Performer appearing all bare in movement (9)
I believe the answer is:
ballerina
'performer' is the definition.
(I know that ballerina is a type of ballet dancer)
'all bare in movement' is the wordplay.
'movement' is an anagram indicator (letters move around).
'all'+'bare'+'in'='allbarein'
'allbarein' with letters rearranged gives 'BALLERINA'.
'appearing' is the link.
(Other definitions for ballerina that I've seen before include "Female classical dancer" , "girl on point duty" , "lass good at splits?" , "Danseuse" , "She dances to a rain bell" .)
