Thong for a revealing entertainer (8)
I believe the answer is:
stripper
'entertainer' is the definition.
(stripper is a kind of entertainer)
'thong for a' is the wordplay.
'thong' becomes 'strip' (I can't justify this - if you can you should give a lot more credence to this answer).
'for' says to put letters next to each other.
'a' becomes 'per' (eg 'one a day' means 'one per day').
'strip'+'per'='STRIPPER'
'revealing' is the link.
Can you help me to learn more?
(Other definitions for stripper that I've seen before include "Paint remover" , "Exotic dancer" , "Teasing dancer" , "Erotic dancer" , "exotic entertainer" .)
