That's our girl! Mary Kate Olsen vamped it up at the Metropolitan Opera's 125th Anniversary Gala yesterday. While MKO and her sister Ashley are normally only lauded by hardcore fashionistas, mainstream media has been loving on this look for her.

She wore a Yves Saint Laurent dress and YSL clutch as well. Mary Kate completed the look with the perfect shade of red lipstick and major curls.

Yes, she's pale, yes, she looks like she could possibly be auditioning for a spot in the next Twilight film (how awesome would that be?), but the style works for her. MKO has never been one to follow the typical faux-bronze, faux-boobs crowd -- and that's why we love her!
