Brittany Mahomes just delivered a lesson in festival dressing. Mahomes, 30, attended the annual Stagecoach music festival on Friday, April 24, making a serious style statement in a white, cap-sleeved corset and barely-there ruffled, lace shorts. She completed her 'fit with a silver pendant necklace and belt, coordinating with her ivory cowboy boots. For glam, Mahomes styled her signature blonde tresses in loose waves that she topped with a black cowboy hat.
