Man turned elegance into shame (8)
I believe the answer is:
disgrace
'shame' is the definition.
(I know that shame can be written as disgrace)
'man turned elegance' is the wordplay.
'man' becomes 'sid' (man's name).
'turned' says the letters should be written in reverse.
'elegance' becomes 'grace' (I've seen this in another clue).
'sid' back-to-front is 'dis'.
'dis'+'grace'='DISGRACE'
'into' acts as a link.
(Other definitions for disgrace that I've seen before include "Bring shame upon" , "Dishonour, ignominy" , "Cadger is in state of ignominy" , "scandal" , "State of dishonour" .)
