Blake Lively always looks fabulous.

If you've seen any Blake Lively pictures in your life, you can attest. But these two from the Met Costume Institute Gala - 2009 and 2010 style - caught our eye.

Last year, the Gossip Girl cast member donned a gorgeous, teal-blue Versace number that showed off her chest ... and one of her long legs. Not shabby, Blake.

Then earlier this week, she really switched things here in 2010 with a shorter, teal Marchesa number ... showing off both of her legs! Variety is the spice of life.

Suffice it to say, the girl is rather good-looking and we can see Serena in these dresses.

But which gown looked better on the Gossip Girl star if we had to pick? You tell us ...
