I'm not sure where I got them. I was looking for brown and black vertical striped thigh-highs and these popped up. They aren't what I was originally looking for, but I think they still worked out pretty well
I'm sure you could find them by looking up the same thing I did (the brown and black vertical striped thigh-highs) in a search engine.
I do know the thigh-highs I ended up with are by music legs. Maybe that will help?
