Millions of Southern Californians dress up every year for Halloween, usually with a cheap costume that only gets worn once. The lifespan of those outfits quickly end in the trash, creating a landfill horror story.

That’s where Heal the Bay’s Halloween Donation Drive comes in. The aquarium run by the nonprofit in Santa Monica is accepting gently used costumes and giving them away for free around the holiday.

The drive will run through Nov. 7.
