A garment with a crotch part for covering at least part of a lower body of a wearer, the garment having two leg portions coupled together, comprising:

• a main body having stretchability;
• a first tightening portion (3) having a tightening force stronger than a tightening force of the main body, the stronger tightening force having lower stretchability;
• and
• a second tightening portion (4) having a tightening force weaker than the tightening force of the first tightening portion, the weaker tightening force having greater stretchability, wherein
• the first tightening portion (3) is formed such that a primary first tightening portion (3a) provided at a back side of a lower leg portion of the garment and a secondary first tightening portion (3b) provided at an inner side of a thigh portion of the garment are coupled to each other at an inner side of a back of a knee portion of the garment,
• the primary first tightening portion (3a) of the first tightening portion includes an inner portion linearly extending upward along an inner side of the lower leg portion from a vicinity of an inner side of an ankle portion to the inner side of the back of the knee portion and an outer portion extending from a vicinity of an outer side of the ankle portion to an upper calf portion of the garment along an outer edge of the calf portion that curves to protrude outward and extending obliquely on the upper calf portion to the inner side of the back of the knee portion,
• the secondary first tightening portion (3b) of the first tightening portion extends continuously upward along an inner side of a leg portion from the inner side of the back of the knee portion beyond the inner side of the thigh portion to a crotch portion where the leg portions are coupled together, and
• the second tightening portion is formed in a section for covering the calf portion surrounded by the primary first tightening portion (3a) of the first strong tightening portion.
