All cashmere can be dry cleaned or hand washed. Hand washing cashmere will actually make it even softer over time.
Soak the garment in sudsy, lukewarm water for 5 minutes, then gently ‘squish’ to let the suds soak through the fibers. Rinse in lukewarm water using the same ‘squishing’ action – never wringing – until the water is clear. Roll the garment in a towel to remove the extra moisture and speed drying.
After washing all garments should be re-shaped while damp and lay flat to dry, away from heat and sunlight. Smooth it back into shape, gently coaxing any facings or trims back to the correct size. This is an important part of the process so your garment can retain its shape.
