High-end fashion, jewelry and watch brands are more aligned with Hollywood A-listers than ever before, as even the smallest red carpet would demonstrate these days. But are stars and the labels they wear doing everything they can to ensure mutual red-carpet success and brand awareness? That’s among the questions The Hollywood Reporter and data firm Launchmetrics will address in an upcoming webinar, “Influence that Performs: The Playbook for High-Performing Ambassador Content,” set for Thursday, Sept. 4 at 11 a.m. EDT.

The Hollywood Reporter and Launchmetrics partnered in December 2023 to produce the Red Carpet Power Rankings series, which kicked off with the 2024 Golden Globe Awards and has continued through the 2025 awards season, including the upcoming Emmy Awards on Sept. 14. Launchmetrics specializes in measuring brand awareness and influence, employing its proprietary Media Impact Value (MIV) algorithm to analyze and rank both brands and stars, spanning five categories in the Power Rankings series: fashion, watches and jewelry, and accessories, as well as the top five women and the top five men at each event. The Launchmetrics MIV algorithm assigns a monetary value to every post, social media interaction and editorial story to determine a brand’s influence and earned engagement.

Via the rankings, for the first time luxury brands and Hollywood stars, their stylists and managers are able to quantify the influence generated by a red-carpet appearance while also enjoying an undeniable transparency in the results. Recent examples include Louis Vuitton’s first-place finish in the fashion category for the 2025 Met Gala, earning $55.2 million in MIV, or Chanel’s number-one finish in the rankings for the 2025 Academy Awards, where the women they dressed included Lupita Nyong’o and Margaret Qualley and earned an MIV of $16.9 million. February’s Grammy Awards, meanwhile, reflected brands that don’t fall squarely in the mainstream, unless they’re worn by the music industry’s most powerful artists, with Jean Paul Gaultier (worn by Chappell Roan) and Vivienne Westwood (worn by Taylor Swift) earning the top two spots in fashion and MIVs of $9 million and $8.9 million, respectively.

But it’s the surprises and unexpected placements that also prove the power of social media and influence when they slide into the Power Rankings — think of the Steph Curry 11 sneakers by Under Armour that Adam Sandler wore to the 2025 Academy Awards, or the Dolly boot, by Brazilian footwear designer Marina Larroudé, that Blue Ivy Carter wore during an onstage appearance with Jay-Z at the 2024 Grammy Awards. Both of those moments vaulted the brands worn into top-five placements for their respective events.

Larroudé will be among the speakers at the Sept. 4 webinar, also joined by IMG Models vice president Mimi Yapor, to cover topics that include the impact of a viral moment on your brand, best practices from both brands and talent to ensure success, defining immediate impact vs. long-term value, and how to choose an ambassador that will be the best fit for your brand and goals. THR contributing writer Laurie Brookins also will share anecdotes that have emerged throughout the two years of producing the Red Carpet Power Rankings, and what lessons can be learned from both what to do and what not to do.
