To celebrate his label’s birth as an official Paris couture house, Alexis Mabille went one better than handing out sugared almonds — he sent them down the runway. The French designer’s first show since being made a bona-fide holder of the haute couture appellation was a saccharine affair, from the bubblegum-pink venue to the frothy confections on display. It opened with a sheer pink chiffon blouse with white lace sleeves and a froufrou peplum, paired with narrow pink radzimir pants. Netting was sprinkled throughout, from the layered dotted veil of a flirty white cocktail dress to the curtainlike Neoprene mesh of a sweeping pale yellow Cinderella gown. Ironically, a sober black belted tuxedo dress, cut away in the front to show plenty of leg, was the strongest look in the show.
