Questions accessories needed for ballet? (5)
I believe the answer is:
pumps
I believe this clue is a double definition.
'questions' is the first definition.
(as in to pump someone for information)
'accessories needed for ballet?' is the second definition.
(ballet shoes)
(Other definitions for pumps that I've seen before include "Dancing shoes - may be manned!" , "footwear" , "leading questions" , "Forces liquid to move; light shoes" , "Plimsolls" .)
