Is there a way to keep cashmere from pilling?

Answer 1

Yeah-- not to wear it! Seriously, though, the pilling is caused by friction- the underarms, the sides of the chest, washing, and such. Wearing a lined jacket over it will help, but usually the only thing you can do is get a sweater shaver, and try not to move your arms so much.

Answer 2

there is a shaver made for that, it shaves off the excess without damaging the cloths, battery operated and cheap to buy.
