Cashmere has become a staple in my wardrobe. It's warm, soft, and looks professional. It's an easy Fast Fallback on cold mornings, too.
I have been scouting out different brands, and here is what I have found:
Norstrom's Collection is the best I have bought. It wears well and has only minor pilling after multiple wears.
Talbots is a close second. It is not as lofty as some other cashmere, but it doesn't pill as bad either.
Ann Taylor - not bad, soft and lofty, but it does pill pretty quickly.
Halogen by Nordstrom - worst of the lot. Pills badly after each wear.
I have avoided J.Crew as their clothes tend to be geared for a less busty body shape.
Any brands that you all have had good luck with (or not)?
