Boohoo NEW Gray Millie Mock Neck bodycon long sleeve mini dress sz Small

Boohoo NEW Gray Millie Mock Neck bodycon long sleeve mini dress. Size label says that its a size 10, but I wear a small to medium and am wearing it in the photos. It fits like a small, so I'm listing the size according to the actual fit. Unlined. Stretchy. I'm 5.5" for height reference.
