The waist is elastic and stretchy. These are not stiff jeans. My child wore them 4-5 times for school events. She prefers skirts, so she probably won't wear these again, and I'm selling them while they're still in good condition. There is a scratch on the front left knee (photo 3). There are also small scuffs on the hem and the back right side (photos 4 and 8). - Size: Waist approx. 30cm (photo 2) Inseam approx. 68cm (measured from the position in photo 7) - Design: Denim material Thank you for looking.
