I am a big fan of Lands End cashmere. I have had other cashmeres that just did NOT last…I have a collection from Lands End with pieces that are probably 10 years old. I buy a piece or 2 every year (and have paid full price because their stuff rarely goes on sale and they sell out quickly in plus sizes, especially the new colors). This year, due to the economy, they had awesome sales and I basically got 3 pieces for the price of 2 ...some were only $60.00 and all had free shipping. I either hand wash my pieces or use Dryel to clean them…it works very well, especially to freshen the pieces or to remove smoky odors from a night out at an event, etc. As far as mail-order, Lands End has the best customer service and excellent quality. Once you order a piece and find your size, they stay fairly consistent. I am hard to fit, so I am used to having to order some things in the mail. Lands End provides a return label to send items back.  I think they produce a quality item that is worth the effort. Prior to the Lands End items, I also had good luck with Lord & Taylor. I had a sweater from them that I wore for years until I got a hole that could not be repaired. I would have gotten more, but Lord & Taylor had closed all their stores in my state by then. P.S. Lands End was rated very highly by Consumer Reports for cashmere this past Fall.
