The strength of Rag and Bone Spring 2010 collection is uncomplicated pieces like a cargo-green army parka layered on top of an easy, oversize tuxedo shirt and a little dagger-print skirt; or a gray silk cropped jacket thrown over a couple of drapey cutaway tanks and leather pants that somehow managed to be skinny and slouchy at the same time. You could complain that drop-crotch long johns are a little heavy for spring.
