CHIC CONFECTION: Marie-Hélène de Taillac is going sweet. The jewelry designer has teamed with Ladurée for its latest collaboration of fashion macaron sets. The limited-edition coffret includes six colorful flavors, hand selected by de Taillac: chocolate, cassis violet, rose petal, lemon, orange blossom and pistachio. The confections are all brightly colored, a nod to the designer’s multihued gems. The box itself depicts de Taillac’s “Rainbow” necklace, featuring gold sequins and the piece’s multicolored briolette gemstone. The package retails for $24. To celebrate the partnership, Ladurée will also display Marie-Hélène de Taillac-inspired window installations. The collaboration launches in Tokyo and Paris on Thursday and Stateside on Friday. New York City got a sneak peek at the colorful collection on Tuesday, when the Marie-Hélène de Taillac store on the Upper East Side unveiled its own Ladurée window display.
