It is intended to provide a garment for electrically stimulating muscles to be used for, e.g., rehabilitation or exercise whereby an electrode can be conveniently provided at such a position as allowing the electrode to stimulate the neuromuscular junction of a muscle to be moved in toning up the muscle through electrical stimulation on the muscle by taking advantage of the muscular contraction caused by electrically stimulating the muscle. A garment (A1) for electrically stimulating muscles which comprises the garment main body (1), a required number of openings (2) which are provided in the garment main body (1) in such a manner that each opening is located at the neuromuscular junction or in the neighborhood of the neuromuscular junction of a muscle to be moved in the case where a wearer wears the garment main body (1), and electrodes (8) provided at the respective openings (2) in such a manner that each electrode located on the skin surface at the neuromuscular junction or in the neighborhood of the neuromuscular junction of a muscle in the case where a wearer wears the garment main body (1).
