I love all of out of print's shirts, they've consistently been a good product for me and most of my favorite shirts come from them. That being said, this particular one was a bit of a let down. Normally their lighter shirts are great and and not see through at all, but this one was very sheer...It's not that bad, I've seen worse, but you will definitely need a nude bra with it and I'd recommend ordering a size up because I think if mine was tighter it would be verging into can't-wear-in-public territory. As it is, I mostly use it to layer with, and it works well on cloudy days. I'm not saying it's unwearable, just be warned that it is pretty sheer.

As far as sizing, I would generally say order a size up anyway because they usually run small, and if you don't mind it being a tad flowey I'd say go two sizes up with this one. I'm 5'9, about 140 pounds, and a D-cup (medium in most shirts), and I got the extra large and then shrunk it in the dryer and it fits perfectly, if that's helpful at all.
