This is an Andersen-Andersen sweater. It was worn by someone who is 165cm tall and weighs 55kg. The size is XS, which is a Japanese size S-M, leaning more towards S. It was a perfect fit, but I've come to prefer a looser fit, so I'm selling it. There are no noticeable scratches or stains, but it seems to have a lot of fuzz overall.
