about the head protector, a few things. First, you need to buy one and modify it. His headband in the anime, which is I gues the version yo are going for, is black. I recommend the same silky material they have for the headbands. You then need to actually detach it and reacttach it to the black cloth.from his head are hanging two straps. ONe has a little latch on it.
If you want to go all the way, I know a place that right now, because of Halloween has his eyes on sale.
The contacts rock but you can't see very well with them, as they are just for costumes. They look amazing, though.
There is a lot of speculation with the Jacket........ I need to talk to a few people I know who are professional Japanese Naruto cosplayers (their actually is a webpage), they have some amazing costumes and have cosplayed EVERY Naruto person possible, and they did it a long while ago, too. The one person is the best Gaara I have ever seen, and is a girl, she just ROCKS, and I kind you not is too cool.
If you need any pics or help, just pm me,
(the creator of the Kakashi and Sasuke Sharingan contacts) hehe, it's my one clame to fame in Naruto that I designed them
and got them made.
