This is a karate uniform from Shin-Kyokushinkai. My husband wore it several times for practice. Would it be suitable as a training uniform? Size: 7 Color: Natural (Off-White) *This is a used item that has been worn several times. Although I washed it carefully each time, there are yellowing and stains in the areas marked with ○, on the right shoulder/arm, and overall, due to several years of storage. Please understand this before purchasing. *Please feel free to ask if you have any questions or concerns.
