Scotland makes some of the best cashmere sweaters. Italy's cashmere seems to be more stylish with Scotland level of quality. I find Loro Piana makes the best cashmere sweaters in both quality and style. Also, Brioni cashmere sweaters rank among the best. Malo, Tse, Hermes, Gucci, Ralph lauren Purple label, Armani Black Label, etc. make superior products. Bergdorf, Barneys NY, NM, etc. house brands can be good deals, especially if you can wait for the Fall sales.
