How has Batman's costume evolved throughout the comic book series' history?

Batman's costume has undergone numerous changes. Initially, it was a more generic, grey suit with pointed ears. Over time, it evolved to the darker blue and grey color scheme we recognize today. The cowl's design has also shifted, with variations in the ears' length and shape, and the addition of features like the sonar and grappling hook. Modern iterations often incorporate advanced technology and tactical elements.
