Enzoani Catherine Best-selling unclassified dresses

I was the Maid of Honor for a wedding that never happened. I'm trying to help my best friend sell her never altered and never worn ivory Enzoani (Catherine) wedding dress. It's a size 10, which measures 37 inches in the bust, 29 inches in the waist, and 40 1/2 inches in the hips. From hem to hallow, it measures 58 inches. My friend is 5'8", and usually wears between sizes 4-6 in her clothing to give you an idea of how this dress compares to sizes usually bought in regular clothing stores. It is a strapless, sleeveless, floor length with a beautiful train, and has some beading and lace. The tag is still on the dress and says purchase price is $1350, but I know after tax and extra costs it was around $1500. It is a very flattering dress!
