Purchased a few years ago and worn about 5 times. There is some wear and tear on the fabric from use, but please understand that this is a used item. It's a snug fit, but it's stretchy, so I think it feels like a size S-M. It's thick and not see-through, so it can be worn on its own. I can provide more photos if you'd like. I will ship it out as soon as possible, ideally the same day. Thank you!
