I'm selling these because they don't fit my mother anymore. Size: M Approximate measurements (taken by hand): Waist (laid flat): about 26cm Inseam: about 55cm The waist is fully elastic, making them easy to fit and comfortable to wear. They are ribbed, so they have some stretch. The tag has been removed, but the fabric feels like 100% polyester. They can be used casually, for everyday wear. I don't see any noticeable stains, scratches, or fading, but I hope to do business with someone who understands that these are used items. Casual pants Track pants Workout clothes Black long pants
