Playsuits have come and gone in a faddish way throughout the past five years or more, but for spring 2011 both the playsuit and jumpsuit have gone beyond being either in or out; the trend has carried over, but will either work or fail based on the quality and uniqueness of the pieces you choose. That's largely a matter of what works for you: but a piece like Opening Ceremony's ruffle onesi - with its gathered fabric, cinched waist, and steely grey colour - is one I can only imagine as a worthwhile investment piece. Turn it into a simple summer staple with sandals, or as a night-time statement piece with heels, a belt, and lashings of jewellery.
