Scruffy representation of nudity (6)
I believe the answer is:
untidy
'scruffy' is the definition.
(similar in meaning)
'representation of nudity' is the wordplay.
'representation of' is an anagram indicator (I've seen this in other clues).
'nudity' with letters rearranged gives 'UNTIDY'.
(Other definitions for untidy that I've seen before include "Not inclined to be neat" , "Not neatly arranged" , "Disorderly, dishevelled" , "Cluttered" , "Dishevelled, messy" .)
