Global Beauty Director for YSL Beauty, Tom Pecheux says that glitter is the way to go for festivals because it will look good no matter your skill level. "I really love glitter because it makes you think of joy and happiness," he tells Refinery29. "You don't need to be an expert to wear it. It's easy to put on — could be a nightmare to take off — but it's so worth it," Pecheux says.
