Make weird changes, even more unstylish (7)

I believe the answer is:

dowdier

'even more unstylish' is the definition.
(dowdy can mean unstylish or poorly dressed)

'make weird changes' is the wordplay.
'make' becomes 'do' (synonyms).
'changes' is an anagram indicator.
'weird' anagrammed gives 'wdier'.
'do'+'wdier'='DOWDIER'

I've seen this clue in The Times.
