Buffy Snooty Patooty

Buffy Snooty Patooty is part of the Maxis-made Snooty Patooty Family, which can be downloaded from the official website for The Sims.

Her bio mentions that she enjoys high tea and is a member of a bridge club, both of which are also mentioned in Cornelia Goth's bio. It is possible that the two are intended to be friends, though characters in The Sims have no relationships outside of their household when first played. Buffy and Chip live together in a mansion on 2 Sim Lane.

She has short brown/blonde hair with a twirl at the top and wears the exact same dress as Bella Goth

Trivia

 * Buffy's dress is identical to the dress Bella Goth wears in most games.
