To tell the truth, it is only a fiction invented by Japanese entertainment novelists and Manga artists in recent several decades.

A kind of fantasy like Startrek made in the U.S.

By the way, normal type (not totaly fiction, not s**y) ninja wear is often called "Kuro Syouzoku"  (black wear) or "Ninja Syouzoku" (ninja wear), but it is also disputable that if real Ninja in old days wore it.
