It’s one of life’s many cruelties that you cannot always wear whatever you want. Just because you’re lucky enough to have amassed a haul of sparkling baubles, a covetable gala invitation, and the desire to drip with diamonds from all available limbs and lobes does not, by any means, mean that you should. As Yves Saint Laurent once said, elegance is restraint. What he meant? Bring out the good stuff, pare it down to the essentials, and employ a considering eye. Or an editor’s eye.
