"Geek chic" refers to a minor fashion trend that arose in the mid-2000s in which young individuals adopted stereotypically "geeky" fashions, such as oversized black Horn-rimmed glasses, suspenders/braces, and highwater trousers. The glasses—worn with non-prescription lenses or without lenses—quickly became the defining aspect of the trend, with the media identifying various celebrities as "trying geek" or "going geek" for their wearing such glasses, such as David Beckham, Justin Timberlake and Myleene Klass.

By the late 2000s this gave way more to fitted and vibrantly colored clothing, with men wearing skinny jeans as influenced by the Hyphy and Jerkin' movements.
