Once Wittop returned to America after the war, he had a stint dressing show girls and dancers at the Latin Quarter (nightclub) in New York City. He then formed his own dance company in 1951 and for the next seven years toured the US and Europe. He returned to theatre design at the behest of director Harold Clurman, who saw his show and asked him to design his 1959 Broadway production of George Bernard Shaw's Heartbreak House. He actively worked in New York for the next fourteen years.
