Scent of occasionally hairy woman, undressed (5)
I believe the answer is:
aroma
'scent' is the definition.
(synonyms)
'occasionally hairy woman undressed' is the wordplay.
'occasionally' means one should take alternating letters.
'undressed' indicates the central letters (the word removes the letters which clothe it).
The centre of 'woman' is 'oma'.
The alternate letters of 'hairy' are 'ar'.
'ar'+'oma'='AROMA'
'of' is the link.
(Other definitions for aroma that I've seen before include "Stink" , "Odour, mostly pleasing" , "Pervasive atmosphere" , "Pleasant odour" , "Food fragrance" .)
