eventually reaching over 30,000 stores nationwide, including Target, Walgreens, and CVS. This move necessitated broader brand-building efforts beyond their initial DTC audience, requiring campaigns that could capture attention in the crowded retail environment. Despite this expansion, Billie maintained its disruptive edge, continuing to launch headline-grabbing campaigns like “Project Body Hair,” “Red, White & You Do You,” “Think of a Woman,” and the “10 Things I Hate About Body Care” ad featuring Jameela Jamil.

Contextual Fit: Why Smelling Armpits Makes Sense for Billie

Viewed against this backdrop, the scratch-and-sniff armpit campaign, while unconventional, aligns perfectly with Billie’s established brand playbook. It continues their pattern of using unexpected, slightly taboo-adjacent themes (first body hair, now body scent) to generate conversation and cut through advertising clutter. Traditional deodorant advertising often focuses on preventing odor, masking it, or showcasing idealized, sweat-free individuals enjoying abstract benefits like confidence or attraction. By directly inviting the public to smell an armpit – albeit one scented with pleasant tropical notes – Billie confronts the product’s core function head-on. This directness is consistent with their previous disruptions of category norms, such as showing body hair when competitors wouldn’t. It’s a bold, attention-grabbing tactic inherently tied to the deodorant’s purpose: making underarms smell pleasant.

Moreover, the campaign reinforces Billie’s playful, humorous, and approachable persona. The inherent absurdity of scratching and sniffing a giant armpit billboard injects humor, making the interaction fun and memorable. This contrasts sharply with the often serious, aspirational, or shame-adjacent messaging found in traditional beauty and personal care advertising. The humor lowers the barrier to entry for engagement, making the brand feel more relatable and less prescriptive. It’s not telling people how they should feel or look; it’s inviting them to participate in a slightly silly, sensory experience.

Strategic Analysis: The Scent of Smart Marketing

Billie’s armpit campaign wasn’t just a gimmick; it was a strategically layered execution leveraging powerful marketing principles, from the neuroscience of scent to the evolving landscape of OOH and experiential advertising.

A. The Power of Scent: Olfactory Marketing Takes Center Stage

The campaign’s most distinctive feature was its use of scent, tapping into the potent field of olfactory marketing. Unlike sight and hearing, which are heavily saturated by advertising messages, the sense of smell offers a more direct pathway to emotion and memory. Our olfactory receptors are linked to the limbic system, the part of the brain governing emotion and memory formation. This neurological connection means scents can trigger powerful feelings and associations, often bypassing rational thought. Research suggests around 75% of the emotions we experience daily are influenced by smell.

The effectiveness of leveraging this connection is well-documented. For instance, a study cited by Promodo found that retailer Intersport experienced a 26% increase in football merchandise sales after introducing the scent of freshly cut grass into the relevant store section. Similarly, a Dunkin’ Donuts campaign in Korea used nebulizers on buses to release coffee aroma alongside ads, resulting in a 16% increase in visitor traffic and a 29% rise in sales at stores near bus stops. Pleasant scents can also increase the time consumers spend in a retail environment and foster positive brand associations.

Billie’s application of this principle involved using the appealing “Coco Villa” fragrance – tropical, sweet, and evocative. The strategy was likely twofold: first, to create an immediate positive emotional response upon interaction, and second, to forge a strong, memorable link between that positive feeling, the specific Coco Villa scent, and the Billie brand itself. By choosing a universally pleasant aroma, they aimed to counteract any potential negative association with the “armpit” visual, ensuring the lasting impression was one of tropical delight. This multi-sensory approach, engaging a less-cluttered sensory channel, has a higher potential for creating lasting brand recall and deeper emotional connection compared to a purely visual ad. Research indicates that brands engaging multiple senses tend to be more successful.

B. OOH Innovation: Beyond the Billboard

Billie’s campaign represents a significant departure from traditional OOH advertising. Standard billboards rely on passive viewership and visual impact. Billie transformed the medium into an active, participatory experience, demanding more than just a passing glance. This aligns with several key trends shaping the future of OOH in 2025 and beyond.

