Reebok Racer Back Tank

Reposhing Reebok Tank that arrived 10/27. It is gray/white with a coral/pinkish stripe down the back. Has reflective Reebok logo on upper chest near strap. The size is worn off on the inside but when I purchased it was listed as Medium. I laundered and hung to dry but have not worn. I’d say it’s a slim fit M and would work as a loose top for a Small or comfortable fit for Medium.
