Worn only twice for about an hour each time: once for the entrance ceremony and once for photos. No eating was done while wearing it. It was only worn, so it's in very good condition. Thin knit fabric. I think you can wear it twice a year, from the autumn season to early spring. Please note that it has been stored at home and inspected by an amateur, so there may be oversights. Please refrain from purchasing if you are sensitive to such things. Please understand that this is a used item before purchasing. Clothing may be compressed during packaging. Due to childcare, it may take a little time to contact you or ship the item. Thank you for your understanding. No pets, no smokers. *The shipping method may be changed from Rakuraku Mercari Bin to Yu-Yu Mercari Bin depending on the situation.
