Performer discards attires (7)
I believe the answer is:
artiste
'performer' is the definition.
(artiste is a kind of performer)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for artiste that I've seen before include "professional dancer?" , "Trouper" , "Entertainer, singer or dancer" , "Person playing" , "Attires like entertainer" .)
