XS BOOST Size S/M Black Tank Top Like New Condition .Stretch Top

I have two of these fun little tops. Comfortable 65% cotton and 30 % polyester, 5% spandex. Pit to pit measures 17 in. The material is stretchy so that could vary a little. They are in Black with textured fabric (See Photo) They have never been worn although there are no tags on them. So consider them preowned but in excellent condition. They are both S / M in size probably listed that way due to spandex in fabric. They have some flexibility in the shape and size..
