Lightweight stripey socks are a one size fits most item. Nylon/Poly. Great with breeches for the men, and skirts for the wenches. Stretchy enough for guys, even big guys. These are not the thick woven version, but more like tights so ladies know how to use them. And for the men, are similar in thickness to a dress sock. They are smooth with no grain so they create less friction for slipping over boots. They are perfect for carrying around at an event when an athletic sock works in the morning, but gets too tight as the foot swells from heat in the afternoon. Just switch out socks to the lightweight stripey sock and pillage on!
