"An It girl is a charming, sexy young woman, or one who has just broken into mainstream cinema and attends parties all the time. The reign of an "It girl" is usually temporary; some of the rising it girls will either become a fully-fledged celebrity or her popularity will fade. The term "it boy", much less frequently used, is the male equivalent.
Modern "It girls"
Since 1927 the term has been extended beyond the world of film, referring to whoever in society, fashion or the performing arts was in vogue at the time, including, from the 1960s onwards, singer and Rolling Stones' muse Marianne Faithfull, Talitha Getty, actress and socialite Edie Sedgwick, actress and comedienne Goldie Hawn, 1980s "wild child" Amanda de Cadenet, socialite Tara Palmer-Tomkinson, model Kate Moss, actress and "boho"-queen Sienna Miller, actress from The O.C. Mischa Barton, twins Mary-Kate and Ashley Olsen, actress and socialite Nicole Richie,socialite/actress Paris Hilton, and actress Lindsay Lohan.
The writer William Donaldson observed that, having initially been coined in the 1920s, the term was applied in the 1990s to describe "a young woman of noticeable 'sex appeal' who occupied herself by shoe shopping and party-going" (Brewer's Rogues, Villains and Eccentrics, 2002). At around the same time the term posh tart was coined as a broad equivalent, though this tended to be reserved for those, such as Palmer-Tomkinson and Lady Victoria Hervey, daughter of the 6th Marquess of Bristol, who came from the "higher" echelons of society.
In the 2000s the phrase generally refers to a modified version of the Brewsters quote "an IT girl is a young woman of noticeable 'sex appeal' with rich parents who occupies herself by shoe and fashion shopping and party-going with accompanying media attention as they attend events at well known celebrity night spots, get arrested and spend time in rehab."
