I get the Pure catalog but haven't ordered either. Somehow I feel they might be related to Poetry because they're both British companies and the catalogs arrive at the same time.
I just got two sweaters from Everlane and while they are very traditional in style and color (gray and navy, v neck and cardi) they are such nice quality -- very thick and soft. I also recommend the company's customer service. I ordered another item at the same time (a seed stitch mostly cotton sweater) and when it linted all over the place on first wearing, I complained. Within 24 hours they gave me a credit for a brand new sweater with free shipping and said I did not have to give the old one back.
I also thought I'd try a Boden cashmere. I used to shop with them a lot. However, I have had a hard time with sizing. My shoulders are somewhat broad, but I am otherwise small, and I find their jackets and blouses to be very tight in the shoulders and baggy in the bust. Knits are much easier. Also I have some older wool sweaters from there that I liked much when I first bought them, but which went pilly very quickly.
