This Halloween, you plan on having a costume that is truly out of this world. No, seriously — you plan on going as an alien. Since we have yet to discover any otherworldly neighbors, this is the perfect costume idea to let your celestial creativity shine. Whether you go as a glamorous martian in a silver jumpsuit or an adorable little green man, you’ll need some captions for alien costumes to make your posts interstellar.

From TV shows like Roswell, New Mexico to movie franchises like Star Wars, you have so many aliens to choose from. If you’re a Disney lover, your idea of an alien is the “eternally grateful” toys from Toy Story. Get a whole toy box crew together with your roomies, and use one of their infamous lines from the movie for your group pic caption. Another iconic alien is the one Britney Spears channels in her “Oops!... I Did It Again” music video. Get yourself a red jumpsuit like the one she wore in the video, and pair it with some combat boots. Then, learn the choreography for an epic Instagram Reel.

A simple and cute couples costume is E.T. and Elliott from E.T. the Extra-Terrestrial. One of you can wrap yourself up in a blanket, while the other wears a red zip-up hoodie. Though, if makeup is where you really shine, try a galaxy lewk. Record yourself doing a cool transition video for a makeup reveal Reel.

Whether you planet ahead of time or not, you can be prepared for Halloween with any of these 30 alien costume captions to use with your unbelievable snaps.
