Robbie channeled the 1959 poolside Barbie for the teaser trailer ... Standing in the iconic one-piece bathing suit, Robbie, 32, sports white sunglasses, blonde curls, and a pair of gold hoops.

The sweeping gown that the new Barbie wears is a modern take on the black-and-white bathing suit from the 1959 doll. Even the new Barbie's sunglasses are an ode to the Barbie from back then.
