Topman Drawstring Pants Elastic Waist Size 30S

I’m not exactly sure of the style of these pants tbh. They look like a nicer, dressy looking fabric with the elastic waist and drawstring. Not quite a sweatpant, not quite formal. If you know the style, leave a comment for me please! Pants are excellent condition, like new, with no imperfections. Feel free to request measurements or more pictures, Thank you for looking!
