Lilynette is a young-looking female Arrancar. Her outfit consists of shorts, arm-warmers, a revealing vest with a high collar, and thigh-high fur-lined boots. Her Hollow hole is positioned in the center of her stomach. The remainder of her hollow mask is the form of a helmet with two horns on the top of her head. The left horn looks as if its been cut off, and the left half of the mask covers her left eye. Her right eye is light pink and she has green hair.
