Everyone knows you are supposed to wear your superhero costume under your clothes, which is probably why Xgen Products has a line of superhero corsets that are ready to wear.
These corsets are officially licensed by DC Comics and you can get Batman, Superman, Wonder Woman and Harley Quinn designs ranging in sizes from small to extra-large. If the base design isn’t to your liking, you can also get a sequin version of the corsets.
If this seems weird to you, consider that the only reason this line is around is because the Super Hero Panties line was a huge success for Xgen Products.
