Frequently Asked Questions
The majority of our pieces are crafted from 100% cashmere or 100% baby goat cashmere, sourced from Inner Mongolia and wove by our dedicated manufacturing partners. A small selection of styles feature signature blends, including cashmere / silk for a luminous drape, cashmere / cotton for lighter layering, and cashmere / linen for warm-weather pieces. Each product page confirms the exact composition.
Baby goat cashmere is harvested from the first combing of young cashmere goats. The fibres measure around 13.5 microns, finer than standard cashmere at 15–19 microns. This results in a softer handle, lighter weight, and more lustrous finish. Each animal yields just 30g per year, making it one of the world's rarest natural fibres.
Hand wash in tepid water with a specialist cashmere detergent for 5–10 minutes, rinse gently, and lay flat to dry away from direct sunlight. Machine washing on the most delicate setting at 30°C is also suitable. Always store clean and folded, never hung.
