Control price of fashion? (8)
I believe the answer is:
moderate
I believe this is a double definition.
'control' is the first definition.
(thesaurus)
'price of fashion?' is the second definition.
(fashion = mode, price of = rate)
(Other definitions for moderate that I've seen before include "Reduce" , "Temper" , "Become less intense" , "Medium in amount or intensity" , "Not excessively right- or left-wing" .)
