Given the talk for ‘comic book’ accurate costumes in superhero media, recently there’s a fabric that exposes visible muscles and it’s a combination of spandex and micro-modal (some breathable fabric generated from tree bark or something). It could help alleviate wearers whenever they do any heavy physical activity.
It’s the ideal superhero fabric made flesh but because it’s so skintight it could get mistaken for body paint. It could even expose the very thing superhero comics have successfully circumvented for most of the part. From my experience wearing tights, it’s more useful for moving out and about but it’s usually stuff that’s better off paired with less revealing garments when outside of athletics and dance.
Either that or superheroes should go the way of Jojo’s Bizarre Adventures for fashionably flashy outfits.
