What to Wear All a Matter of Money at Olympics

Olympians should have figured out one thing by now: What they can or cannot wear at the London Games has very little to do with their fashion, marketing sense or patriotism, and a whole lot to do with rules, regulations and money.

The overseers of the Olympics are protective of their brand and rings—considered one of the most recognizable logos in sports—and what the athletes wear when they're competing has been tightly regulated.

Take Michael Phelps, for example. He recently tweeted his dismay at no longer being allowed to wear a swimming cap bearing miniature American flags on the front and back.
