The 20-episode pick-up was announced by Marjorie Cohn, Nickelodeon's executive vice president of development and original programming.
The series stars Keke Palmer as 15-year-old True Jackson, head of the youth division of a major fashion label.
Cohn lauded Palmer as "an extraordinarily talented actress" who inspires people and is someone to whom people can relate.
"Her star quality, coupled with a dynamic cast and funny, compelling storytelling, has been a winning combination," Cohn said in a statement. "We are thrilled to be bringing this successful series back for a second season."
