Nudity abroad is out of order (6)
I believe the answer is:
untidy
'out of order' is the definition.
(not in order)
'nudity abroad' is the wordplay.
'abroad' indicates an anagram.
'nudity' with letters rearranged gives 'UNTIDY'.
'is' is the link.
(Other definitions for untidy that I've seen before include "Disordered" , "Far from neat" , "Dishevelled, messy" , "Disorderly, messy" , "Disorderly, dishevelled" .)
