About Last Night: Sienna Miller's Striped Celine on Jimmy Fallon

Who: Actress Sienna Miller

Where: The Tonight Show with Jimmy Fallon, New York City

Why: Despite the fact that Sienna Miller has been almost unrecognizable in her Plain Jane-type roles in American Sniper and Foxcatcher (dark brown hair, sensible cardigans, baby bump), she’s going full glam for awards season. The actress made a Miu Miu frock look downright sexy at the Golden Globes on Sunday night, and then for her appearance on Jimmy Fallon on Tuesday, she kept it simple and chic in a fiesta-style striped Celiné dress. Accessorizing it with strappy black heels, minimal jewelry, and a choppy, blond bob, Miller made a knit sweater dress look high fashion. Move over, Kate Moss. Miller is the current queen of British boho style.
