Superman #123, by Dan Jurgens and Ron Frenz
Probably the most controversial costume change ever, and one that certainly got media attention, Clark was developing weird electrical powers after visiting Kandor that were making him phase in and out of this world. But thanks to a snazzy new blue suit, he was able to control his powers and, as you can see above, switch instantly from Superman to Clark Kent. Later on thanks to Cyborg Superman, Supes would be split into Superman Red and Superman Blue, who both thought they were the real deal. After a year and much derision, everything went back to normal, and the classic suit reappeared. A largely forgotten era in Superman, it probably gets more recognition because the costume change was shown early on in Morrison's JLA run.
