A pair of green sweatpants. They are so worn in the seat they are transparent. I can't find any more like them so I have bought some fabric and will use the old ones like a pattern to make a couple of pair like them. It is a damn shame that you can hardly buy anything that doesn't have synthetics in the mix. People should just refuse and we would see natural fiber fabrics again. I even had a hard time finding 100% cotton fleece and french terry, but I did.
