Cabaret singer to return in May, perhaps, getting minimal coverage (9)
I believe the answer is:
brazilian
'minimal coverage' is the definition.
(style of waxing)
'cabaret singer to return in may perhaps' is the wordplay.
'cabaret singer' becomes 'liza' (Liza Minnelli).
'to return' is a reversal indicator.
'in' means one lot of letters goes inside another.
'may perhaps' becomes 'brian' (Brian May).
'liza' written backwards gives 'azil'.
'azil' put inside 'brian' is 'BRAZILIAN'.
'getting' acts as a link.
(Other definitions for brazilian that I've seen before include "from South American country" , "Native of Rio de Janeiro, say" , "style 21A 20 [DOWN THERE]" .)
