Someone on another forum had posted that uniformed armed people the world over are increasingly beginning to look the same = this uniform could be tweaked to look like until recently the USN uniform (submariners?), Chinese navy, latest British police dressed for "anti terror", US SWAT team and so on. And that may be on to a valid point.
Naval uniforms - globally - look pretty much the same. Double-breasted tunics, gold braid on the sleeves, and white hats for officers; Jean-Paul Gaultier creation for the Ratings (see post above). I'm reminded of the story of an RN officer captured at Dunkirk in full rig who managed to escape during transport and travelled right across Germany to Luebeck, where he stole a fishing boat and got across to Sweden. He stayed in his uniform all the time and no one noticed that he wasn't Kriegsmarine. Speaking German probably helped!
