Lulu Golightly is the older sister in the Silk Cat family of Sylvanian Families, with a younger sister named Tiffany and a younger brother named Toby. She works as a makeup artist and manages the Cosmetic Beauty department at Sylvania's Grand Department Store. Lulu applies makeup with remarkable speed and skill, creating results described as "like magic." Her philosophy centers on makeup empowering individuals emotionally, boosting confidence and happiness rather than just altering appearance.

Lulu shares a close friendship with Stella Chocolate, the older sister of the Chocolate Rabbit family. They often dress up and go out together. Before Stella's first date, Lulu applied makeup at her shop, transforming Stella's nerves into feelings of beauty and confidence; Stella later recounted feeling "on top of the world."

Lulu also mentors younger characters. Visiting Stella's dress shop, she found Tiffany and Stella's younger sister Freya anxious about their first concert. Lulu playfully framed makeup as a "magic spell," applying looks that complemented their dresses. This instantly boosted both girls' confidence and excitement, reinforcing Lulu's belief in makeup's magical, transformative power to make people feel capable and confident.
