Sue is a young girl who has green eyes and waist-length blonde hair. she has an ahoge-like strand that curls from the top of her head. She is usually shown to be wearing a pink dress adorned with red ribbons and similarly colored gloves. She also wears a black necklace/choker, black stockings and dark red shoes. sometimes (especially when traveling), she wears a puffy pink hat with a red visor.

However, when seeing people she does not know when they come to visit her estate, Sue wears a classic pink princess like dress, which still bears similarities to her everyday wear. However, she does not wear gloves, instead wearing a tiara.
