Some countries have decided on their flag bearers and some, like the US, have yet to decide who will bear the flag for the nearing 2016 Olympics.
Voting is still open for the last week before the opening ceremony to be held at Rio de Janeiro, Brazil on August 5. Announcement will be made on August 4.
Polo Ralph Lauren and the United States Olympics Committee, though, have already unveiled this week the opening ceremony parade uniform of the US team, as well as the flag bearer jacket.
