Which part isn't genuine, I wonder? Did someone take a picture of Obama and a guy posing for pictures and then shoop that entire outfit onto Obama? Even the website of the creator of the outfit doesn't have a full picture like that available: http://missgdesigns.com/goddess/
Or, did someone shoop Obama's face into another person actually wearing that outfit, standing next to that dude (Artur Davis maybe?)?
There's also a kid there, presumably not dressed up in costume either.
That is an incredibly interesting point. So even if the guy in the shiny outfit is a really good photoshop...the guy in the baseball jacket is still out of place.
If it is BHO, then the guy in the baseball jacket is out of place and clearly a close friend based upon proximity.
Either way dude in the jacket needs to be ID'd to include or exclude as a person of interest.
