Performer offering bare all-in wrestling? (9)
I believe the answer is:
ballerina
'performer' is the definition.
(ballerina is a kind of performer)
'bare all-in wrestling?' is the wordplay.
'wrestling?' indicates an anagram (I've seen 'wrestling' mean this).
'bare'+'all'+'in'='bareallin'
'bareallin' with letters rearranged gives 'BALLERINA'.
'offering' acts as a link.
(Other definitions for ballerina that I've seen before include "Pavlova?" , "girl from the Kirov?" , "Dancers" , "agile performer" , "Female dancer, could be prima" .)
