Since the revival of Halston three years ago, the house has not shied away from its Studio 54 salad days. Even Liza Minnelli was there as the label relaunched. But Tuesday evening's presentation felt like a full bear hug of the disco years. With the lights dim to highlight a trio of glow-in-the-dark dresses and the familiar sound of disco over the speakers, the intricately draped jersey dresses designed by Marios Schwab looked like they belonged to the muses of "Xanadu," or a least a young Donna Pescow. Even the show notes read like an old Grace Jones song: "An evanescent aura of chiffon settles over weighty jewels." Regardless of the music, Schwab's designs were effortess, and aside from the gimmicky glowing dresses and jeweled bra, his peak-a-boo slits and plunging necklines would be considered sexy in any era.
