Another day, another fashion reality show. In this case, that show is 24 Hour Catwalk, a new show from Lifetime that will be hosted by Alexa Chung and judged by designer Cynthia Rowley, writer Derek Blasberg, and fashion publicist James LaForce. So, how will it work? In 24 Hour Catwalk, four designers will be asked to create a three-piece collection within, yes, 24 hours. First, they will compete in an opening challenge, before being whittled down to two. Then, they will have just one day and the opinions of a sewing team to deal with before presenting to the judges. The prize will be $10,000 in cash. Excited yet? Click inside to watch a preview video and make sure to tune in on January 10 when the show premieres.
