I believe the ones who are wearing the suit tops outside their shirts are from countries that didn't issue long sleeve uniforms.

It is interesting that the commentary does not stop about the beach volleyball uniforms even though it has been an Olympic sport for over ten years with the same uniforms.

I like that they have expanded the options because of the location of the venue (and the weather) because it has allowed increased participation from women in more conservative countries.

It is interesting though because indoor volleyball was played in briefs forever (at all levels including my junior high team) and no one ever said boo.
