Short-sleeved T-shirt with a red and white striped design, made of 100% cotton for a comfortable feel. - Brand: GU - Color: Red and white stripes - Material: 100% cotton - Style: Short sleeve Thank you for viewing. No stretching around the collar or under the sleeves. The size is L, but it has a short length design, so even if I wear high-waisted denim at 154cm, my belly button will peek out if I raise my arms.
