Cocktail Dress

Cocktail/formal dress from Zibi London. Purchased from ASOS. Double lined. Size is UK 16 or EU 44. That comes out to about a size 12 US. The measurements 17 inches across the chest and 33 inches long. Only worn once and I tried to sew in a something to the lining for a better fit (but it didn’t work), so there are small sewing holes in the lining (not visible from the outside).
