Net-A-Porter are starting to add more Resort 2010 looks to their virtual shelves.

Today they added the stunning Zac Posen crepe jersey gown which Mischa Barton wore to “The Beautiful Life” Launch Party in New York back in September.

It’s a stunning gown. Mischa really did the look justice.

What I loved most about the dress were those beautiful cut-out details on the front and the back.

Check out this gown and many more celebrity looks over at Shop Her Closet.
