Zoe Saldana  wasn't nominated for an Oscar at the 2010 Academy Awards, but she made fashion history with the ombré purple gown she wore on the red carpet that year. Her Givenchy  Haute Couture design, a fashion-forward choice that blended unexpected textures like crystals and ruffles, landed the actress on many a best dressed list. The high-style move was nothing new, but rather in the tradition of Nicole Kidman , whose chartreuse Christian Dior  gown in 1997 was among the first instances of truly modern couture appearing on the red carpet.
Couturiers have always had a special relationship with celebrities, who need jaw-dropping dresses to wear for particularly glamorous events.
