Repeating the first challenge on season 1 of Project Runway, the designers were asked to create a look using only materials purchased from a Gristedes grocery store.

The guest judge, Austin Scarlett, competed on Season 1 of Project Runway and won this same challenge with a dress made of corn husks.

Tim Gunn drove the designers around the city via a sightseeing tour bus, then provided them with digital cameras to take photographs of their inspiration.

The four groups and their assigned stopovers are as follows: The designers were brought to the Armory Track and Field Training Center by their mentor, Tim Gunn, and were introduced to U.S. Olympian and speed skater Apolo Anton Ohno.

They were given 30 minutes to sketch and draw inspiration from the National Track and Field Museum, after which they were given $150 and one day to complete their designs.

Working in teams of two, designers were asked to make an outfit that could transition from day to night for Brooke Shields's character Wendy Healy on the television show Lipstick Jungle.

The designers were required to make an outfit made entirely out of the spare parts and raw materials from a Saturn hybrid car.

After taking an elevator to the roof of the building, they were instructed to collect as much of the recycled car parts from within the parked Saturn vehicles.

Their challenge was to create a look for her Fall 2008 collection inspired by the movie A Foreign Affair, starring screen legend Marlene Dietrich.

The winning garment was produced in limited quantities and exclusively sold to American Express cardholders, with proceeds going to the CFDA Foundation.

There the designers were greeted with surprise guest appearances of former Project Runway designers and winners Kara Janx, Alison Kelly, Jay McCarroll, Robert Plotkin, Christian Siriano, Daniel Vosovic, & Carmen Webber, who all voted on a winning look.

This episode featured a surprise double elimination & the winner no longer had the advantage of immunity going forward.

Teams: The designers were assigned recent college graduates and were given the task of giving them a fashion makeover to help them enter the workforce.

The guest judge was originally scheduled to be Jennifer Lopez, but she was unable to participate due to a foot injury and was replaced by Tim Gunn.
