Want to be “extra” this Halloween? Go extraterrestrial with an out-of-this-world DIY alien costume. These ideas work for kids, adults, women, men, and even babies. And you can go all out or just get crafty and make an alien headband (complete with googly eyes, of course!).
You can go old-school movie monster and create a retro Martian look (think: lots of green, including makeup, hair, clothing, and antennae). Or, opt for a more modern space-age version (use plenty of silver or gold metallic materials, glitter, and face paint). It’s an easy costume to pull off—even if you need a last-minute Halloween costume—because the interpretation is all yours.
Whether you want to embrace your inner DIY crafter or you prefer the store-bought route for your Halloween costume, we’ve rounded up some fun and creative takes on outer space and its alien inhabitants. Here’s how to make your very own version of an alien costume—it's a perfect Halloween costume for women, Halloween costume for men, or Halloween costume for kids—that will outshine any others in the galaxy.
