Thank you for viewing! (^o^) Please be sure to read the profile before purchasing. This item is [new and unused] and has been stored at home. The actual size is between S and M, so it can be worn by people who usually wear S or M. Those who wear M and prefer a looser fit may find it a bit small. The material is polyester, but it's a satin weave with a smooth, pleasant feel. The fabric is also sturdy, so it's extremely comfortable to wear＾＾ Above all, this pattern is irresistible for cat lovers♡ If you have the height, it would be perfect for elementary school students in the upper grades. Please see the actual photos for more details. Please note that it will be shipped folded small. *I am also selling on other flea market sites, so I may suddenly delete the listing. Thank you for your understanding. If you have any questions, please feel free to comment m(_ _)m
