Black damn shorts!

Hey guys,

I have scoured the interwebs trying to find 1/6 black shorts. Im wanting to kitbash a Bruce Wayne during a scene from TDKR.

More specifically the scene in which he was trying out his new knee brace wearing a black shirt/shorts and shoes. I can easily find shirts but I am having a fair bit of trouble coming across a decent pair of shorts.

If anyone has any or can point me in the right direction of some that would be fantastic!

Thanks in advance

Magic Cube made an army training set that should work.
