These are pants I bought at the Suit Company a few years ago. They're made of a material that can be worn year-round, and the lining goes to about the knee. They also have great stretch, making them very practical. They are not part of a set. I've worn them casually, but there are no noticeable stains or damage, and they've been kept in good condition after being dry cleaned. Color: Gray Size: 38 (Waist 62)
