Spanish dance or jacket (6)
I believe the answer is:
bolero
This clue is a double definition.
'spanish dance' is the first definition.
(I've seen this before)
'jacket' is the second definition.
(I know that Bolero is a bolero)
(Other definitions for bolero that I've seen before include "Spanish dance; Ravel's best-known work" , "Ravel orchestral piece" , "attire" , "Rob Leo of his short jacket" , "Kind of jacket or dramatic music by Ravel" .)
