The Hollywood Reporter and Bvlgari hosted a celebration for this year's Emmy-nominated and Emmy-winning costume designers at the Chateau Marmont penthouse, held in partnership with the Costume Designers Guild ahead of Monday's primetime Emmys ceremony. The event honoured winners from the Creative Arts Emmys, held on 5–6 September, where five costume design awards were presented across categories including contemporary, fantasy/sci-fi, period and variety programming.

Winning teams from Fallout, The Boys, Love Story: John F. Kennedy Jr. & Carolyn Bessette and Margo's Got Money Troubles attended, alongside prominent industry figures such as two-time Oscar winner Mark Bridges, Hunger Games designer Trish Summerville, Clueless costume designer Mona May and Costume Designers Guild president Terry Gordon. Bvlgari's Brett Fahlgren led a toast praising costume designers' contributions, and the brand displayed its newly redesigned Costume Designers Guild Awards statuette, continuing an event partnership with THR that began with a similar Oscar-season luncheon in March.
