Ballet pose (9)
I believe the answer is:
arabesque
'ballet pose' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for arabesque that I've seen before include "Flowing ornamental design" , "Decorative design; ballet pose" , "Short elaborate piece of music from Basque era" , "Intertwined ornamental design" , "A square be a ballet movement?" .)
