The designers meet Miley Cyrus and are challenged to create a sexy club look for her using leather, silk, and gold embellishments. Tempers flare when the cast competes to grab hold of the limited materials they are required to use. And later, the designers' creations get scrutinized by Miley's "Momager," Tish Cyrus. Will she be offended by the risqué outfits she sees?

The cast creates "off-duty" rock star looks for singer Carly Rae Jepsen and learns that the winning look will appear in a Glamour.com feature. But before they can begin designing, they must get their ideas approved by Carly Rae's stylist as well as Glamour's fashion news editor. It's a test to see who can handle multiple voices and points of view, and who cannot.

The eight remaining designers must create stage looks for Australian twin sisters Liv and Mim, commonly known as the DJ duo NERVO. The pieces all must incorporate cutting-edge technology like LED lights and fiber optics; however, the real challenge comes when the designers must pair up into teams. Which twosome will learn how to work well together and which will implode? Recording artist Kid Cudi serves as the guest mentor.
