Wear warm clothes with cuff down? On the contrary (4,2)
'wear warm clothes' is the definition.
(wrap up warm)
'with cuff down? on the contrary' is the wordplay.
'with' becomes 'w' (abbreviation).
'cuff' becomes 'rap' (both can mean to hit).
'down? on the contrary' becomes 'up' (I can't explain this - if you can you should believe this answer much more).
'w'+'rap'+'up'='WRAP UP'
(Other definitions for wrap up that I've seen before include "put a sock in it" , "Be quiet - fold paper round - finish" , "Finish off - be quiet - put on warm clothes" , "Dress warmly or bring proceedings to an end" , "Informally finish, or put on warm clothes" .)