Firstly, OOH is recognized for its ability to capture attention. Studies indicate the average OOH ad receives 12 seconds of attention, well above the 2.5-second threshold needed to imprint a long-term memory. Billie’s interactive scratch-and-sniff element likely extended this dwell time significantly, further enhancing recall and impact. Secondly, while the billboards were static, their interactivity mirrors the engagement potential typically associated with Digital OOH (DOOH). DOOH formats are known to drive higher neurological responses and activation rates compared to static OOH. Billie achieved a similar level of engagement through a clever low-tech, high-concept approach.

Thirdly, the campaign effectively blurred the lines between OOH and experiential marketing. It offered a tangible, hands-on brand interaction in a public space, transforming the billboard into a mini-activation site. This aligns with the growing trend of brands creating “tangible experiences as stand-out activations” to cut through digital noise. Finally, the campaign was perfectly primed for social integration (#sOOH). Its novelty and visual appeal made it highly shareable online, amplifying its reach far beyond the physical locations. Placing the activation in an iconic, high-traffic area like Penn Station further increased its potential for social buzz, as research shows placements in landmark locations enhance perceptions of prestige and shareability. This fusion of OOH’s visibility with experiential marketing’s deep engagement and social media’s amplification power demonstrates a sophisticated understanding of modern advertising dynamics. It addressed the core challenge of capturing attention in an over-saturated landscape by creating a multi-sensory, interactive moment worth noticing and sharing.

C. Engineering Engagement & Virality

The campaign’s viral success appears to have been a result of careful strategic design rather than mere luck. Several elements contributed to its inherent shareability. The core concept – smelling a giant armpit – possessed novelty and humor, acting as a powerful “pattern interrupt” that grabbed attention immediately. The physical act of scratching transformed passive viewers into active participants, fostering a stronger sense of connection and making the experience more memorable.

Crucially, the barrier to entry was low. The interaction was simple, quick, and required minimal effort, making it easy for busy pedestrians to engage. This ease of participation, combined with the visually interesting and slightly absurd nature of the act, provided ideal fuel for user-generated content. People could easily capture their interaction on smartphones and share it on platforms like TikTok and Instagram, effectively becoming micro-influencers for the brand. Successful viral marketing often hinges on evoking strong emotions (like humor and surprise), being easily understandable and shareable, involving participation, and having a distinct visual hook. Billie’s campaign incorporated all these elements, suggesting virality was a calculated objective achieved through thoughtful design that leveraged the audience itself to amplify the message.

D. Tackling Taboos & Contrasting with Category Norms

A key aspect of Billie’s strategy has always been its willingness to confront topics typically avoided or sanitized in personal care advertising. This campaign continued that tradition by being remarkably direct about armpits and their scent. Instead of relying on euphemisms or focusing solely on abstract benefits like “confidence” or “24-hour protection,” the campaign put the armpit – visually and sensorially – front and center.

This approach stands in stark contrast to prevailing norms in deodorant advertising. Legacy brands often feature idealized scenarios: athletes performing incredible feats without a bead of sweat, romantic encounters sparked by an alluring fragrance, or models showcasing flawlessly smooth, hairless underarms. Campaigns frequently focus on sweat prevention or the consequences of smelling good (e.g., attracting a partner), rather than the direct sensory experience itself. Examples include Old Spice’s hyper-masculine, often surreal humor, Secret’s focus on female strength and empowerment , and Axe’s long-standing campaigns centered on attracting romantic partners. Even newer, “clean” deodorant brands like Native, while often employing humor, tend to focus on natural ingredients or relatable daily situations rather than such a literal engagement with the body part itself.

By making the armpit the hero of the campaign, Billie effectively subverted these category conventions. This disruption serves to reinforce their brand identity as a challenger – playful, authentic, and unafraid to talk directly about bodies and their functions in a way that resonates with consumers tired of unrealistic portrayals. The following table summarizes these contrasts:

This direct comparison highlights how Billie strategically positioned itself against the grain, using the campaign not just to promote a product, but to make a statement about its unique brand philosophy within the personal care landscape.

Industry Context: Trends, Takeaways, and the Future

Billie’s scratch-and-sniff campaign didn’t occur in a vacuum. It landed squarely at the intersection of several key marketing trends anticipated for 2025, offering valuable lessons for advertisers across industries.

