 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.
