It is hard to get even one costume on a list like this, but somehow, Spider-Man managed to show up on this list twice! It all started when a fan named Randy Schueller thought it would be a cool idea if Spider-Man had an alternate costume that he could wear. He wrote in to Marvel with the idea and, since this was back in a day when Marvel still accepted submission ideas from the public, Jim Shooter bought the idea from Randy for a little over $200. Tom DeFalco then worked with Randy for a bit on trying to turn the idea into a Spider-Man issue but it never quite came together. A couple of years later, Shooter was trying to think of major changes to be made in Marvel's Secret Wars event and he thought back to the black costume idea.
If you talk to many comic book fans that entered puberty in the ‘90s, they might list Gambit as the cause of their sexual awakening. Maybe it was the Cajun accent? Or perhaps it’s the dark, red eyes? Either way, Gambit will go down as one of the all-time sexiest characters in the Marvel Universe. The character is one of the few on this list with a costume that covers almost his entire body, down to just leaving his face and hair exposed. This modesty doesn’t stop Gambit from being a character that’s known for his sex appeal.
