This is a baby hat from Ralph Lauren. It's an easy-to-wear hat, and it's reversible in white and light blue. The white side is terry cloth. This is an amateur measurement, but the inside circumference where it touches the head is approximately 40cm. It was a gift, but it didn't match the season, so it was used only a few times. There are no noticeable scratches or stains, and I believe it is in relatively clean condition. However, please refrain from purchasing if you are sensitive about home cleaning. Thank you.
