This is the designated swimsuit for Joyful Athletic Club. The retail price was in the 7000 yen range. My child is small, so they wore it in grades 3-4, but because the fit is tight, I think it would fit younger children as well. I've listed the size as 110, but this isn't exact. The tag says waist 68-72, but even though it stretches, it felt very tight when my child wore it, so I think it's around 《waist 44cm〜54cm》. The staff at the reception desk also told us to buy a size 2 or 3 sizes larger than usual because it's a tight fit when trying it on. (My son said it was tight at 54cm and changed to a size M) The length is 34cm. I will send it via Yu-Packet Post Mini. Thank you.
