NWOT: Milly Lamb Leather mini dress 0

I purchased this dress new with tags from another posher, and took tags off to wear it for first time but it’s too tight on me. While I don’t think it’s been worn, you can see there are some signs of wear, as shown in images. Came in a bag, that it still hangs on 33” shoulder to hem 26” waist Side zip Lamb leather Fully lined
