I'm being a post whore tonight: Help me shop!

[joshlyman]

I need a white dress for a bachelorette. Going to bars in Santa Barbara, so nothing super fancy, but not sundress casual either. Preferably under $100. Not too short (not looking to give a show). I've lost almost 50lbs now, so something a little figure showy would be nice, although I al still a size 10.

I am having the hardest time finding something I like. Here is a pic so you can see body type (I've got the pony - my sister is the cute one with the funky hair): Help!
