Statesmen may wear it with a black tie (6)
I believe the answer is:
tuxedo
'black tie' is the definition.
(synonyms)
'statesmen may wear it' is the wordplay.
I cannot really see how this works, but
'wear' could be 'tux' (tux is a kind of wear) and 'tux' is located in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is present in the answer.
The remaining letters 'do' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'with a' is the link.
Can you help me to learn more?
(Other definitions for tuxedo that I've seen before include "Dinner jacket (US)" , "American dinner jacket" , "An American monkey-suit" , "American DJ" , "Garment" .)
