How can I achieve a comic-accurate Spider-Man costume for cosplay?

Start with a high-quality base suit in vibrant red and blue. Focus on the mask: 3D printing or sculpting a mask with the correct angular features is crucial. Add a crisp white outline to the webbing using fabric paint or vinyl. Consider using a thinner, more flexible material for the suit to allow for dynamic posing. Finally, pay attention to details like web shooters and gauntlets, aiming for a stylized, comic-book aesthetic.
