Fashion expert Choo-Choo shows Dan Soder how to avoid the biggest fashion mistakes for summer. First off, ditch the tank tops, or at least keep them in the gym. Instead, consider lightweight cotton button-down shirts to keep as cool as you'll look. Bulky cargo shorts are another common mistake, so swap them out for a pair of clean looking flat-front chinos. Finally lose the long tube socks and get some no show socks to keep the heat off your feet.
