In contrast with her friend and foil Jenna, Liz seems to have little interest in stereotypical female interests, such as fashion. In "Blind Date", her "bi-curious" shoes led Jack to erroneously believe she was gay, and set her up on a blind date with his friend Gretchen Thomas, the "brilliant plastics engineer/lesbian". Except when she is pressured to dress more femininely, Liz typically appears in casual, gender-neutral attire. In earlier episodes, she almost always wore plastic-rimmed glasses, though she started to wear them less frequently over the course of the series. Flashbacks reveal that she has worn glasses since she was around four or five years of age. However, according to Jenna in "The Rural Juror", she does not actually need glasses. (Tina Fey also does not need glasses, except to see far away.)
