Fifteen-year-old True Jackson is selling sandwiches and lemonade with her friend Ryan in the fashion district of New York City, when she is complimented by fashion designer Max Madigan, founder and CEO of Mad Style. Max realizes the clothes True is wearing are his designs, but True had altered them to suit her own purposes. Max likes the altered design and hires True to be the VP (Vice President) of his fashion company's youth apparel division. True hires her best friend Lulu to be her assistant after firing Cricket, her former assistant who was upset and bitter about being surpassed in the business by a kid. With Lulu's and Ryan's help, True works to be the best she can be despite various obstacles such as her self-centered co-worker Amanda, who is less than enthusiastic to be working with a teenager, but the truth is that she is jealous of True because of how Max pays more attention to True than he does to her. True sees Amanda as an amazing icon in fashion and eventually Amanda recognizes True as a fashion equal, though she still taunts True playfully on a regular basis.
