A support shirt that provides support through the shoulders and across the chest of a wearer is provided. A gradual curvature or tilt of the sleeves of the support shirt toward the chest of the wearer provides additional support and prevents slack from occurring along the sleeves during weightlifting or other athletic or work activities. The sleeves are attached to the shirt body at sleeve arm holes. Each sleeve has at one end a sleeve opening and an opposite end which attaches to the shirt body. A centerline of the shirt forms a curvilinear axis and extends longitudinally across a front portion of the upper shirt body and the sleeves from the sleeve arm holes to the sleeve openings.
