Although they look like denim with a clean silhouette, these leggings are made of thin, light, and stretchy cotton cut-and-sewn fabric, so they are extremely comfortable to wear. The authentic denim color has been given a silhouette that is not as tight as skinny jeans, making them easy for adults to wear. The elastic waistband is comfortable around the stomach. They also look great when paired with one-piece or tunic.
