As I have mentioned in previous reviews, the slim-fit is actually a great size from quiksilver as it gives you a more true to size fit without the 'wearing a boy tshirt' look. I purchased a solid black tshirt which can be worn with jeans for a casual occasion, under a jacket for something classier, or shorts to go to a more outdoors activity. Great fit and nice materials makes it a great feeling to wear. If you swim a lot and have a slightly large upper body with a thinner waist, this is the tshirt for you. It won't let you look like you are floating in it.
