The knee repair next week will be during really hot weather; I don't know if the bandages will fit under the slim hem of a couple of my Capri pants, but I may have a couple of other pair tucked away. I have to look around. I'll take a loose pair of fleece pants in case others don't fit.
eBay is a place that has buyers and sellers of vintage clothing, if you want to sell the old garments, or give them to someone who can do it. I sold some vintage WWII clothes of my mother's some years ago. (I don't keep most of that either. I am not a museum.)
