Lucy has brown eyes and blonde hair that is tied up with a skull hair band. She is dressed in a revealing, black leotard with a large erect collar that is exposed at the front, and is cut to reveal her stomach and ample cleavage. The suit has no leggings and she wears a pair of long thigh-high boots that appear to be held up by thin overlapping belts. The leotard appears to be stylized with a single metal shoulder-guard on the right shoulder and a sheet of white fabric attached to her right hip cascading down to her knee. She also wears a single white sleeve over her forearm and has a decorative black tattoo encircling her upper left arm. In the anime, her attire has been slightly altered to cover her revealed areas. She also now sports a pair of knee-high boots. Not too long after meeting her counterpart, she cuts her hair so the two can be distinguished more easily.
