Like his name, 'Halston' fizzles out before it ends

'Halston' is the biographical story of Roy Halston (Ewan McGregor), the American fashion designer who started out his career as a humble milliner in the late '50s. He quickly became a household name after designing the pillbox hat for Jacqueline Kennedy in 1961, and the series documents Halson’s eventual cracking of the American fashion industry, his meteoric rise to fame, his saturation of various market avenues, and his eventual fall from grace.
