Lullemon Athletica grey/white wide strap shelf bra tank. Size US 6

I sometimes feel a little exposed in the little strappy bra tanks so this one gave more coverage and held me in a bit more! The shelf bra tank has openings to insert a bra cup as an option, but did not come with the cups. Very gently worn, in great condition. No fabric content but my guess is a polyester/spandex mix. It has a lot of stretch. No care tags but I washed on a delicate cycle and hung to dry with no problems. Not absolutely sure about size but I’m guessing a US 6
