- Size: 1 - Brand: Yu - Material: Cotton - Design: With strings Made in Japan Thank you for viewing. This is a pair of karate pants that my daughter used once a week when she was in elementary school (lower to middle grades). The size is 1, so I think it's about the size of a child who wears 130cm clothing. The length from the waist to the hem of the pants is about 67 cm. There are wrinkles, dullness, and signs of use, but there are no tears and the fabric is softer than new. How about for a spare pair? Because they are soft, her legs went up firmly during promotion tests. I have washed them, but I have not bleached them. Please refrain from purchasing if you are concerned or are a perfectionist.
