Fashionista, Mary-Kate Olsen, looked super-chic @ the Met's 125th Anniversary Gala (hosted by Yves Saint Laurent). Dressed in a frock from YSL pre-fall '09, MK looked effortlessly fly. I loved the silver crocodile bag/belt ensemble. Also, the red polish and lipstick add a superb pop of color. As you know, its all about the details. MK definitely didn't disappoint. Love it!
