In keeping with the season’s throwback mood, slip on a pair of supersized tortoiseshell frames to lend any outfit some signature ’60s swing. But rather than serving as a finishing touch, make them the starting point for your entire look. Take Gucci’s Jackie O-style sunglasses, which are crying out to be worn with a suede trench coat, a crisp shirt and wide-leg pants, or an elegant skirt suit – in other words, anything that recalls the former First Lady’s impeccable wardrobe.
