Used for two years in physical education classes at school. I think I've only worn it for about 8-10 hours in total. It's for a girl, so I think she wore it carefully, but the collar is a little dirty, so please refrain from purchasing if you are concerned. (Washed) *I think the dirt might come off more if you use Uta-Maro soap or something similar. Color: Ivory Suitable height: 145-155cm *Discount available until December 25th. (Around 200-300 yen...)
