Thank you for viewing. This is a Comme Ca ISM shirt. The sleeves have strings inside, and you can fasten them with buttons to make them 3/4 sleeves. It's thin, so it can be worn as a light outer layer, or it looks cute layered with a hoodie. It's hardly been worn, and my child has outgrown it, so there doesn't seem to be any stains to the untrained eye, but please understand that it has been stored by an amateur. Also, please be aware of wrinkles.
