York is a young-looking woman of incredible size, standing twice the height of Brook. She has long and wavy blonde hair, aqua eyes, and patches of freckles under her eyes. Her mouth is very broad, and she has rosy, chubby cheeks. She wears a purple top cut off just below her breasts with her designation Punk-06 written on the front. 
When she eats a lot, she becomes morbidly obese but can instantly return to her original figure after going to the bathroom.
