A new Marvel movie theory helps explain the origins of Spider-Man’s various costumes. While not huge, there is a sort of plot hole surrounding the creation of Spider-Man’s suits, particularly in the movies starring Tobey Maguire, Andrew Garfield, and most recently Tom Holland’s Spider-Man in the MCU. While they each start out with more homemade suits that do look like they could have been made by a teen from Queens, they each end up with fantastic costumes they supposedly made themselves by hand.
In the Sam Raimi Spider-Man trilogy, Tobey Maguire ends up creating an incredible suit with reflective eyes and raised webbing textures. Andrew Garfield’s Peter Parker does the same after initially wearing a ski mask, hoodie, and sunglasses. Tom Holland’s Webslilgner also had a more basic getup with a sweatshirt and goggles before Tony Stark’s Iron Man made his more official suits, though he ended up sewing his own impressive Spider-Man suit at the end of No Way Home. Keeping all three in mind, one has to wonder where Spider-Man got his impeccable sewing skills.
As seen on both Reddit and Tumblr, it’s possible that the radioactive spider that bit Peter Parker and gave him all of his extraordinary powers also gave him such a great knack for sewing. This would not be unlike the natural weaving skills spiders possess to create their webs and nests with impressive levels of detail and intricacy. If true, it would certainly help explain how each of the live-action Spider-Men ends up having such incredible costumes.
This same theory could also be used to help explain how Peter Parker came up with his web fluid formula as well as his impressive ability to swing and web up various traps and tools as needed. Essentially, the idea is that Peter Parker also gained the proportional weaving ability of a spider, not just its strength, agility, and ability to wall-crawl. Again, Spider-Man creating a comics-accurate costume as he does on the page is not the most egregious plot hole, though this theory definitely provides a fun and creative solution that’s in line with his spider abilities.
As seen in the comics, Spider-Man’s sewing abilities aren’t ever explained in great detail, though it seems to be something Peter Parker isn’t a huge fan of doing especially in his early career. There’s even an instance in which Peter wishes he could just reveal his secret identity to Aunt May so she could help him fix his costume. Likewise, Mary Jane helped fix Peter’s suits in the Ultimate Spider-Man comics. However, the original Spider-Man and His Amazing Friends cartoon did show Peter Parker having books about sewing in his room, suggesting that it was something he learned so he could specifically create his first costume as a new superhero.
It’s worth remembering that Peter Parker is also a genius in his own right, so making a detailed costume after creating his own web fluid and shooters would arguably be easy enough. However, there’s no denying that the costumes seen in the Spider-Man franchise do require a certain suspension of disbelief. This is especially true combined with the truth that all the live-action Peter Parkers with their low incomes and resources made their final suits themselves.
