At the amfAR New York Gala To Kick Off Fall 2009 Fashion Week, Rose Byrne, for lack of better wording, completely killed it in this Louis Vuitton dress. It's such a mixture of opposing elements – romantic but fierce; sophisticated but playful; simple but complicated. We'll stop before we go into a tangent. But just know that this dress is it for us!

We also love the makeup for spring. The soft, slightly glossed orangey coral lip is right on trend for spring. Paired with barely there blush and minimal eye makeup, the look is totally crisp and a refreshing change from the bold red lip of last spring.
