BHLDN Dress

I wore this for my wedding but it could be for a prom, formal occasion, bridesmaid, or another wedding. It is a light mauve/pink color. Illusion neckline, slightly altered for a more petite upper body fit. Size on the tag says 6 but I promise it fits like a 4 (upper body perhaps more like a 2). Please let me know what dimensions or information would be helpful. It was only worn once. Purchased from BHLDN by Anthropologie, brand of the dress is Watters and Watters.
