2: Cardigan

The cardigan is the only entry on this list to be both sophisticated(复杂的) and cozy(舒适的). Over a dress, under a suit jacket, buttoned, unbuttoned -- the multipurpose cardigan is both an outfit-changing accessory(配件) and a shirt for chilly(寒冷的) days. In a pinch(匮乏), a cardigan is also a great casual(随便的) Friday replacement(更换) for the suit jacket. Go green or red to provide your outfit(机构) with an instant splash(飞溅的水) of color. While saggy(下垂的)cardigans have pretty much cornered the market on weekend comfort, a tight, fitted cardigan helps you project a confident workplace demeanor(风度).
