We offer free shipping in the USA. For international delivery, shipping and taxes are auto calculated at checkout when you fill in your address (including customs fees). Review our return policy
Because this is a personal care item, for hygiene reasons, we cannot resell bonnets that have been worn or tried on—even briefly—however, we do offer a 100% refund on return where the bonnet is too small - Note, this is limited to a lifetime maximum of 1 per person. For all other return scenarios, we can return if the bonnet has not been tried on.
Silver ion silk requires less cleaning due to the molecular silver ions which combat bacteria.

CLEANING
Hand wash in cold water or machine wash on a delicate setting in a ‘silk-only’ load.

If hand washing, use a mild detergent. Gently massage the fabric for one minute to activate dirt removal and then leave to soak for the next four minutes. Rinse in fresh cold water.

DRYING
Lay flat or hang in the shade until dry, away from the sun. Ironing and steaming is optional – keep on a low setting

STORING
A cool and dry place is always best for storage. Neatly fold and store in your Clementine Sleepwear box.
