Star in retro production to get makeover artist? (9)
I believe the answer is:
renovator
'makeover artist?' is the definition.
(someone renovating or making over something)
'star in retro production' is the wordplay.
'star' becomes 'nova' (nova is a kind of star).
'in' is an insertion indicator.
'production' indicates an anagram.
'retro' is an anagram of 'retor'.
'nova' going inside 'retor' is 'RENOVATOR'.
'to get' is the link.
(Other definitions for renovator that I've seen before include "One who restores" , "Restorer of good condition" , "One freshening up" .)
