Quality of your cashmere.
Cashmere garments come in 3 different grades, but the grades are never listed on the labels. If you want to determine the quality of cashmere then you should judge by its softness. The finer the width of the hairs, the softer the texture of the garments and higher the quality. Try to gently stretch the body of the garment to see if it snaps back. Lower quality cashmere won't snap back.
