Dress Search.

I am on a search for a dress I could wear on my cousin-in-law's wedding in August. I want to dress down, casual yet a little elegant. These are my top choices from Forever21 but I think I have to look around because I do not really like these 3 that much. Not to mention that I do not have the body to fit in these dresses! Oh yes, I am cramming on my diet routine and hoping to shed off 10 lbs in less than 3 weeks! Goodluck to me.
