1935 film starring Fred Astaire and Ginger Rogers and featuring the song Cheek to Cheek (3,3)
I believe the answer is:
top hat
(Other definitions for top hat that I've seen before include "It's seen with tails" , "Formal headgear of lofty sort" , "Formal headgear for man" , "1935 Fred Astaire/Ginger Rogers film" , "14 headgear" .)
