These are Petit Bateau fleece-lined long pants. Suitable for children approximately 110-120cm tall. Originally, they had a drawstring for adjustment. Since my child couldn't tie the drawstring, I added elastic. If you don't need the elastic, you can cut and remove the white elastic to return them to their original condition. There is also elastic at the ankles. This was part of the original design. The elegant check pattern made them seem suitable for formal occasions. They are soft cotton long pants in a navy and gray check pattern, and my child seemed to find them comfortable to wear. - Color: Navy and gray check pattern - Material: Soft cotton - Waist: Elastic and adjustable drawstring Thank you for looking.
