STAGE TUBE: PROJECT RUNWAY ALL-STAR Michael Costello Designs Winning Dress for Miss Piggy

The MVPs from past seasons of the Emmy(R) Award nominated series PROJECT RUNWAY are being judged once again on Project Runway All Stars, which airs Thursdays at 9:00pm ET/PT on Lifetime. On last night's episode, Miss Piggy joined the judges panel and gave her critique of the competitior's designs. Contestant Michael Costello's dress for the Muppet star was chosen as the episode's winning design.

Thirteen of the show's most talented and memorable designers have come back to the catwalk to face a brand new panel of discerning eyes with host supermodel Angela Lindvall, world-famous designers Isaac Mizrahi and Georgina Chapman as judges and fashion tastemaker and mentor, Marie Claire Editor-in-Chief Joanna Coles. The designers have already shown what they can do and have created names for themselves since appearing on their seasons but will they have what it takes to impress these fashion elites? They must also show off their fashion prowess to guest judges such as the iconic Miss Piggy, supermodel Miranda Kerr and musician and producer Pharrell Williams, among others throughout the season.
