More than 10,000 athletes from 200-plus countries will march in the Parade of Nations. The U.S. delegation will be wearing berets and somewhat controversial Made in China suits by Ralph Lauren.

Two years ago, she was forced to undergo gender testing after opponents accused her of being too masculine.
Don't Miss: The Olympic men's marathon is always good for some drama. Back in 1908, the first time London hosted the Olympics, the iconic image was of staggering Italian marathoner Dorando Pietri being helped over the finish line by British officials.
