Last night, Rihanna wore her fanciest bathrobe yet and palled around with fellow-Moschino clad friends Katy Perry, Miley Cyrus, and Jeremy Scott at the Daily Front Row’s Los Angeles Fashion Awards, where attendees included everyone from Kanye West and Gigi Hadid to Drew Barrymore and Kerry Washington. Meanwhile, across town, Alexa Chung threw a launch party for her AG capsule with Gia Coppola and Amanda de Cadenet Taylor, and in New York, Questlove was the DJ for a party at Up & Down. In Berlin, Katie Holmes wore a fedora to a celebratory Marc Cain dinner, and back in New York, Anne Hathaway kept it casual in Stan Smiths at the after-party for the premiere of Song One. The American Ballet Theatre celebrated its 75th anniversary with Misty Copeland, and the Museum of the Moving Image threw a party in honor of Julianne Moore.
