Familiarity: I've used it several times
Fit: Runs small
I love this shirt. I bought it to wear in the winter under shirts and light sweaters so I don't have to wear bulky sweaters all the time to stay warm. It keeps me nice and toasty and I love the lower cut neckline because it doesn't show under most shirts. It does fit a little tight. I usually wear an XS or a S in tops and I bought the S, and it's still pretty form fitting. But that works perfectly for what I wanted to use it for which is an undershirt. I've also worn it 2 - 3 days in a row and the shirt doesn't retain any odors, score!
