I normally don’t see much harm in two celebrities wearing the same dress, but when the dress is Chanel, the first wearer is Blake Lively, and the setting is Chanel’s Spring 2011 show, one can’t help but wonder what Chanel’s PR department was thinking when they let Alexa Chung wear it earlier today.

While Lively paired hers with nude Louboutin pumps and a summery ponytail, Chung opted for flat loafers and her signature disheveled bob.

Who do you think wore it better?

(My vote is neither. I actually hate the dress, and both girls look a mess in it)
