The pants have a slim fit and no stretch. Size M would be suitable for those with slender legs. *These are designed to be slim-fitting, so they run small, closer to a size S. I bought these but they were too tight, so I'm selling them. ^_^ These white and black damask patterned half pants have an elastic waistband with a drawstring for a comfortable fit. - Color: White and black damask pattern - Design: Damask pattern - Waist: Elastic waistband with drawstring Thank you for looking.
