Ralph Lauren striped polo shirt, size 24M, comfortable cotton material. - Brand: Ralph Lauren - Size: 24M - Color: Blue/Navy - Design: Striped - Material: Cotton Size 24M, but it's equivalent to Japanese size 80. Thank you for looking. I received this as a gift, but the season didn't match, so I only wore it a few times. However, I washed it each time, so there is some fading and marks from clothespins? on the fabric. If you don't mind these, please consider purchasing it. (^^)
