Kelsey is fairly short when compared to her friends Craig and J.P. She has peach skin, light red hair tied into a bun at the back of her head, and thick, dark red eyebrows.
Kelsey wears a blue-gray T-shirt with a heart on it, and also wears pink shorts. Her shoes are green and have a white bottom. She has a dark blue cape that she wears around her neck.
Kelsey is very dramatic, in that she often narrates her life in her head in a style akin to theater.
