Abstract: A shirt (10) or upper cover comprises a torso enclosure (14) and sleeves (16, 18). The sleeves (16, 18) have short top lengths (TL) and long bottom lengths (BL). The sleeve seams (20, 22) extend over the clavicle/acromin regions of the wearer (12) of the shirt (10). Top regions (30, 32) of the torso enclosure (14) and the tops (34, 36) of the sleeves (16, 18) follow the curvature of the shoulder substantially above the shoulder joints. The bottoms of the sleeves fold upwardly into the armpits of the wearer (12), providing perspiration absorbing cloth against skin regions of the torso and the arms.
