Halston's own first clothing collection was presented in New York in 1968, in a comfortable bohemian space unlike the purist, overbearing architecture previously common to couture houses. He quickly became a trusted designer and personal friend to the Beautiful People, spending many evenings with them at the famed disco Studio 54. Halston called this "the best show in town", as he could engage in conservation while observing his clients (and potential clients), studying them all through the lens of a designer.
