The new fabric has been pre-washed before being used for production. The actual color is a slightly darker beige. It is 100% cotton. It should fit those with shoe sizes around 28-29 cm. You don't need to be too strict about the size, like with shoes. The width is 10 cm. It can be washed at home and worn repeatedly. It will become more comfortable with wear. As it is handmade, there may be slight variations. The color impression may vary slightly depending on the monitor. Thank you for your understanding.
