Sexy Open Back Shirt Pink/ Blush Women Size M, but I think it can fit L -The back of the shirt has a beautiful twisting knot along with a ribbon of fabric at the top to maintain place/ structure. -Fits a medium, but is very flowy so would fit large and extra large. -This is a boutique find that has never been worn. I cut the tags out of the neckline because they were scratchy and then never wore this beautiful daring shirt. -Soft cotton blend/ stretchy material!
