Buffy's most obvious noted feature was her relatively small size and slender frame, somewhat of an ironic statement given her physical strength and superior Slayer agility. Her hair, although changing in tone, haircut, and hairstyle through the years in accord to fashion and mood, was naturally and constantly blond.

Buffy's other distinguishing features included a bite-mark scar on the right side of her neck. She originally received this scar from the Master.
