I think we're avoiding the obvious issue. He's got a serious case of penishead going on here.
Honestly, translating the Flash's costume directly to live-action is misguided. It only looks good on the page, and it doesn't have the benefit of years of live-action portrayals and the resulting audience acceptance that Superman's has. They should've gone more down-to-earth, Jack Knight-ish on this one. Aviator goggles and cap, maybe. Something form-fitting and wind-resistant like a Euro motorcycle jacket. Things that convey speed without looking hopelessly out of place or dorky.
