DC Comics experienced it's first big reboot following the events of Crisis on Infinite Earths, which aimed to clean up the messy DC multiverse and reintroduce popular characters like Superman and Wonder Woman with newly updated origins. John Byrne was responsible for introducing the new Superman in the mini-series Superman: The
Man of Steel.
While Superman's costume retained the same look overall as the original, there were some subtle changes that made this the best Superman costume. The blues and reds were darker, his cape was now draped over his shoulders instead of hanging off his back, and the "S" shield was at it's broadest, spread entirely across Superman's chest.
