Clothing for a Spanish dance (6)
I believe the answer is:
bolero
This clue is a double definition.
'clothing' is the first definition.
(bolero is a kind of clothing)
'spanish dance' is the second definition.
(I've seen this before)
'for a' is the link.
(Other definitions for bolero that I've seen before include "Woman's short jacket" , "Spanish dance and a type of jacket" , "Kind of jacket or dramatic music by Ravel" , "Genre of slow-tempo Latin music associated with Spain and Cuba" , "Steps" .)
