As far as charity galas go, the amfAR Inspiration Galas are always some of the most fashionable events of the season. Thursday's nights amfAR Inspiration Gala in Los Angeles brought out a slew of stylish stars including Sarah Jessica Parker, Kate Hudson and her cleavage, Alessandra Ambrosio, Kristin Davis and Octavia Spencer.

But surprisingly enough, our favorite outfit of the night belonged to none of those A-listers but rather to Rumer Willis. The oldest daughter of Bruce Willis and Demi Moore walked the red carpet in a long-sleeved, semi-sheer top, a prom-like black skirt and strappy platform heels. It was playful, it was tasteful, it was flattering... it just totally worked.

We're also loving Rumer's hair at the moment -- after experimenting with blonde, blue and every color in between, the 24-year-old has settled on a sweet copper ombre.

Seeing as Rumer has had her fashion difficulties, from terrifyingly low necklines to torn-at-the-butt jorts, we're more than happy to see her turn things around. After all, she's got fashion in her blood.

Check out Rumer's outfit from last night -- do you love it as much as we do?

  • Red Carpet Horror From American Horror Story Season 2 Premiere

    The red carpet at last night's American Horror Story season 2 premiere was pretty frightening, and not for any show related reasons (we wish that was the case).
