I purchased this, but didn't check the size, and it was too big, so I'm selling it after only trying it on. It looked like it hadn't been worn much at all. There's no particular brand, but the mesh material from the décolletage to the sleeves is sheer, which I think is very stylish. It didn't seem to be a very tight fit. The bust and décolletage have a heart-shaped cutout, which is very cute. I am a non-smoker and I don't have any pets!!
