Shelley became a Charlie's Angel in 1979. Her character Tiffany Welles was described as a sort of Grace Kelly-Lauren Bacall type of Angel, a very classy Angel. She sported a pair of iconic suspenders in a few Charlie's Angels episodes as well as in some promo pics for the show. The image of Shelley in those suspenders is so familiar to many a Charlie's Angels fan that it has reached icon status in itself.
