This short sleeve knit T-shirt creates a loose silhouette and makes it easy to move around or relax. But the key point is its breast pocket. It's made from a cotton blend that has just the right amount of stiffness and enough thickness that it doesn't lose its shape. Not only is it comfortable in summer, but it's easy to wash as well. The collar, sleeves, and hem conceal a second color that is revealed when you roll up the sleeves or take the cardigan off, adding a subtle accent to your overall look.
