This is Catherine Frensky of the Arthur series dressed in a keyhole sweater. A request by  dth1971

Catherine Frensky is the older sister of Francine Frensky.

Catherine is almost the exact opposite of Francine: she likes wearing dresses, is a very responsible person (unlike her sister,) and she really loves to shop. She enjoys reading teen magazines and frequently uses the telephone. Like most sisters, Francine and Catherine go through various fights, like how to decorate their room in the episode "Francine Redecorates" and who gets the last soda; however, despite their arguments, they genuinely love each other. She briefly wore lipstick in one scene of "My Dad, the Garbage Man," nail polish in one scene of "Stolen Bike," and got a pedicure in "Muffy Get Mature," but she usually prefers to keep her appearance natural.
