Collette Dinnigan was in New York to talk up her new lower-priced range, Collette. The short, colorful baby-doll dresses and smocks all retail for less than $350. "It's about easy dressing," she said. "And it's a bit gypsy." But she was also here to show her high-end collection, and that, by contrast, took its cues from the designer's marathon Mad Men watching sessions. "I'm obsessed with the show's styling, how everything is so perfect," she said. Corseted dresses with full skirts were in abundance; a pink cotton version stitched with white raffia at the neckline and a chiffon in floral animal print were two highlights. It wasn't all strawberries and cream, though. Dinnigan's red-carpet clients still prefer sexy to sweet. For them, she served up black lace and studs.
