If you need to go about your day with confidence in your ensemble, try pairing a navy shawl cardigan with blue jeans. Go ahead and add a pair of white print leather low top sneakers to the equation for a carefree touch. A vivid example of transeasonal fashion, this look is an essential this spring. Think 50-year-old guys can't pull off cool off-duty style? This pairing is irrefutable proof of otherwise.
