Shadow of the Bat re-established the concept. The yellow ellipse was eventually removed in 2000 after a 36-year run and replaced by a larger stylized black bat-emblem, which resembles the one from the Golden Age comics. The ellipse made a comeback in 2021. Other elements, such as the utility belt and the length of the cowl's ears, have been changed by various artistic teams. Basic suit Bob Kane's original sketch of the character was very different from the Batman known today. Kane showed the very first drawing of a character he had first named the Bat, then Bat-Man, to Bill Finger who was the writer he hired to write the first Batman stories. Bill thought that the character looked too much like Superman, so he suggested major changes that would prove to be everlasting to the character's legacy. Finger took a Webster's Dictionary off the shelf, looking for a drawing of a bat, and found one. He then said to Kane, "Notice the ears, why don't we duplicate the ears?" He then suggested that Kane would draw what looked like a cowl, to bring the nosepiece down and make him look mysterious and not show any eyeballs at all.

He also suggested that the color of his bodysuit should be gray instead of red and a pair of gloves were added, colored purple from the start but later changed to blue.

Modern depictions of Batman's suit do not incorporate contrasting briefs, and the character's suit consists of pants without a color change. The Batsuit is also no longer portrayed as a one-piece suit, as the top and pants are separate pieces. The Post-Crisis version of the bodysuit is not constructed from simple fabric, but from fictional advanced materials that gives it resistance to
