Hello, I'm sorry for your misunderstanding, but I was replying to the "501st drawing the line in the sand." A custom costume might be a Rubies costume that's been dyed green, wearing tennis shoes and a face mask instead of a helmet.
I LOVE to see custom Mandos, it'd be pretty boring to only have Bobas and Jangos around. Marrow Sun's heavy Mando helmet is pretty sweet, great for a custom, typical chest armor can also be changed and etc.
Customs = COOL!
Customs in the 501st = Not Cool.
