She is two to three times taller than Dexter and has peculiar body proportions; a minuscule torso with a large head and gangly limbs, similar to a ballerina's. To complete the ballet look, she wears a rose/brink pink colored small tutu, white pantyhose and pink ballet pumps, which usually create a "squishy" noise while walking. She has a similar personality and hair color to her father. For sleeping she wears a pink nightgown, and she wears her hair down. For swimming she wears a pink one-piece swimsuit and a pink swimming cap with the initial 'D' on the front. She has fair skin, blue eyes and long blonde hair in pigtails.
