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 as strict as you would with shoe sizes. The width is 10 cm. It can be washed at home and worn repeatedly. It will soften with wear. As it is handmade, there may be slight variations. The color impression may differ slightly depending on your monitor. Thank you for your understanding.
