7. Stealth Suit
Introduced as part of the "Big Time" story arc which saw Spider-Man create a number of new costumes to take on different enemies, the stealth suit has a lot of qualities which make it right for the next big screen Spider-Man. Firstly, giving Peter the ability to cloak himself would add some interesting new storytelling possibilities for future adventures. Secondly, it would make this version of Spider-Man really stand out in the Marvel Cinematic Universe far more than just a kid in the old red and blue outfit ever would. The fact that it essentially lights up might seem silly on the surface, but designed in the right way, it could look stunning. Plus, you can easily imagine Iron Man thinking up this particular version!
