Elegance about setter's face (7)
I believe the answer is:
grimace
'face' is the definition.
('grimace' can be a synonym of 'face')
'elegance about setter's' is the wordplay.
'elegance' becomes 'grace' (I've seen this before).
'about' is an insertion indicator.
'setter's' becomes 'im' (I've seen this in other clues).
'grace' placed around 'im' is 'GRIMACE'.
(Other definitions for grimace that I've seen before include "look disgusted" , "Expression of pain or disgust" , "Frown" , "Disgusted expression" , "Contortion of face expressing pain" .)
