It's Memorial Day in the U.S., which means you may now wear one of your seasonal wardrobe staples. Just like these folks.
You can run over rooftops in white pants. (see above)
Or you can run up walls....
You can beat up dudes while wearing white pants.
Dressed in white pants, you may slay vampires.
Or, simply, you could just throw a fireball.
Enjoy this first unofficial day of summer, Northen Hemisphere people. And, really, don't take the fashion tips too seriously. White pants are fine any time.
