UNIQLO HEATTECH Seamless Leggings Gray Used a few times and stored after outgrowing them. There is some slight abrasion on the back. - The thick fabric and HEATTECH function make them very warm, so you can look sleek even in cold weather with just one layer. - The wide waistband ribbing shapes the stomach, lifts the hips, and makes the thighs look slimmer. - Using a special knitting machine without seams makes your legs look longer and slimmer, helping to improve your style. Thank you for looking.
