Myan NWT Black and White Dress

Myan black and white dress. Racer back, white dress with black edging and design on torso. Flavors at the waist to a skater skirt. Lined and new with tags. I bought it on Poahmark but just by looking at it it is too small for me. Size is a Large but looks like a size 8-10 on a number scale. Has a zippered back.
