These tights were purchased at MUJI a few years ago. I am 160cm tall and my shoe size is 24.5cm, so I believe these are size M-L. I've only worn them about twice each, and they've been stored folded. There are some wrinkles, but they are almost like new with no pilling or other signs of wear. (The second navy pair from the bottom has a slight fuzziness.) Thank you. m(*_ _)m
