Please tan entire bust (9)
I believe the answer is:
entertain
'please' is the definition.
(I've seen this before)
'tan entire bust' is the wordplay.
'bust' indicates an anagram.
'tan'+'entire'='tanentire'
'tanentire' anagrammed gives 'ENTERTAIN'.
(Other definitions for entertain that I've seen before include "what the party host will do" , "Play host to" , "Welcome" , "Keep in mind" , "Think about" .)
