Sorry, the only image of Blair in this dress was this and the face got cut of when I uploaded it here no matter what I did. Anyway, I think Serena looked better and her dress was prettier too.

I think in this episode they deliberately make serena look better !! because she was like having yale and everything from blair ..and all of that was just a dream !!!so no need for comparision here !!!!! because they wanted serena to be the "it" girl while blair suffering ... end of story

I accidentally speled Fair as Far. Sorry.

In a later episode you see Blair in this same costume and she look amazing. Leighton just looks more the part, I mean she even pulls of look amazing in the rags.
