A prairie nigger is still a prairie nigger, but that's no excuse not to be dressed up properly when attending high-class events for white people. Any high-class dress is acceptable, but obviously some modifications must be made for a nigger or someone seeing her might get the impression she is attempting to pass for an equal. Therefor, her breasts should be in the open and on display at all times to be enjoyed by white guests at any time or place, and obviously a mere trophy nigger is only there to look pretty, not to speak or voice her thoughts under any circumstances.
If she's a particularly good girl, someone may even offer to breed her, and what greater pleasure and honour is there for a nigger girl than that?
