Nicole Miller has grown a more successful business than many of the other designers showing this week, and tonight s collection made it clear why. One frock after another, in sequined geometric patterns or elaborate pintucks, would work equally well whether you re pushing 25 or 45. Working with a more subdued palette than usual ("Everyone thinks of me as the color person!" Miller joked backstage), the designer experimented with lacquered fabrics that yielded standout faux-leather and velour biker jackets. In an era in which Michelle Obama moves more clothing than an Olsen twin, Miller s sophisticated-but-fun wares feel just right.
