In WWII industrious British soldiers made passable German uniforms , to escape with, using only the most rudimentary kit. What can a person with internet for research , modern sewing machine and the will to make a copy of a uniform, do. I could make a very passable helmet out of paper mache' if need be.
Also there is such a thing as IDENTIFICATION and CROSS CHECKING and PHONING FOR VERIFICATION on the part of people. My wife has a set of camo pants, as does my son...please inform the MP'S to come and arrest them
