I'm having trouble figuring out what is on Germany's collar (right in the middle) it's a + shape. Is it an Iron Cross? How would I attach that or is it a necklace/medal?
At this site
the crosses have a pin back, but I don't know how/where it was actually worn or if Hidekaz just designed it there just because. (Wikipedia does say it could be worn on the 2nd button, but the image below looks like its on the very top).
-EDIT- Would you call it the Grand Cross? (ALSO, Wiki says a guy named Göring wore a Grand Cross around his neck in some photos)
