When she switched to acting, Lee starred in television series such as Premonition (1997), Dal-ja's Spring (2007) and Queen of Housewives (2009), and also founded the fashion brand Miss Dorothy.

[1] In 1992, she became part of the three-member K-pop group 1730 alongside Kim Joo-hoon and Hwang Ho-young; 1730 released two albums then disbanded.

[3][4][5] Lee soon built a reputation for being one of trendiest and most fashionable Korean celebrities (pre-stardom, she previously worked as a stylist for the band Chakra).

[11] Once she entered her forties, Lee felt that her age would be incompatible with Miss Dorothy's target demographic of women in their twenties and thirties, so she left the company and sold her shares in 2012, then donated all the proceeds to charity.

[19] On March 6, 2022, Lee donated 10 million won to the Hope Bridge Disaster Relief Association to help the victims of the massive wildfire that started in Uljin, Gyeongbuk and has spread to Samcheok, Gangwon.
