This is a school shirt for girls, size 170B, with stain-resistant and wrinkle-resistant properties. - Model: FG3600R - Size: 170B - Material: 65% Polyester, 35% Cotton - Features: Stain-resistant, wrinkle-resistant shirt - Gender: Girl Thank you for viewing. This is an authentic product purchased from the school upon entering a Tokyo Metropolitan high school. I bought it with some extra room, but it was too big. I purchased two shirts of the same size, so this one is unopened. How about a new shirt for入学, or for entering a new school? *Shipping will be done with the collar stays removed and compactly packaged. Thank you.
