She has brown hair with curls at the bottom, and a light skin tone. Her nose is small and round, with four freckles on it, and she has lashes on the bottoms of her eyes and large hips.

Trivia

 * In "Boss Mabel," a woman waiting on line for Cash Wheel shares the same model, but with a different color palette. This blonde version was also briefly glimpsed in "Dipper vs. Manliness" walking down the street, after Dipper Pines leaves Greasy's Diner gloomily. The original orange shirt woman and the doppleganger make another reappearance together, sitting two rows apart in "Mabel's Scrapbook: Heist Movie" in the theater.
