The Ninja Nucleus

Let me start of a subtopic.
You know how different people describe ninja costumes differently.
Well what do you say a ninja costume looks like?
I say it is black to blend in with the shadows.
It is made of cloth and some parts may be light metal for flexibility and speed.
It covers the whole body except the eyes so a ninja can see.
There is a strap over the chest, continued to the waist, continued to the back waist and continued to the back chest, used for holding the katana.
