The Who What Wear 20th anniversary party brought Hollywood's fashion crowd to the Chateau Marmont on Thursday night, 15 October 2026, and it doubled as a launch: the digital fashion and beauty publication used the occasion to debut its first-ever print issue. Iris Law and Whitney Peak are the cover stars of the special anniversary edition, and both arrived dressed for the moment. Este Haim was on the decks, there was an espresso martini bar on the terrace, and a crowd of actors, musicians, designers and stylists turned up to toast two decades of the site that helped invent shoppable celebrity style. Here is what happened, who was there and why it matters for fashion media.

Who What Wear's first print issue

According to WWD, the party celebrated the debut of Who What Wear's first print issue, a special anniversary edition featuring Iris Law and Whitney Peak on the cover. Copies of the new magazine were displayed across the hotel's penthouse, and guests left with copies of the anniversary issue along with custom-engraved compact mirrors.

For a brand that built its name online, a print edition at 20 is a statement. Print has become a prestige object for digital-first fashion brands: something to collect, photograph and share, rather than the main way readers find the content.

What the cover stars wore

WWD reports that Iris Law arrived in Ludovic de Saint Sernin, the Paris label known for its sensual, body-skimming eveningwear. Whitney Peak wore a colour-blocked look from Lii's spring 2027 collection. In WWD's photographs, Peak's look pairs a pale blue top with a red panel open at the back over a pale blue and black lower half, finished with a red lip and voluminous, side-parted curls. It is a smart cover-star choice: graphic, unexpected and very camera-ready against the party's deep red velvet backdrop.

Inside the Chateau Marmont party

The party was held in the hotel's penthouse. WWD describes guests entering through a black-and-white checkered hallway lined with silver balloons before gathering on the terrace, where Este Haim of the band Haim played a DJ set and a specialty espresso martini bar served drinks all evening. One hotel room was turned into a photo space, and around 9 pm a large birthday cake came out to mark the milestone.

The celebration was held in partnership with Movado and Donna Karan Cashmere Mist.

Who attended the Who What Wear 20th anniversary party?

Who What Wear editor in chief Kat Collings and cofounder Hillary Kerr hosted. WWD lists Owen Thiele, Maddie Ziegler, Benito Skinner, Ashley Tisdale, Cody Simpson, Giveon, Ciara Miller, Olandria, Karla Welch, Sami Miro, Jonathan Simkhai, Katherine Power and Gab Waller among the guests.

WWD's party gallery also captures Shira Haas, Adelaide Kane, Camilla Luddington, Emily Bader, Charlotte Lawrence, Joey Graziadei and Kelsey Anderson, Dylan Efron, Rudy Pankow, Halley Kate and Josh Richards, among others.

The guest list is a neat snapshot of where fashion attention lives in 2026: streaming-series actors, reality TV breakouts, musicians, creators and the stylists who dress them. Karla Welch, for example, is the stylist behind Esmé Creed-Miles's Sense and Sensibility press tour, one of the most closely watched red-carpet runs of the autumn.

The best-dressed moments

From WWD's photographs, a few looks stood out:

Whitney Peak's colour-blocked Lii, the most graphic look of the night.

Olandria in a red-and-black floral corset top and skirt with a sleek black bob, one of the most-shared looks from the party online.

Maddie Ziegler in a brown satin slip dress, photographed in the hotel's vintage-tiled bathroom.

Sami Miro in a black strapless cut-out look against the red velvet.

Owen Thiele and Benito Skinner in coordinated white and yellow leather jackets.

How to steal the party's style

The common thread across the best looks was one strong idea per outfit. Peak used colour-blocking, Olandria used print and a sharp bob, and Ziegler used the sheen of satin. If you are dressing for an evening event this season, pick a single hero, whether that is a bold colour clash, a corset top or a slinky slip, and keep everything else simple: a clean hairstyle, a red or neutral lip and minimal jewellery. It photographs better and feels more confident than piling on trends.

Why Who What Wear matters

WWD notes that Who What Wear was founded in 2006 and was an early player in shoppable fashion media, connecting celebrity style with accessible shopping recommendations. That formula, "who wore what, and where to buy something like it," now shapes how almost every fashion site and social account covers celebrity style. The publication was acquired by Future in 2022, with Kerr continuing to oversee the brand in the US and UK. Katherine Power, who co-founded the site with Kerr, was among the guests.

Twenty years on, the anniversary shows how the model has evolved. The audience still wants celebrity looks and shopping, but the brand is now also leaning into events, partnerships and physical objects like a print issue to build loyalty beyond search and social traffic.
