Very lightly worn, maybe 2-3x. There are no stains or signs of wear. It has a lined built in bra, with vented sides. Very form fitting and comfortable. I love the back straps. It is a size Medium and with most Nike I find their tops run small I am an xs/s in other tops this one being a medium is really only big on me in the breast area (I would say it would say a full C would fill it.)
