I wish I could make it but I have no cosplay T_T
First of all an army of 10 is better than an army of one...unless it's the US Army.
Second of all Tanoku, I found the simplest cosplay for anyone to find and use.
1. pick a basic color (red, blue, green, orange, purple, black etc.) all of the clothes are the same color
2. Find a pair of athletic pants
3. find a plain long sleeve shirt
4. Find a plain T-shirt
5. Find a scarf that you can use as a belt
6. Clan or village headband optional.
7. Wear the athletic pants, long sleeve shirt and belt, on the outside.
This trick I found on "how-to wiki"
Put your head through the T-shirt but don't put it on.
Instead bring the back collar over your head to your forehead and the front collar up over your nose, then tie the short sleeves together behind your head. Instant Ninja!
