Project Runway

In the Season 4 premiere, Heidi Klum and Tim Gunn meet the anxious group of contestants in New York City’s Bryant Park, where finalists will showcase their final collection.

The designers are visited by a surprise guest judge and are charged with pairing off and creating a look based on the "BITTEN" line.

The designers are asked to design menswear for football great Tiki Barber. A gaggle of male models invade the workroom and flummox most every designer.

The designers must create a fashionable, current look based on out-of-date trends. In addition, they have to team up in trios and ensure their looks come together in one cohesive.

The designers re-style the outfits of 12 women, all of whom have lost a significant amount of weight.

This week brought the designers to the Hershey's store in Time Square, New York. Tim told the designers that they would have to grab whatever they could as raw materials.

It's back to high school this week as the designers helped their student models get ready for prom. All of the designers worked with their teen clients, and clients' mothers.

The models took a trip to the salon before being matched up with the designers. Heidi charged the designers with creating avant-garde designs inspired by models' hairstyles.

Tim takes the designers on a field trip where they were faced with clotheslines of Levi's denim. Their challenge? To create a look that captures the spirit of the 501 legacy.

This week's challenge was to create an outfit for the WWE Divas to wear in the ring. While some designers had a field day, others found the challenge more challenging.

15 Season 4 designers returned for a reunion filled with laughter and tears. Each designer revealed who they think will win Project Runway, and America revealed their Favorite.

Tim travels from coast to coast to visit the four remaining designers as they work on their final collections. Finally, all of the designers reconvene back in Manhattan.

After critiques from Tim and final preparations, the three finalists headed to Bryant Park for a once-in-a-lifetime experience. Who will take home the title and the prizes?
