Formal/Prom order Gown

Product Name: Formal/Prom order Gown
Floor length gown from Windsor. Nude underlining with silver sequence on top. I had it altered to add a thigh high slit on the left side. Size is XS- material is stretchy. This runs bigger than usual. I'm normally an M. The back order has straps that you can tie tight or loose. There is a zipper on the lower back. I purchased for New Years and was not able to wear it. Unfortunately Windsor does not do returns. Dress still has original tags/Never worn. Purchased for $100 from Windsor and paid $35 to add the slit. I am 5"3 and the dress with heels drags in length a little bit on the floor.
