Spot Les out without a shirt (7)
I believe the answer is:
topless
'without a shirt' is the definition.
('shirt' can be 'top' (I've seen this in another clue) so maybe 'without a shirt' can be ''topless')
'spot les out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'spot'+'les'='spotles'
'spotles' with letters rearranged gives 'TOPLESS'.
(Other definitions for topless that I've seen before include "Wearing no clothing above the waist" , "Revealing" , "Bare-breasted" , "Half naked" , "Without a shirt, vest or bra?" .)
