Eiza González joined a bevy of high-profile guests for the 2025 Serpentine Gallery Summer Party in London on Tuesday. The event, cohosted by actress Cate Blanchett, celebrated the 25th anniversary of the Serpentine Pavilion in Kensington Gardens, designed by Bangladeshi architect Marina Tabassum this year.

For the special summertime fete, González opted for a sheer dress courtesy of Harris Reed‘s fall 2025 ready-to-wear collection. The bias silk gown featured a high neckline and angular short sleeves with sheer black fabric on the bodice and skirt. The silhouette featured a formfitting style, with the skirt flowing slightly from the knees. Running down the bodice and skirt of the dress in sinuous style were hand-painted pieces of gilded gold, adding color contrast and a provocative element to the ensemble.

Reed took to Instagram to share photos from the event, thanking stylist Elizabeth Saltzman “for the support and love from day one.” Saltzman regularly collaborates with González on her red carpet and special occasion attire. The stylist has also worked with Elizabeth Debicki, Saoirse Ronan and Julia Garner, among others. González’s hair was styled by Dayaruci with makeup by Francesca Abrahamovitch.

Reed’s fall 2025 ready-to-wear collection made its debut as part of London Fashion Week in February 2025. “The British American designer toned down his usual palette of jewel tones to focus on black and gold with flecks of red, green or blue in the embroidery details of some pieces,” Hikmat Mohammed wrote in WWD’s review of the collection.

“The world is in a tough spot right now and especially the creative [spaces]. So for me, I really used that as fuel to come out with pieces that were really about putting the internal on the external,” Reed said of his designs for the fall 2025 ready-to-wear collection.

Highlights from the collection included moments of minimalism contrasted by “points of exaggeration — a gigantic wrap-around hoop skirt with a bralette that had antennas; a tailored bomber jacket with cutouts at the breast revealing little embroidered flowers, and a perfectly constructed cage dress that was a highlight of an uneven collection.”

The 2025 Serpentine Gallery Summer Party was held on Tuesday at the Serpentine Pavilion in London, cohosted by Cate Blanchett. Lily Allen, Georgia May Jagger, Rebecca Vallance, Kelly Osbourne, Harris Reed, Lady Amelia and Lady Eliza Spencer were among the attendees.
