Every Celeb Look From Stella McCartney's Insane Fashion Party in L.A.

Everyone in the fashion industry can agree on one thing: You never turn down a Stella McCartney invite. The British designer knows how to throw a party, so when I got invited to her autumn 2018 presentation in Los Angeles, you can bet I RSVP'd immediately. As it turns out, the bash was even more fun than I could have predicted. None other than Sir Paul McCartney jumped on stage for an impromptu performance, while Leon Bridges, Grimes, St. Vincent, and Beck rounded out the killer on-stage lineup. 

Of course, a Stella McCartney party draws an A-list crowd, so the red carpet was chock-full of celebs like Katy Perry, Kate Hudson, Amber Valletta, Hong Chau, and more. Read on to see the best looks of the night.
