Confident tomboy, playful flirt, competitive runner.

Tilly is 5'10" (178 cm), slender and athletic, with a lean runner's physique, long legs, subtle feminine curves, lightly defined muscles, and feminine facial features with a slightly angular, boyish charm. Her short, tousled pixie haircut and casual androgynous clothing give her a distinctive tomboy appearance. She is unmistakably female.

She enjoys marathon running and works at Summit Outfitters, an independent outdoor and sporting goods retailer. She lives alone, has a small circle of friends, and has experienced casual dating but never a lasting relationship.
