It Girl" was originally slang for a beautiful, stylish young woman who possessed sex appeal without flaunting her sexuality, when the phrase originated in British upper class society around the turn of the 20th century.[1] An early literary usage of the term "it" in this context may be traced to a 1904 short story by Rudyard Kipling: "It isn't beauty, so to speak, nor good talk necessarily. It's just 'It'."
