The Serpentine Summer Party — a staple on the British social calendar — returned on Tuesday evening to Kensington Gardens. The famous fête, which raises funds for the Serpentine’s artistic programing, welcomed Cate Blanchett as a co-host this year. The result? A starry gathering of boldface names from the worlds of fashion, art, and philanthropy.
For the outing, the Oscar-winning Australian actor chose to spotlight the buzzy London-based Turkish designer Dilara Findikoglu. Blanchett, no stranger to an avant garde style statement, opted for a oceanic-inspired sculpted breastplate top adorned with peals and seashells from the Fall/Winter 2025 collection, which she paired with a fluted hem skirt.
This year’s installment of the annual upscale affair celebrated the 2025 Serpentine Architecture Pavilion, designed by Bangladeshi architect Marina Tabassum. For the first time ever, the Serpentine also enlisted a Host Committee, chaired by Indian arts patron Isha Ambani to oversee the ambitious fundraising goals. The inaugural committee members included singer Joy Crookes, The Morning Show actor Gugu Mbatha-Raw, and many other influential names in art and design.
As is tradition, key players in the London fashion scene were also invited to attend — many with their muses of choice wearing their pieces. Among the guest list were Alexander McQueen’s Seán McGirr, Burberry’s Daniel Lee, Rabanne’s Julien Dossena, Self-Portrait’s Han Cong, 16Arlington’s Marco Capaldo, David Koma, Harris Reed, Rejina Pyo, and Sir Paul Smith. Additionally, rising talents like Charles Jeffrey, Conner Ives, and Chet Lo were also spotted in the crowd.
