Oh, Nancy! You may have been born a celeb (to Rat Pack dad, Frank Sinatra) but you certainly made your mark as an artist in your own right. Your musical collaboration with country/western singer Lee Hazlewood is one of the best of all time, hands down. Style-wise, you were a siren of the 60s who made the go-go boot the go-to boot with "These Boots Are Made for Walkin." Happy birthday! Our gifts to you, below.
