The Project Runway alum happens to be the youngest winner to come out of the hit reality competition show. Since his 2008 victory, he has also become the most successful. Although some of his runway looks aren't quite wearable, his love of high-drama, fantasy-driven collections — which always seem to include lots of tulle, ruffles, and eclectic fabrics — have kept people interested. Plus, he works overtime, designing everything from Payless shoes to Victoria's Secret makeup to household sponges to create a "fierce" brand.
