Project Runway champ Seth Aaron Henderson is already a little nervous about capitalizing on the buzz surrounding his big win this past spring.

For more on the "adrenaline rush" he felt when Heidi Klum told him he won, his plans for a new ready-to-wear line, and his fashion solution to what he deems "the biggest problem in America," watch the video above!
