THE NEXT HALSTON? Halston is looking for a new creative director, and one name being bandied about for the gig is none other than Olivier Theyskens. According to sources, Vogue’s Anna Wintour is keen to find Theyskens, who recently exited Nina Ricci, a job in New York, and she is said to have been lobbying to get him installed at Halston. Over the past few months, the iconic brand has been putting its feelers out, and sources said it was at one point looking at Narciso Rodriguez and at London-based designer Marios Schwab to succeed Marco Zanini, who left the company last year after two seasons as creative director of the revived line. Halston executives said no decision has been made on a new creative director.
