Inspired by a ballerina pirouetting in a jewelry box — a point made by the dancer at the show’s entrance — Monique Lhuillier sent out a tight lineup of princess and trumpet gowns heavy on tulle, beading and Chantilly lace. The ready-to-wear looks that opened the show were elegant, particularly the cropped top with a crisscross back and a tea-length skirt. Shades of lavender, peach, gold and mint were a nice break with tradition, and added to the designer’s fairy-tale vision.
