NWT Anthropologie Maeve Cap Sleeve Cut-In Floral Tank Top

New with tags Anthropologie Maeve. Has spandex type material, very stretchy and flattering. I have this in another color and was excited to get this. I just opened the box and they sent the wrong size-I waited too long to open it and can’t file a return claim. I’m SO bummed! I’d be happy to trade for a medium, or sell. My lens has a shadow dot, there is nothing wrong with top!
