A perfect work out shirt, or for just wearing on chillaxing days around the house. I purchased this in the XL, my bust is 36D, waist is 29. It’s very loose and because of that, it’s perfect for comfort, but not too flattering. If I were going to get another for actually going to an exercise class, I would get a smaller size. I purchased the black, and it’s still pretty sheer. I would wear a tank underneath, but someone a bit smaller than me could pull off a cute sports bra. It would also look adorable tied up with a little knot at the side.
