Dance jacket (6)
I believe the answer is:
bolero
This clue is a double definition.
'dance' is the first definition.
(bolero is a kind of dance)
'jacket' is the second definition.
(bolero is a kind of jacket)
(Other definitions for bolero that I've seen before include "Spanish dance; Ravel's best-known work" , "Woman's short jacket" , "Ravel orchestral piece" , "Spanish dance and short open jacket" , "Upper garment or music piece by Ravel" .)
