They were leather trousers, as I recall. Laced up at the sides; not sure if they were permanently joined at the top, or if they were just a front and a back that one had to completely tie together.

Nobody had a problem with the leather (although a peekaboo stripe of visible leg down the outside of each, covered in a criss cross of something that looked like shoelace was sometimes a surprise). That was just flavour detail.
