If you missed The Suffers' performance on the Late Show with David Letterman on Monday night, that's all right. The emerging Houston band's live version of "Gwan," off their new EP, is perfectly suited to perk up your morning or shake you out of your post-lunch coma with its infectious groove. Even Letterman himself was notably impressed and ended the show with a ringing endorsement: "If you can't do this, get out of the business!"

One thing that always sets The Suffers apart is frontwoman Kam Franklin's engaging, high-energy style, and for her network television debut Franklin's outfit had her looking as radiant and colorful as ever. For the occasion, the singer picked out a captivating floral frock from Modcloth covered in a pattern of Texas wildflowers, pairing it with a pair of cowboy boots and vibrant green earrings. As a bonus, Modcloth named the dress "I Field Good," a pun on a James Brown classic that surely lent some funky vibes to the performance.

"I knew I wanted something that would represent Texas.... when I saw this dress I knew immediately that it was the one, with the wildflowers on it—I don't know if they're bluebonnets, but they look like bluebonnets," says Franklin. "I like to perform in dresses because I can move around in them. It's all about being comfortable and glamorous at the same time."
