Lilly has long grey hair pulled back with a yellow clip, light blue eyes and medium skin. She is mostly interested in Weather. When it comes to Lilly's skill points, she has maximized the mechanical skill and is halfway towards maximizing the cooking, logic, and creativity skills. She has the same facial structure as Esther Tse. According to Lilly's SimDNA in SimPE, her hair was blonde before it turned grey. Sometimes if she is made playable, her PlumbBob will be inside her, instead of above her head. This happens with several other NPCs in The Sims 2.
