Initially a milliner for Bergdorf Goodman (and, famously, Jacqueline Kennedy), Roy Halston Frowick launched his eponymous womenswear label in 1968, buoyed by his friendships with a number of socialites and celebrities. The label became noted for its luxurious but minimalist, modern designs such as heavyweight cashmere evening dresses, ultrasuede wrap coats, and simple jersey sarongs. Halston expanded to include menswear and perfume in 1975. In its heyday, the label was known for A-list clientele including Lauren Bacall, Bianca Jagger, Liza Minnelli, and Liz Taylor. Newsweek dubbed Halston "the best designer in America" in 1972,

Following the sale of his label and subsequent death in 1990 Halston was revived in autumn 2008 by Harvey Weinstein, Jimmy Choo’s Tamara Mellon, and stylist Rachel Zoe. The first collection, designed by Marco Zanini was shown in New York in February 2008. Halston is now led by London-based designer Marios Schwab with creative input on the 'Halston Heritage' line from actress Sarah Jessica Parker.
