Short open jacket (6)
I believe the answer is:
bolero
'short open jacket' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for bolero that I've seen before include "Jacket not covering waist" , "Rob Leo of his short jacket" , "Short jacket or music by Ravel" , "Arrange to rob Leo during the dance" , "Steps" .)
