Okay, so I like this shirt for the purpose that I bought it for, which is to wear on its own or under t-shirts. It's not really sheer, but it is a very thin and soft fabric, which is fine for me. I've worn it under a vest, a sweater, and to work out in, and it was soft and comfortable in all situations. Also, I am tall and like the shirt too be long, and it is a nice long length. I usually wear a large, and the large I ordered was perfect for me. It is very fitted, which is what I wanted. I liked this shirt so much that I just ordered a few more!
