An undershirt including a main constituent portion made of stretchable materials that include a first-type material, a second-type material, and a third-type material. The first-type material has a straining force greater than a straining force of the second-type material, and the second-type material has a straining force greater than a straining force of the third-type material. The first-type material is arranged to cover at least part of musculus triceps brachii. The third-type material is arranged to cover at least a part of a lateral portion of musculus trapezius, at least a part of superior portion of musculus latissimus dorsi, and at least a part of a medial portion of musculus deltoideus in a vicinity of scapula. The second-type material is arranged in regions other than the regions where the first-type and third-type materials are arranged.
