The Undies Suit is a humorous and unconventional outfit for Spider-Man, featuring a tight-fitting, skin-tone bodysuit that mimics the appearance of being in just underwear, complete with a web pattern subtly embossed to maintain the superhero aesthetic. The suit includes a detachable mask with expressive, oversized white eye lenses, and the material has a slightly glossy finish to simulate sweat, enhancing the comedic effect. The design is intentionally simplistic, with no additional armor or tech features, focusing on the absurdity of the concept while maintaining the hyper-realistic texture details of the game's art style.
