Last week’s episode of Project Runway All Stars found quirky designer Mondo Guerra in the winner’s circle again, this time with an item worthy of Nanette Lepore’s approval.

The result of a runway challenge aimed at maximizing profit while working within a budget, Mondo’s dress combines five different prints and fabrics to create a playful smock appropriate for casual days and flirty dates alike.

Not surprisingly, The Mystery Dress (shown left), sold out almost immediately. But it is currently available for pre-order on nanettelepore.com, shipping again on May 15th.

Retailing for $298, all proceeds from this garment will benefit the Save the Garment Center organization in New York City. Order yours here.

In the meantime, you can snatch up some of Mondo’s other items in his online shop.

Project Runway airs Thursdays on Lifetime at 10:00 p.m.
