Thank you for viewing. This is a uniform used when participating in events at a Minecraft esports class. My third-grade son wore it once for a short time over a long-sleeved T-shirt. I don't think there are any particular stains, but please forgive any oversights as it's a personal inspection. It's a size S, but I think it's around 150-160 cm. This uniform is required for wearing at the annual training camps and tournaments, and it costs over 7,000 yen at the regular price, so it's recommended!
