These are super-stretch tapered casual pants. They stretch a lot! They have a button, but it doesn't open or close; they're the type you pull on with a stretchy waistband. If the size fits you, you can wear them stylishly. They were a little small on me, and I've only worn them once, so they've been in storage and are almost new. Waist: 68-76cm Inseam: 70cm Leg opening: 14cm Thank you.
