Working in teams can oftentimes prove more difficult than flying solo. Today, the contestants experienced this firsthand. Brooke Shields, known for her striking good looks and gorgeous locks, took the designers by surprise as today's guest judge. She challenged them to create an outfit for her character Wendy Healy on Lipstick Jungle. All the contestants pitched their designs, and Brooke chose her top six. The chosen designers then picked a teammate from those who were left. In true Project Runway form, there was more in store for the designers ....

Brooke's character on the show is a high-powered movie executive who also enjoys her time out on the town with her girlfriends. Therefore, each team was instructed to create a garment that could easily transition from day to night. The look was to appear office appropriate with an evening-ready twist.

As the designers made their way into the salon and discussed hair looks, they all decided to stay true to Brooke's signature hairstyle -- big voluminous waves.
