Under armour black compression wireless bra *size estimate *missing tag

Please note this bra does not have a size tag and In am making a best guess on its size. I believe it is a size medium when comparing it to other wireless sport bras and based on how it fits my mannequin. It is in good used condition with strong elasticity and no rips, holes, or other imperfections. The only flaw is it’s missing size tag.
