Alien Halloween Costume Ideas That Are Out-of-This-World Creative

We still don’t know what other life is out there lurking in the universe, which makes inventing your own DIY alien costume a blast! You may immediately think of little green creatures with googly eyes, or silvery, intergalactic extraterrestrials, but who really knows what aliens look like? That’s the fun part of inventing your own an alien Halloween costume–no one can say it doesn’t look real.

You can go old-school movie monster and create a retro Martian look (think: lots of green, including skin, 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—you can even pull it off as 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, best friend Halloween costume, or Halloween costume for kids—that will outshine any others in the galaxy.
