Outstanding feature associated with a mate in Bow (5)

I believe the answer is:
china
'mate in bow' is the definition.
'china' can be an answer for 'mate' (cockney rhyming slang, mate is china plate). I am not sure about the 'in bow' bit.
'outstanding feature associated with a' is the wordplay.
'outstanding feature' becomes 'chin' (facial feature).
'associated with' is a charade indicator (letters next to each other).
'chin'+'a'='CHINA'
Can you help me to learn more?
(Other definitions for china that I've seen before include "Dishes, vases or ornaments" , "Ceramics; friend" , "Tableware; country" , "Porcelain; friend" , "country out east" .)
