This week, the designers compete to have Kelly Osbourne wear their look at an upcoming red carpet event. The challenge requires them to give a nod to punk in their designs -- and forego using any black, which proves challenging for most. They meet designer Chris Benz, known as "The Prince of Color," who gives feedback on creating memorable red carpet looks.

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.
