yeah, good point ^^. i don't have any pix of the whole costume setup, and i'm still missing a back plate and guantlets, but you'll have to trust me that this Custom Mando looks alright.
i still don't know how to put pix directly in the reply, sorry about that....
to give everyone a visual, it's got black underneath, the thigh pouches are gray, the helmet is a repainted Jango helmet, with black instead of the blue-purple. the cape is a silvery gray, and the knees are gray. i'm still messing with my camera (stupid Vivatar) but i'll probably get it fixed soon.
I would say use what ever you like and is comfortable for you. The under shirt that I am wearing is an old paintball Jersey and I am wearing black BDU pants. I have seen alot of cover-alls and jump suits used as well.
