Lightweight chiffon (polyester) with a floral print and a magnetic ball-and-barrel clasp. Hand wash cold in a mild detergent or spot clean with a damp cloth, keeping the metal clasp out of water where possible; drip dry away from direct sun so the print doesn't fade, and never iron directly over the magnet. Because sheer chiffon snags easily on rough jewellery or nails, it's worth putting this on last, after any other jewellery, to reduce the risk of catching the delicate fabric.
