Charli & Dixie D’Amelio and Hollister: The Birth of a Denim Phenomenon

In the summer of 2020, Hollister set out to redefine jeans for the next generation. Their ambitious mission: to make Hollister the premiere denim destination for teens during the pivotal back-to-school season. Through the strategic recruitment of charismatic TikTok stars Charli and Dixie D’Amelio, alongside science personality Bill Nye, the brand forged an innovative campaign—the Hollister Jeans Lab—that merged style, authenticity, and social media prowess.

Understanding Gen Z: The Heart of the Campaign

The campaign’s success hinged on deep insights into Gen Z’s shopping behavior:

  • Shopping for confidence: Teens seek more than just clothing; they want to feel confident in their look and expression.
  • The emotional fit test: For this generation, finding the right jeans is an emotional and physical journey—most teens perform “fit tests” to ensure comfort, durability, and style.
  • Brand loyalty starts at denim: Many young shoppers discover Hollister through denim. When they connect with the jeans, they become long-term customers.

Launching Amid Turbulence: Pandemic Pivot

Originally planned as an expansive in-person retail campaign, the Hollister Jeans Lab had to quickly evolve due to the onset of COVID-19. Lockdowns and school closures dramatically changed the back-to-school season, pushing brands like Hollister to seek innovative engagement strategies tailored to a global audience now confined at home.

In response, Hollister transformed its campaign into a fully digital, 360-degree experience anchored in the platforms Gen Z dominates—especially TikTok and Zoom. This virtual shift not only preserved the campaign’s relevance but also provided a blueprint for other brands navigating the new normal.

The Virtual Denim Lab: Science Meets Style

The campaign’s creative centerpiece was the virtual “Denim Lab.” Here’s how it came alive:

  • Bill Nye as Chief Jeanealogist Officer: Iconic science educator Bill Nye led the scientific angle of the campaign, testing Hollister jeans for real-world performance—eliminating waist gaps, ensuring stretch retention, combating pocket bunching, and resisting fading.
  • Charli and Dixie as Jeanealogists: The D’Amelio sisters partnered directly with Bill Nye, subjecting jeans to the ultimate test—dance. Their signature routines, energy, and relatability made denim trials accessible and entertaining.

The #MoreHappyDenimDance TikTok Challenge

TikTok’s status as the epicenter of Gen Z trends made it the ideal stage. The #MoreHappyDenimDance challenge, choreographed by Charli D’Amelio herself, served as the campaign’s viral catalyst.

  • Choreography and custom soundtrack: Charli created a fun, high-energy routine set to a custom Hollister track, encouraging fans to participate in their own “happy dances.”
  • Contest and engagement: Participants using #MoreHappyDenimDance—and for some phases, #HCoContest—could win a virtual meet-and-greet with Charli and Dixie, sparking a frenzy of entries and user-generated content.

Impact on TikTok

The #MoreHappyDenimDance challenge exploded in popularity, with:

  • Billions of hashtag views within the first week alone
  • Thousands of teens submitting their versions of the “happy dance” across social channels
  • Massive increases in brand exposure and direct engagement with the D’Amelios

This campaign not only showcased how TikTok could drive direct retail outcomes but also highlighted Charli and Dixie as icons of digital youth culture.

Jeans Tested by Science: What Sets Hollister Apart?

One of the most distinctive elements of the campaign was its commitment to scientific rigor—albeit with a playful edge. Bill Nye and the D’Amelios put Hollister denim through the following tests:

  • Stretch retention: Jeans were tested for their ability to maintain shape after movement and washing.
  • Waist gap solution: Special attention was paid to eliminating awkward waist gapping, a common complaint in denim fit.
  • Pocket bunching and fading resistance: The lab tested for annoying pocket bunching and premature fading, ensuring jeans looked and felt fresh longer.

The results blended credibility (with Nye’s scientific seal of approval) and entertainment (with the D’Amelios’ dance routines)—a dual approach few brands had executed at such scale.

Personalized Style: Charli and Dixie’s Favorite Hollister Jeans

The campaign didn’t just rely on celebrity power; it offered a tangible connection through product. Charli and Dixie curated their own signature picks from Hollister’s jeans collection, each tagged for easy identification online and in stores.

Highlights of their curated collection included:

  • Skinny jeans with stretch: Designed for dance and daily comfort
  • High-rise mom jeans: Combining retro style with a Gen Z twist
  • Classic straight leg: Versatile and easy to style

Fans could instantly shop the D’Amelios’ looks, escalating sales and blurring the line between influencer endorsement and product design.

Exclusive Drops and Fan Access

To drive urgency and community, Hollister launched a limited-edition capsule collection co-designed with Charli and Dixie. Available first to fans and loyalty members, the pieces featured personal touches—think signature embroidery and special tags—turning everyday denim into coveted collector’s items.

Building Brand Love: A Long-Term Strategy

What began as a back-to-school push soon evolved into a lasting relationship. The campaign continued into the holiday season, with additional content releases, shopping events, and digital activations starring the D’Amelio sisters. Their consistent involvement fostered authenticity, a critical value for Gen Z consumers wary of superficial celebrity endorsements.

Social Media Synergy: Beyond TikTok

Though TikTok served as campaign headquarters, Hollister strategically expanded across:

  • Instagram and YouTube: Behind-the-scenes footage, Q&As, and styling tips
  • Zoom live events: Real-time denim try-ons, audience Q&A, and exclusive promo codes
  • In-store displays and digital signage: Bringing the digital energy into physical retail spaces for those able to shop in person
