Last night on NBC's "Fashion Star," the remaining designers were challenged to expand their brands by creating clothes outside of their comfort zones. Five of the designers' garments were successful in pushing the boundaries and were purchased by three of America's top retailers: Macy's, H&M and Saks Fifth Avenue.

Celebrity mentors Jessica Simpson, Nicole Richie and John Varvatos helped guide Ross Bennett, Ronnie Escalante, Kara Laricks, Nzimiro Oputa and Luciana Scarabello in constructing their winning creations, which are available online and in stores now. The series, hosted and executive produced by Elle Macpherson, continues the search for America's "Fashion Star" in next week's episode airing Tuesday, April 24 10-11 p.m. ET when the celebrity mentors must decide what each designer will create.

Ronnie Escalante received his second purchase of the competition from Macy's buyer Caprice Willard who also bought Luciana Scarabello's cropped jacket design.

While some of the designers excelled outside of their creative comfort zones, others found it difficult to execute the challenge. Beachwear designer Nikki Poulos struggled with how to properly construct a men's garment. Meanwhile, Barbara Bates had a tough time interpreting boho-chic. Orly Shani, Nikki Poulos, Barbara Bates and Sarah Parrott found themselves in the bottom four and up for elimination. The celebrity mentors chose to save Nikki Poulos. In the end, the retailers decided that Barbara Bates was not their "Fashion Star."

Additionally, viewers will have unprecedented, behind-the-scenes access to each designer on NBC.com's contestant blogs: http://www.nbc.com/fashionstar/about/bios/designers/.
