Fashion Star is an American reality television series on NBC, created and executive produced by E.J. Johnston, James Deutch and Rick Ringbakk which focuses on fashion design and is hosted by Louise Roe. It was hosted by Elle Macpherson in the first season. The contestants compete with each other to create the best clothes and are restricted in time, materials and theme. Their designs are judged, and one or more designers are eliminated each week.

On May 11, 2012, NBC renewed Fashion Star for a second season.^[2] Season 2 premiered Friday, March 7, 2013.^[3] On July 27, 2013, NBC canceled Fashion Star after two seasons.^[4]

Fashion Star features unknown designers competing for a chance to have their creations bought. Each week, the contestants work with mentors Jessica Simpson, Nicole Richie, and John Varvatos in designing their creations, shopping for materials and overseeing production. They then compete in a fashion show during which they display their work to the three buyers: Caprice Willard of Macy's, Terron E. Schaefer of Saks Fifth Avenue and Nicole M. Christie of H&M in season one, and Erika DeSalvatore for Express in season two. Any designer whose clothes are not purchased that week is up for elimination from the show. The mentors, who also serve as judges, save one unsold contestant each week. Then the three buyers choose which of the remaining unsold designers is sent home.^[5] At the end of the season, the three remaining contestants must create separate showcases of three garments for each retailer. Whoever meets the needs of the three retailers will be named "Fashion Star" and will receive a capsule collection worth $6 million within each store.^[6]

In season two, there were several changes from the original format. Compared to the first season where the mentors coached all the designers, the mentors Jessica Simpson, Nicole Richie, and John Varvatos focused on 4 designers each. Another change was Elle Macpherson leaving her hosting duties, though still serving as one of the show's executive producers. She was replaced by Louise Roe. Also, H&M was replaced by Express as one of the buyers, represented by Erika DeSalvatore. The prize was also reduced from $6,000,000 to $3,000,000. The mentors would choose two designers to face elimination with the buyers voting to eliminate one designer.
