Sorella Vita Turquoise One Shoulder Dress

One shoulder cocktail dress. Popular bridesmaid dress. Altered in length to go to my knees (I am 5’2”). Gently used, worn once. See photo where strap partially detached from dress (one thread), could be sewn back on or not needed and thread can be removed. Water spot/stain on back, see last photo. Size 8 but fits like a 2/4 in normal dresses.
