Mischa Barton had a blast during New York Fashion Week. She was front row a many shows, and she also enjoyed hanging out at some of the hippest parties.

One of those parties was the Marc Jacobs after-show-party held at Hiro in New York.

To that party she wore a black embellished Marc Jacobs Fall 2009 mini dress with lace sleeves and a studded wrap-around belt, plus tights and black flats.

Elettra Wiedemann wore the same dress a few day later when she arrived at “The Burning Plain” premiere at Landmark’s Sunshine Cinema in New York.

She wore a pair of sexy strappy sandals, which I preferred to Mischa’s flats.

As much as I want to give this to Elettra, I really don’t like the way the bottom half of the dress hangs down exposing the lace underlay, which as a result gives the look a maternity feel.

So once again I’m giving a win to Mischa by default.

Selma Blair wore a similar one-sleeved version of this dress to the Costume Institute Gala.
