Sheer black dress tank

This loose fitting tank has two layers of sheer black fabric layered over eachother. The inner layer is a normal loose tank top cut while the outer layer parts at the front to give a sheer look in front and more coverage along the chest and back. The back is longer than the front. There is a button loop closure detail on the back. Bought the wrong size, only tried on. Says XXL but looks like it runs small.
