I used these in junior high school, but as I've gotten older, the shape no longer suits me. I've set the size to M, but please don't rely on that. The correct size is as follows: 28x30 (This is American pant size notation.) ↓ 29 inches: Waist 30 inches: Inseam 29 corresponds to a size S to M. We apologize for any inconvenience, but we appreciate your understanding.
