... nude except for lingerie, finally (4)
I believe the answer is:
bare
'nude' is the definition.
(I know that nude can be written as bare)
'except for lingerie finally' is the wordplay.
'except for' becomes 'bar' (I've seen this in another clue).
'finally' indicates one should take the final letters.
The final letter of 'lingerie' is 'e'.
'bar'+'e'='BARE'
(Other definitions for bare that I've seen before include "Expose" , "Not clothed" , "Naked or empty" , "Unclad" , "Uncovered - unfurnished - unadorned" .)
