A shirt construction includes a pocket that is strategically located and constructed to hold an object, such as a mobile device (e.g., a smart phone). The pocket is a side pocket that is located along one side of the shirt below an armhole thereof such that when the wearer's arm is in a normal lowered position, the upper arm covers and can apply a force to the outside of the side pocket and/or to the object contained in the side pocket, thereby ensuring that the object remains in place within the side pocket.
