Turning some crasser perfume bottle up (7)
I believe the answer is:
repress
'bottle up' is the definition.
(I've seen this before)
'turning some crasser perfume' is the wordplay.
'turning' says the letters should be written in reverse.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'sserper' is hidden in the letters of 'crasser perfume'.
'sserper' reversed gives 'REPRESS'.
(Other definitions for repress that I've seen before include "Put in irons, maybe" , "bottle up" , "Silence" , "Check" , "Keep in subjection" .)
