Clothing stylist perhaps bucks including symbol (8)
I believe the answer is:
designer
'clothing stylist' is the definition.
'perhaps bucks including symbol' is the wordplay.
'perhaps bucks' becomes 'deer'.
'including' means one lot of letters goes inside another.
'symbol' becomes 'sign' (I've seen this before).
'deer' placed around 'sign' is 'DESIGNER'.
(Other definitions for designer that I've seen before include "Producer" , "One who determines the look of something" , "Architect or couturier, say" , "Custom-made" , "Theatre set creator" .)
