Celebrities caught in the same Marc Jacobs dress

I'm sure many of you were experts in identifying this Marc Jacobs Resort 2011 Floral Embroidery dress. There were tons of tips sent to me via formspring on the dress, thank you.

September 13, 2010 - Leighton Meester at V Magazine New York Issue Party.

November 9, 2010 - Gigi Leung (梁咏琪) at her Beijing Concert Press Conference.

December 31, 2010 - IU (아이유) at MBC Gayo Daejun.

January 27, 2011 - Kim Tae Hee (김태희) in MBC Drama, My Princess episode 7.

My choice stays firm with Leighton Meester being the best dressed among them. I would have given it to Kim Tae Hee (김태희) because of her personality in the drama if not for those shoes.
