This is a button-down shirt with a check pattern from THE SHOP TK (made in Japan). The material is cotton. I bought this shirt because I liked the three-color check pattern, which was sold at the time as part of a project that focused on "Made in Japan." I'm selling it now because I've outgrown it. I don't think there are any noticeable stains. - Brand: THE SHOP TK (※Casual line of TAKEO KIKUCHI) - Size: Marked as L, but fits like a size M (※Suitable for people around 165-170cm tall. It may shrink initially due to the nature of cotton, but it won't shrink anymore.) Thank you for looking. No claims, no returns, please.
