Let this serve as an example of how NOT to rock the exposed lingerie trend this spring.

Blake Lively (who's also been dubbed "Boobs" Lively for her tendency to show cleavage) wore a Carven bubble dress with an exposed corset to the WonderCon 2011 event, which took place recently in San Francisco.

While I can't help but think her dress looked like it was put on backward, and that her chest-centric ensemble fell a little flat (no pun intended), I will give her points for her two-tone Christian Louboutin pump pairing, as they prove the perfect combination of sassy and sweet.
