 CONT: In the "Roof Garden" scene, Nadine is wearing high heels when  she does the "Magazine Cover" number. In the wings at the end of it,  she removes her headdress, discards her huge fan, and goes back  onstage to call Don Hewes out of the crowd to dance their old  number. Suddenly, shes wearing ballet slippers. In fact, in all of  her scenes with Astaire, she wears flat shoes, so as not to tower  over him.
