I love this top.  It fits well and is VERY comfortable.  It's nice enough that it could easily be part of very nice summer evening outfit -- with some blousy pants or a cute skirt.  I like the folds over the chest because I don't wear a bra under it and those folds obscure any potential indecency if one finds oneself in a chilly room....

The reason it's so comfortable is the incredibly soft fabric.  I came to appreciate it when I ordered another prAna top which I thought would be made of similar cloth (prAna Women's Sabin Chakara Top) and found that the fabric on that one is VERY different - stiff and sort of hard and very disappointing.
