"24 Hour Catwalk" is just one of many fashion design shows on cable. But this show has a bit of a twist -- the designers have just one day to come up with their creations. Each episode, four designers are given an opportunity to create their own line ... in one day. After a first cut challenge and elimination, the competition is whittled down to the two finalists. Working with the show's opinionated sewing team, the contestants are tasked with creating a themed collection for their own star-studded runway show. They then prepare to showcase their three-piece collections for the three-piece judging panel: designer Cynthia Rowley, fashion editor Derek Blasberg and publicist James LaForce. The designer who is declared the winner wins a $10,000 cash prize. British TV host and model Alexa Chung hosts.
