Pantomime character made to look silly (4)
I believe the answer is:
dame
'pantomime character' is the definition.
(I've seen this before)
'made to look silly' is the wordplay.
'to look silly' indicates anagramming the letters (I've seen this in other clues).
'made' is an anagram of 'DAME'.
(Other definitions for dame that I've seen before include "Panto cross-dresser" , "Peeress" , "Pantomime lady" , "See 21" , "Broad" .)
