Soaked female wearing second-hand clothes (7)
I believe the answer is:
infused
'soaked' is the definition.
(infusing is a kind of soaking)
'female wearing second-hand clothes' is the wordplay.
'female' becomes 'f' (abbreviation).
'wearing' becomes 'in' (as in being 'in' certain clothes).
'second hand' becomes 'used' (second hand can mean previously owned or used).
'clothes' means one lot of letters goes inside another (some letters clothe or cover others).
'in'+'used'='inused'
'f' put inside 'inused' is 'INFUSED'.
(Other definitions for infused that I've seen before include "poured in" , "as 27 [HERBAL TEA] did" , "Inculcated" , "as the tea maker did" , "Did steep" .)
