Black leggings made of stretchy material, with an elastic waistband. The size is listed as 150 (140-160), but I think it's suitable for children around size 140. The material is soft and stretchy, so it can accommodate a wide range of sizes, but because it's a slim design, it's recommended for children around size 140. These leggings are comfortable to wear because they are made of a material that is resistant to pilling, highly stretchy, and soft. - Color: Black - Elastic Waistband: Yes - Material: Stretchy material Thank you for looking.
