Calling all model hopefuls: Express needs your help to pull off a record-breaking runway show.

On Saturday night (July 23) the retailer will have its holiday 2011 fashion show in Times Square, but first the runway will be open to the general public as the company attempts to break the Guinness World Record for the most people walking a catwalk.

From 9 am to 6 pm, anyone who drops by to give their best walk will receive an Express T-shirt that says, “I was a model for a minute," a picture of themselves striking a pose and a chance to win a $250 Express gift card. Of course there’s also the chance to make history: A Guinness rep will be on site to keep a count of all catwalkers. The current world record to beat was set by Galeries Lafayette in Paris in 2010, when 521 people walked a runway.

Channel your inner supermodel and get ready for your close-up!
