Changed untidy birthday suit (6)

I believe the answer is:

nudity

'birthday suit' is the definition.
(thesaurus)

'changed untidy' is the wordplay.
'changed' is an anagram indicator.
'untidy' with letters rearranged gives 'NUDITY'.

(Other definitions for nudity that I've seen before include "The altogether" , "feature of post-watershed TV?" , "state barely acceptable to some colonists" , "State of complete undress" , "of discarded clothing" .)

I've seen this clue in The Globe and Mail.
