This is a weird one, because I'm planning to return this top, but have to give it five stars. Unlike many tank tops and muscle tees, this actually fit as expected, in my usual size. No need to size up. The fabric is a thick, good quality, and construction seems good as well. It's even long enough for my oddly long torso. The reason I'm returning it is because it is definitely an undershirt. I'd been hoping I could get away with it as a muscle tee, on its own. Unfortunately, the arm holes are a smidge too large for that, and there is a satin edging on the arm holes and neck that gives it a really feminine, "underwear" type of feel - even in the black. So if you need an undershirt, definitely buy this one.
