This school shirt is made of a comfortable blend of polyester and cotton. Would this be suitable for your child's school shirt? I bought it for 2600 yen, but it became too small before I could wear it. When shipping, I will remove the plastic collar stays and slightly compress the shirt for shipping. Please purchase if you understand this. - Brand: SKYNER - Material: 65% polyester, 35% cotton - Size: 160A Thank you for looking.
