BEST DRESSED: KATE BOSWORTH PARTY

more laid-back prettiness than a katy perry song...

Last night at Hemingway's in Los Angeles, Habitual and NYLON teamed up to celebrate the March cover.  That means Kate Bosworth and her flock of It Girls arrived en masse to flutter through DJ Lindsey Luv's songs, and show off their "Oh, we just threw this on at the last minute" outfits.

Below, some highlights from the VIP dinner...  and you get bonus points if you can tell us who made Kate Bosworth's dress.  (Hint: Check the Spring runways!).
