Well-made garments require equally well intentioned care. Wash instructions can be found on the care label inside each garment. But a simple synopsis of fibres is as follows:

For Cotton, Linen and Silk - Hand Wash Cold with Mild detergent. Do not use Bleach. Press out excess water using a clean dry towel. Hang to dry in the shade and away from direct light.

For Wool & Knits - Dry Clean Only.
