prom dresses

Just thinking about it is giving me an anxiety attack. I don't know what I'm going to wear, but I hope it's one of the following.

Or

http://www.theoutnet.com/product/22126 But not my size. Fucking perfect otherwise. I can wear it again, casually.

Or

And

Grr. I'm a US 6-8. Any ideas?
