I had my glossy white tk called a sandtrooper
I had my sandtrooper called a snow trooper ( the little boy jumped in and corrected his mom at that point)
I had my tk called captain Rex ...
I had my friend in a shadow tk called Darth vader
I had my friend in a magma trooper called a red Darth vader (face palm). And an emperors guard.
I have only worn my officer once, but it was at a con and people knew what I was...everyone kept making vader motions and I had to go around choking . I ended up in the local paper correctly identified as an imperial officer as well. I figured I'd be called a nazi a lot but in that con people knew what I was at least.
Thankfully when I am in vader all I hear is darth vader Darth vader Darth vader....
