From J.Crew: Our classic fit has a little extra room and a just-right length. And it's the details that make this shirt truly special - like the custom label and beautifully finished seams from the inside out, so the sleeves are essentially made to be rolled. Plus, this shirt was crafted from cupro, which is just a smooth as - and way more durable than - silk, machine washable and made from recycled cotton linter at a zero-waste facility. 60% cupro/40% viscose. Machine wash.
