These pants were purchased from GRL a few years ago. They can be worn for office casual wear! The tag with the size on it has been cut off. I believe it is a size M. I don't think there is much sign of wear and tear such as stains or scuffs, but please understand that they are not new. These items are stored, inspected, packaged, and shipped by a private individual. Please refrain from purchasing if you are concerned. [Measurements by hand] Waist: 64 cm Total length: 88 cm Inseam: 61 cm Width at thigh: 46 cm There is elastic on the back of the waist. If you have thick calves, you may feel pressure on your calves when you squat.
