Win heart cavorting naked? (2,3,3)
I believe the answer is:
in the raw
'naked?' is the definition.
(I've seen this in another clue)
'win heart cavorting' is the wordplay.
'cavorting' indicates anagramming the letters.
'win'+'heart'='winheart'
'winheart' anagrammed gives 'IN THE RAW'.
(Other definitions for in the raw that I've seen before include "Naked, or without refining influence" , "21 26 [IN THE ALTOGETHER]" , "without clothing at last?" , "plain" , "Undressed" .)
