A silk like regenerated fibre, quietly lustrous and machine washable.

Wash gentle and cold. A mild detergent on a delicate cycle. Cupro is kinder in use than many delicate textiles, which ask for dry cleaning only.
Reshape while damp. Smooth it back to shape and dry flat, away from direct sun.
Iron low. On a cool setting, from the reverse if it has a sheen.
