Women's Flowy tank

This is a unique top. Pink, white and black. Tie-dyed. Has size pockets. The back has a oval shaped cut out at the base of your neck. Two layers as the top layer has a slot down the middle that opens to the second layer. Tried to show in the pictures. Size listed is "one size". 🤦🏼‍♀️I would say it's close to an XL. 🤷🏼‍♀️
