Unbecoming to be in drag, if getting a makeover (5,3)
I believe the answer is:
infra dig
'unbecoming' is the definition.
(thesaurus)
'in drag if getting a makeover' is the wordplay.
'getting' is a charade indicator (letters next to each other).
'a makeover' is an anagram indicator (I've seen this in other clues).
'drag'+'if'='dragif'
'dragif' is an anagram of 'fradig'.
'in'+'fradig'='INFRA DIG'
'to be' is the link.
(Other definitions for infra dig that I've seen before include "Rigid fan may be lacking in dignity" , "Unworthy" , "Demeaning (Latin)" , "Such as one would not stoop to" , "Beneath one" .)
