Grace Kelly by the pool in ‘High Society’

Grace Kelly wears a swimsuit -- or maybe "bathing costume" is more like it -- in this PR photo from the 1956 film High Society. Kelly, as Tracy Lord, was age 27 when the film was released, and was paired quite improbably with 53-year-old Bing Crosby (as C.K. Dexter Haven) in the musical romance. It was Kelly's last feature film; she married Prince Rainier of Monaco the same year and became Princess Grace, giving up the film business.
