Which dress should I wear?

[drunkontea]

Shei, the magazine I'm on (aka what I slave over), has gone to print and delivers tomorrow! The magazine launch party is Saturday and I bought the following dresses. Dress code is, well, "dress to impress." I don't know if the first is too casual or if the second is too business. Which should I wear??

PS. Here are craptacular photos of me in each (respective) dress.
