First, from Ann Taylor Loft's new "Lounge" collection, I purchased the "Rib Trim Cowl Neck" top in the black (it is pictured in the pewter melange). It is made from cotton and is very, very soft and comfortable. Though it technically is "lounge" wear, this item is as nice or nicer than many tops, sweatshirts, and sweaters: I would feel comfortable wearing it with a pair of nice jeans and black flats to the office on the weekend. In addition to the pewter melange and black, it comes in a lovely "pebble melange grey." The top is $49.50 (though I had a coupon from a previous purchase that effectively took 50% the purchase price); find it here.
Second, since I am desperate need of vegan work-appropriate winter coats, which are often impossible to find when you actually really need one, I also purchased the "Cotton Long Belted Coat" in the pictured "deep lake blue," which is the only color it comes in. Although the coat is made from cotton and lined with polyester, it is surprising substantial and heavy. In fact, I think it will be appropriate for weather above about 30 degrees absent snow. The coat is $168; find it here.
