Lulu’s black lace dress

Size medium (but to me fits more like a small) NWT black long sleeves lace dress. Tried on once and hung up in my closet. Purchased from Lulu’s and the arms fit a bit tighter than I’d like but I’ve also lost quite a bit of weight and think it might be my loose skin causing the issue. It is so cute on and a great length. Not too short! Would be perfect for a fall or winter wedding. Thanks for looking!
