Discovered how Sikh men traditionally appear elegant (6)
I believe the answer is:
urbane
'elegant' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for urbane that I've seen before include "Cosmopolitan" , "Refined and civilised" , "Unbare, being suave." , "Smooth-mannered" , "Elegant and sophisticated - sounds like city type" .)
