This is the gymnastics uniform from Aiai Gymnastics Club. It's a set of a t-shirt and shorts, plus a bag. The size of the t-shirt is unknown, but the shorts are size 160, so I think the shirt is size 150 or 160. There's a little bit of pilling, but it's still in good condition and can be worn. For those joining Aiai Gymnastics Club, please consider this.
