Monthly BVI score by brand across the full reporting window, each month normalized to 100 within the 6-brand set using the same method as the ranking below. Hover the chart to compare all six brands within a given month.
BVI = 25% (earned + owned) posts volume · 25% (earned + owned) engagement volume · 25% average owned follower volume · 25% average Google search index — each metric normalized to 100 within the 6-brand set, then combined 25% each. MoM % vs March 2026, on the same method.
Top hashtags, co-mentioned brands, and product/topic themes mined from Instagram & TikTok posts published in April 2026 for each brand (earned + owned).
Conversation is dominated by the brand's own Milan Design Week / Salone del Mobile home-collection launch (four of the month's top five posts, 2–2.5M engagement each). Secondary volume comes from the enduring "old money" / Ivy League prep aesthetic trend, largely earned styling content. Co-mentioned most with Gucci, YSL, Louis Vuitton, Qeelin and Boucheron — mostly multi-brand roundup/editorial posts, not collabs.
Two clear threads: (1) fragrance — Euphoria Elixirs UGC (#fragrancetok, #perfumetok) drove the single highest-engagement posts of any brand this month (up to 27M engagement per TikTok); (2) a '90s nostalgia wave — Carolyn Bessette / JFK Jr. references riding alongside Hailey Bieber's archive-dress moment. Co-mentioned with YSL, Gucci, Tiffany & Co., Ulta Beauty and Macy's.
Volume is overwhelmingly bag-focused creator/affiliate content tagged #coachpartner and #coachny (TikTok Shop affiliate program) — the month's top two Coach posts each topped 15–24M engagement, both affiliate hauls, not brand-produced. Co-mentioned with Aritzia, Princess Polly, Rhode and Anthropologie in "get ready with me" / bag comparison content.
Genuine brand conversation centers on the "For Successful Living" campaign line and regional store activity (Singapore, Osaka). See caveat below — a large share of raw "Diesel" volume this month is unrelated diesel-fuel commentary.
Data caveat: the month's top 5 "Diesel" posts by engagement are almost entirely diesel fuel content — Malaysian fuel-subsidy news, German petrol-price commentary (#tanken, #benzin, #spritpreise), and a Shell Rotella motor-oil ad — a brand-name collision, not fashion-brand conversation. Diesel's BVI posts/engagement volume should be read with this dilution in mind.
The dominant thread is the "The Devil Wears Prada 2" press-tour halo — GRWM and lookalike content referencing the film outpaces owned-campaign content this month. MK's own creator programs (#mkpartner, #mkadvocates) supply a steady secondary volume. Co-mentioned with Gucci, Louis Vuitton and Primark.
Conversation is led by Southeast Asian ambassador activity — Phuwin Tangsakyuen's Malaysia pop-up appearance drove a dedicated regional hashtag cluster — alongside Jisoo (BLACKPINK) as global ambassador. A resurfaced 2024 Met Gala moment (Stray Kids in custom Tommy Hilfiger) also went newly viral this month via a GQ Italia throwback post.
Named campaigns and ambassador activity confirmed via press and brand coverage that explain the topic signals above.
Ralph Lauren presented its Fall 2026 Home Collection at Salone del Mobile during Milan Design Week, introducing the Saddlebrook and Sterling Square collections and opening its first Home store in Milan. For the first time at the fair, models moved through the brand's Milan palazzo in Women's Collection and Purple Label menswear, tying fashion to the home presentation. Guests including Mindy Kaling and Derek Blasberg appeared in brand content from the event.
Euphoria Elixirs, a new parfum-intense fragrance collection, launched fronted by Rosalía — the campaign (shot by Carlijn Jacobs) is the direct source of April's #fragrancetok/#perfumetok creator surge. Separately, Hailey Bieber wore a custom Calvin Klein dress built from the brand's Spring/Summer 1992 archive to the 2026 TIME100 Gala, fueling the '90s-nostalgia hashtag cluster. Thai actress Tu Tontawan also fronts the Calvin Klein Collection Spring 2026 campaign (by Veronica Leoni) regionally.
Coach's Spring 2026 campaign, "Explore Your Story," features returning ambassadors Elle Fanning, Storm Reid, (G)I-DLE's Soyeon and Lilas, an expanded role for Paige Bueckers, and newcomer Shan Yichun — built around the brand's "Courage to Be Real" purpose. Running in parallel and independent of the paid campaign, a large wave of TikTok Shop affiliate/creator bag content (tagged #coachpartner) is driving the bulk of April's raw engagement volume.
Diesel's Spring/Summer 2026 campaign continues the "For Successful Living" manifesto (creative director Glenn Martens, art director Christopher Simmonds, photographer Mark Peckmezian), styled against surreal AI-generated backdrops. A Diesel x Tinder "For Successful Loving" Pride capsule was also confirmed, launching in stores and online May 27 — just after this reporting window, worth watching in the May data.
Michael Kors' Spring/Summer 2026 "Saint-Tropez" campaign, fronted by ambassadors Suki Waterhouse and Danny Ramirez (shot by Lachlan Bailey), centers the Hamilton Moderne bag and got extensive Wonderland Magazine coverage in March–April. The bigger earned-media spike came from Anne Hathaway wearing Michael Kors Collection (leopard coat, red dress) to the New York screening of "The Devil Wears Prada 2" on April 29, alongside co-star Emily Blunt.
BLACKPINK's Jisoo is Tommy Hilfiger's global brand ambassador, fronting the brand's summer 2026 "modern prep" campaign. Regionally, Thai T-Wave stars Pond and Phuwin Tangsakyuen lead the Spring 2026 campaign; Phuwin made a dedicated appearance at the brand's Summer Getaway Pop-Up in Malaysia on April 29, generating a concentrated SEA hashtag cluster. A 2024 Met Gala throwback of Stray Kids in custom Tommy Hilfiger also resurfaced virally via a GQ Italia post this month.
