Hedi Slimane paid a ’90s-style homage to Courtney Love by sending out a string of models donning delicate diamanté tiaras at Saint Laurent’s Spring 2016 show—and instructed via live-tweet that it be “worn with everything.” Interpretations were also aplenty recently on the runways of Louis Vuitton, who subverted the femininity of the accessory with a futuristic take, while ornate flower and fauna metalwork versions at Dolce & Gabbana commanded a more imperial presence. If that’s not enough incentive, this fall, look for Assouline’s stunning three-volume book set dedicated to the venerable Parisian jeweler Chaumet, who continues to reinvent the magical adornment—its first opulent tiaras were created for Empress Joséphine de Beauharnais (the first wife of Napoleon I)—for each new age. • Caroline Cagney.
