I can't tell the brand, size, or material because there are no tags. I bought this a few years ago at a department store in Futako-Tamagawa. I think it was a select shop, but I'm sorry, my memory is vague. I usually wear a size S, but it's a relaxed fit and doesn't feel small, so I think it would be okay for someone who wears a size M. (I've registered it as S.) The color is a muted pink. The photos aren't taken very well, but it's more of a salmon pink. It's a bit sheer and made of a material that you can wear casually. Thank you for your understanding. Length: Approximately 62cm
