help me pick out a dress!

[AWJDZ]

ok...I've got a big time wedding coming up. It will be the first time I meet most of the bf's friends who live out of town. The wedding will be the first weekend of April in Spartanburg, SC...7 PM. I can't find anything to wear in my closet so it is the perfect excuse to buy a kick tail dress! The problem is that since it is the first weekend in april (before Easter), in a place I don't know anything about, and a formal (I assume) night time wedding, I can't find a dress and wrap! Some one help me out please! I went to Ann Taylor this weekend, most of their dresses are on a white background (is that ok before Easter?) and sleeveless and the wraps they have are the belero (sp?) types. J Crew has some cute cocktail type dresses...Nordstroms has some cute ones also. Has anyone seen anything else? Any suggestions? All help is appreciated!
