Change into suit (6)

I believe the answer is:
I believe this is a double definition.
'change into' is the first definition.
(thesaurus)
'suit' is the second definition.
('become' can be a synonym of 'suit')
(Other definitions for become that I've seen before include "Flatter", "Develop into something", "Evolve into; suit", "Change into - suit", "Suit, befit".)
I've seen this clue in The Times.
