I wore this dress to prom and was really happy with it. The material was nice and it fit well. My only problem with it is that the built in slip is a little shorter than the external chiffon so the extra fabric looked odd. I ordered up a size because I didn't want it to be tight around the bust. For those of you in the same boat, I'd say order up, but beware that the dress might be a bit bigger everywhere else. Anyone else, order the size you usually wear. Oh and the sash tie is a great addition, it gives the relatively shapeless dress a nice, personalized form.
