Aeropostale Top with Fun Quirky Back

Light gray Aeropostale top with a semi-open(??) back, pretty sure it's meant to be worn over a cami/tank top or something I think it's also supposed to be a crop top, but either I have a short torso or it's just weirdly in between a crop top and a normal length shirt 60% Cotton, 40% Polyester Chest ~18" Flat