Positioning within 2025 Marketing Trends

The campaign masterfully integrated multiple contemporary strategies. It was a prime example of Experiential Marketing, creating a tangible, memorable brand interaction in the physical world. It tapped into trends like pop-up installations (albeit using existing OOH structures), the power of tangible experiences in a digital world, and the creation of shareable moments. While not deeply personalized, it offered a personal sensory experience, moving beyond generic broadcast messaging towards more individualized engagement, touching upon the spirit of Hyper-personalization.

In the realm of OOH Advertising, it showcased innovation, demonstrating how static placements can become interactive and drive engagement beyond simple impressions. It perfectly embodied the concept of #sOOH, designing a physical activation explicitly for digital amplification. Furthermore, it was a powerful demonstration of Sensory Marketing, leveraging the underutilized sense of smell to forge emotional connections and enhance brand recall. With reports suggesting 63% of consumers desire multisensory engagement from brands, Billie met this demand directly. Finally, the campaign reinforced the growing importance of Authenticity and Purpose. Its success stemmed partly from its alignment with Billie’s established values and track record of challenging norms, resonating with consumers who increasingly favor brands with genuine purpose and transparency.

The Rise of Sensory & Experiential Marketing

The increasing focus on sensory and experiential marketing reflects a broader shift in consumer expectations and the advertising landscape. Visual and auditory channels are incredibly saturated, making it difficult for brands to capture and retain attention. Engaging multiple senses, particularly underutilized ones like smell and touch, offers a pathway to cut through the clutter and create more profound, memorable experiences. Sensory inputs can evoke strong emotional responses and embed brands more deeply in consumers’ minds. Experiential marketing, by its nature, fosters interaction and participation, leading to stronger brand affinity and loyalty compared to passive advertising consumption.

Lessons for Marketers

Billie’s armpit adventure offers several key takeaways for advertisers:

1. Calculated Risks Can Yield High Rewards: Unconventional ideas, when rooted in brand strategy and audience understanding, can generate significant buzz and impact. Billie’s boldness is not random; it’s a core part of their successful brand identity. Don’t shy away from pushing boundaries if it aligns with who you are.
2. Authenticity is Non-Negotiable: The campaign worked because it felt genuinely “Billie.” Ensure marketing activations authentically reflect brand values, personality, and history. Inconsistent or inauthentic attempts at disruption often fall flat or provoke backlash.
3. Integrate Physical and Digital Seamlessly: Design real-world experiences with digital sharing built-in from the start. Leverage physical activations to fuel online conversation and UGC, maximizing reach and impact (#sOOH).
4. Unlock the Power of the Senses: Consider how engaging senses beyond sight and sound could create more memorable and emotionally resonant campaigns. Explore olfactory, tactile, or even gustatory elements where appropriate and brand-relevant.
5. Master Your Context: Understand the established norms and tropes within your category to identify opportunities for meaningful disruption. Know your audience deeply to ensure your message resonates and isn’t just different for difference’s sake.

Ultimately, Billie’s campaign serves as a compelling case study in how to artfully blend OOH innovation, experiential tactics, sensory engagement, social amplification, and brand authenticity into a single, potent activation. It demonstrates a sophisticated grasp of the modern marketing playbook, layering multiple trends to create something far more impactful than the sum of its parts.

A Whiff of Genius?

Billie’s scratch-and-sniff armpit campaign was undeniably audacious. By transforming mundane OOH placements into interactive sensory experiences, the brand leveraged humor, novelty, and the potent power of scent to capture attention in one of the world’s busiest urban landscapes. The strategy was multi-layered: it provided direct product sampling for the Coco Villa deodorant, generated significant viral buzz through social sharing, perfectly aligned with Billie’s disruptive, body-positive brand DNA, and tapped into key marketing principles around sensory engagement and experiential connection.

It stands as a smart, calculated risk that successfully cut through the advertising clutter, reinforced core brand values, and delivered a memorable, if unconventional, product interaction. The campaign’s significance extends beyond just Billie; it serves as a potent example of creative, integrated marketing in an increasingly competitive attention economy. It highlights the potential for brands to innovate within traditional media formats and the growing importance of engaging consumers on multiple sensory levels. The lasting impact will likely be increased awareness for Billie and its Coco Villa scent, but perhaps more importantly, it may inspire other brands to shed their inhibitions and explore more daring, sensory-driven, and experiential approaches to connecting with their audiences.
