After searching for the perfect long cardigan/duster, I finally found THE ONE.  It's a little on the expensive side, but definitely worth it.  The material is incredibly soft, which is important for my sensitive skin.  If you have an aversion to itchy wool or other irritating fabrics, this is the sweater for you.  I purchased the pewter color, which is actually a little darker in person than the Amazon picture.  The only thing I will mention is that this sweater runs large.  I'm a size 8/10 and ordered a small based on the recommendation from the prAna website to order a size down.  It has a nice fitted look but it's not tight.  And I love the bell sleeves.  They provide extra room so that a long sleeve top is easily accommodated underneath without being tight around the cuffs.  I would say that the small size really fits like a medium.  And the Amazon picture does not do it justice at all -- it's very cute and even a little sexy.  If you have a chance, a more accurate depiction of this sweater is at the website Vickerey under the category jackets & wraps.  I love this sweater so much that I'm thinking of getting the other two colors as well.  Enjoy!
