This Anthro Tube Top is faux patent leather. It is stretchy due to the mesh in the back but does have a side zipper to make it easier to get in and out of. This is most definitely an XL. This will best fit a C cup or bigger best as the bust area has a lot of room. If you'd like measurements please don't hesitate to ask! I'd be happy to provide them! Don't like my price? Feel free to make an offer! Reasonable offers will be considered!
