I have a Melissa Sweet Noel gown in an unaltered and never worn size 10 (street size is about a 4 or 6) (http://www.priscillaofboston.com/dress_detail.jsp?gid=20&sfid=50907). I bought the gown and love it, but we've decided to have a very low key wedding (or no wedding) and this dress is just too gorgeous to wear to dinner at the local pub.
I bought it at my favorite bridal store in Burlington, VT, where the dress has always lived (it's brand new). My measurements are 33-28-38. The dress is a little big all over, but has lots of room in the bust (I have a very small bust compared to the rest of my body) and a few inches of give in the hips. It's absolutely gorgeous and flattering: it makes my waist/hips look SO tiny, but the dress is all about curves.
The dress sells for $3500-4000 (I have receipts showing how much I paid). I'm asking $2,200 + free shipping. I would sell it via eBay (it's not posted there yet because I don't want to deal with scams), unless you are local.
