Dressing for dance (5)
I believe the answer is:
salsa
I believe this is a double definition.
'dressing' is the first definition.
(I've seen this before)
'dance' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for salsa that I've seen before include "Spicy tomato sauce" , "Latin American dance - spicy Mexican sauce" , "Latin American dance music" , "Dance or a dip?" , "Hot dance - hot sauce" .)
