Outrageously show several topless! (6)
I believe the answer is:
reveal
'outrageously show' is the definition.
'reveal' can be an answer for 'show' (revealing is a kind of showing). I'm not sure about the 'outrageously' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for reveal that I've seen before include "'Disclose, divulge (6)'" , "Make public" , "Expose or display" , "Remove cover, unveil" , "window, in part" .)
