This undone look appears to be pretty relaxed. From the easy silhouettes to the loose fits and drapes, it looks just about as comfortable as it gets. But how do you keep things looking good--and profesh--while still working this pajama dressing trend quite well? This pic says it all. From the topnot to the sleek open-toe sandal, there's so much here to work off of. Pair the two together with pajama pants or a really relaxed sweater like this and you've got a "done" undone look in a cinch.
