The pillbox is a round, brimless hat with straight sides and a flat top. The design was introduced by (Gilbert) Adrian for Greta Garbo in the 1932 film As You Desire Me. This type of pillbox was generally worn as a tilt hat. The pillbox became iconic when Halston designed one for Jackie Kennedy (which she wore toward the back of her head) in the early 1960s. Pillboxes grew gradually taller throughout the decade.
