'Project Runway: All Stars': Bottom Two Contestants Have One Hour To Repurpose Their Dresses (VIDEO)

It was a first -- and an incredibly high pressure situation for two of the contestants -- on "Project Runway: All Stars." When the judges couldn't decide which of the bottom two designers to eliminate, they decided on an impromptu challenge. It would happen right there on the runway.

The designers were given one hour to deconstruct their dresses and repurpose them into entirely new looks. The judges hoped that this daunting task would help them make their decision. It didn't. Instead, both designers simply blew them away with what they were able to accomplish in that extraordinary situation.

"My mouth just dropped to the floor when both of your looks came out, because for one hour it’s just kind of extraordinary what you’ve done," Georgina Chapman said.

Cynthia Rowley took it one step further with her comment, saying, "I think it’s a hilarious f*ck you to all of us, I’m sorry!"

In the end, Uli Herzner managed to avoid elimination, making it into the Final 3. For Joshua McKinley, it was the end of the road.
