Yes I got no idea what cosplay really is, but I guess it can be anything.

Lets say I want to cosplay as one of the people who worked at Unit 731.

hXXp://livedoor.blogimg.jp/toshi_densetsu/imgs/1/e/1e7ab347.jpg thats the image that show their clothes, I am pretty sure there is no color images at all from what happend at unit 731 so we just have to guess what colors they really did have, we can proabably figure out that it was dark clothes tho?

The real question is what material it was made from. My friend sent me this about it:

plastic wasnt arround there
we must know what rainclothes where made off
that will be a step in the right direction
or find out what early american/german biohazard suits where made off
might be rubber/leatherish

We do know that America knew about Unit 731 but dident really care, I think it was because unit 731 did produce some decently good medical data and well.. russian prisoners was used so whatever.

Do you have any leads on how I can maky my very own Unit 731 outfit?
