Everything in bear outfit for performer (9)
I believe the answer is:
ballerina
'for performer' is the definition.
(ballerina is a kind of performer)
'everything in bear outfit' is the wordplay.
I cannot really understand how this works, but
'everything' could be 'all' (all things) and 'all' is present in the answer.
'in' is found in the answer.
an anagram of 'bear' is 'bera' which is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ballerina that I've seen before include "agile performer" , "lass good at splits?" , "Female dancer, could be prima" , "Danseuse" , "girl on point duty" .)
