Show a drape off (6)
I believe the answer is:
parade
'show' is the definition.
(I know that parade is a type of display)
'a drape off' is the wordplay.
'off' indicates an anagram.
'a'+'drape'='adrape'
'adrape' with letters rearranged gives 'PARADE'.
(Other definitions for parade that I've seen before include "March-past of troops etc." , "Organised procession of displays, performances, etc" , "Flaunt; ceremonial march" , "Cavalcade or procession" , "Assembly of troops for inspection" .)
