Front of shirt can have any variation of caps or lower case (e.g., BRACE YOURSELF or brace yourself etc.), and an interesting graphic, whether it's a character or braces or something else fitting. We would love to see lots of different ideas. Something edgy, this shirt will be targeted at young kids and teens, aimed at raising brand awareness driving them and adults to a mobile website.
