There’s a lot to say about what Stella McCartney got up to in London on November 10. During the day, she was previewing her debut menswear collection and her Pre-Spring 2017 womenswear at a Methodist chapel she’d hired just across the street from the Abbey Road Studios, where the Beatles recorded their album of the same name in 1969. She mentioned, in passing, that she was going to have “a party” at the studios later. Turned out, it was more of a mini-Glastonbury of a night, with DJ sets and live performances on two stages from the Beastie Boys, Beth Ditto, Neneh Cherry, Professor Green, Sharleen Spiteri, and more. A very relaxed, very British-music and fashion-friends-and-family affair it was.
