Arrogance of man averse to keeping uniforms apart (7)

Ross

I believe the answer is:

hauteur

'arrogance' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for hauteur that I've seen before include "Overbearing arrogance" , "Nose-in-the-air pride" , "Proud disdain" , "Lofty pride, looking down on others" , "Proud superior attitude towards others" .)

I've seen this clue in The Guardian.
