Affectations (5)
I believe the answer is:
poses
'affectations' is the definition.
(pose is a kind of affectation)
This is all the clue.
(Other definitions for poses that I've seen before include "Posse (anag.)" , "Sits for artist" , "Sits (for artists)" , "Strikes attitude, maybe for photo" , "is ready for photo" .)
