☆ Size Marked size → M Length: Approximately 54cm Shoulder width: Approximately 37cm Sleeve length: Approximately 51cm Width: Approximately 40cm (measured from armpit to armpit) (Dimensions are taken with the garment laid flat) This size is likely a perfect fit for elementary and junior high school kids, or those with a small build. My child wore this in elementary school and outgrew it in junior high school (standard build). Unisex ☆ Color / Gray ☆ Material → 100% cotton ☆ Condition → There is some wear, but there are no noticeable stains or damage, and it can still be worn. Please check the photos for the color fading and the condition of the fabric. Although there are no noticeable stains, I rate it as "slightly dirty" due to the color fading.
