Women's off-white & purple tie-dye cashmere batwing V-neck sweater - RIA 7A

We recommend washing your cashmere regularly, preferably in the machine, placed in a protective laundry bag. Choose a cold wool wash cycle and use a special wool detergent, with a maximum spin speed of 500 rpm.
You can also hand wash your cashmere, making sure not to leave it to soak for too long and rinsing it in clean water. Gently squeeze out the water in a towel. Then dry flat on a towel away from heat and light, and iron gently without stretching it out of shape or pulling on the knit.
