I was on the Vogue site today and thought I’d share to you this picture I’ve found of a woman dressed in the sexiest blue dress I’ve seen in years. Can you guess who she is?

Margiela dress with a Derek Lam belt and Christian Louboutin shoes

She’s an it girl, and her name is Katharina Harf. And she’s not your ordinary girl on the street. She is the co-founder and executive vice president of DKMS Americas, an organization that hosts the largest bone-marrow-donor center in the world. Isn’t she simply fabulous?

She’s perfect in almost every aspect (except for the fact that a teeny part of her dark-colored bra showed in the picture). My gosh, I wish I was as sexy as that. She obviously has excellent taste in fashion. And it doesn’t hurt either that she has a designer for a husband, Marc Jordan (Rihanna’s manager).
