Dignified manner (5)
I believe the answer is:
poise
'dignified manner' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for poise that I've seen before include "Graceful and elegant bearing in a person" , "Elegance" , "Grace; equilibrium" , "Coolness and composure under strain" , "Sang-froid" .)
