I received this brand new, unused item as a gift, but I'm selling it because I won't be using it. It's a free size, but I usually wear L or XL, so I purchased it as a larger size. It has a lining and is not see-through. It's light and cool to wear. I think it would also look good with leggings. Bust: 79-94 Measurements below are approximate: Shoulder width: 40-41 Total length: 95
