Coquettes; improvises (5)
I believe the answer is:
vamps
This clue is a double definition.
'coquettes' is the first definition.
(vamping is a kind of coquetting)
'improvises' is the second definition.
(I've seen this before)
(Other definitions for vamps that I've seen before include "Improvises crudely (mus.)" , "Improvised accompaniments" , "Extemporises musically" , "Seductive women" .)
