Lee Radziwill's Style Evolution (PHOTOS)

Though placed in the shadows of her impeccably dressed, late sister Jacqueline Kennedy Onassis, Lee Raziwill has managed to forge a spot for herself on the list of American fashion icons. From her classic, tailored separates to show-stopping fur coats to little black dresses, it's no wonder she continues to lure the photographers' cameras.

In honor of Radziwill's 79th birthday on Saturday (March 3), we take a look back at the socialite's style. My favorite outfit has to be of her in 1967 wearing a simple sheath, pointed toe heels and voluminous hair. Be sure to vote on all her looks in the slideshow below.
