If you want to stand out at the finish line of just about any race, then why not wear your insides on your outside with the help of one of these freaky-but-cool 'muscle' skin suits! Created by Tomasz Pietek, a Polish graphic designer and keen amateur cycle racer, the suits come in a variety of different styles and cuts, although all feature the creepy-looking, yet anatomically correct muscles as an eye-catching design. It took Pietek months of studying anatomical atlases to get his design down. He says the suit is popular among athletes, performers and health professionals, as well as the odd person simply looking to dress up for Halloween. Check it out!
