These Athletic Polos are designed to be very fitted and move with the athlete. If you are uncomfortable with a fitted silhouette, consider sizing up. If you are in doubt... size up.
Great, comfortable shirt
Love this shirt! Great quality. The venting in the underarm is very comfortable and cooling. Looks great too. I have two, one short sleeve and one long. I am "busty" and had to go up a size from my normal.
