Mannequins (6)
I believe the answer is:
models
'mannequins' is the definition.
('model' can be a synonym of 'mannequin')
This is the entire clue.
(Other definitions for models that I've seen before include "Seldom (anag)" , "Exemplars or mannequins" , "Mannequins or examplars" , "Poses for artists" , "Representative forms or patterns" .)
