That wasn’t the only Stella McCartney look Williams wore at Paramore’s Wembley Stadium show. She also suited up in the designer’s purple triangle-bra halterneck dress from the fall 2022 collection to join Taylor Swift on stage for a surprise duet of their 2023 collaboration “Castles Crumbling.”

Stella McCartney has debuted a new ‘it’ bag at Paris Fashion Week – stealing the spotlight from the current buzzy accessory, The Row’s Margaux bag. The new ‘quiet luxury’ it bag was presented in varying sizes – from micro minis to large weekenders.

The showing gathered a slew of top stars including Jameela Jamil, Olivia Palermo, Cole Sprouse, Barbara Palvin, Anna Wintour, Rob Lowe, Paris Jackson and Hayley Williams, and more.
