The knight of Umbar is no doubt given numenorian style garb do to coming form Umbar (Black Numenroians also come from umbar). Why the Betrayer is dressed as he is I know not. I assume it has to do with East = Evil, and his dress is sorta east/middle eastern. Tolkien it is important to note never goes into much detail on the culture of look of the Evil Men From the east, the corsairs/easterling/Muhad/Khandis/Haradrim, their whole look is all Peter Jackson/GW.
