- Ribbed Cuffs and Hem: Snug ribbing at the sleeves and hem keeps the fit neat and holds its shape wear after wear.
Perfect For
Pairing with tailored trousers and smart shoes for the office, teaming with dark denim for a polished weekend look, layering under a blazer or wool coat for extra warmth, or wearing on its own as a standalone top on cooler evenings.

- Do not bleach.
- Lay flat to dry to help the knit hold its shape.
