Mystic strapless white dress with black lace

Strapless white dress with black lace and ribbon belt, zipper in back. It's similar to the "Storied Romance Dress in Snow" from Modcloth, except this one has the belt attached in the front. Unfortunately the part of the tag that said the size has been cut off (it was like this when I bought it), but to the best of my knowledge the size is an M.
