The universe of sci-fi Halloween costumes

1. They come from outer space

Alien species, extra-terrestrials and Martians, oh my! Tips: you can go slapstick (little green men with antennas), character (like Giger’s Alien, Avatar or a Klingon) or very creepy (like the grey zombie aliens from X-files). Paint yourself blue, green, silver or lizard skin or go for the classic ‘grey alien’ with large black eyes. A bald cap or short bob wig work great with this theme. Pair it up with a body suit, green dress, overalls, antennas or big foam eye balls around your head. Nanu Nanu.

2. Space oddity

Here’s where you make it all about space. Tips: a burning comet, UFO, use fairy lights, ‘galaxy’ makeup, glow in the dark stars and little foam ball planets and go as the galaxy or solar system, or attach all your old computer parts to a shirt and go as space junk! Astronauts and space cadets from V, Moon, Prometheus, Battlestar Galactica, Event Horizon, 2001: A Space Odyssey and Ellen Ripley. Or, rule them all and go as the president of the galaxy, Zaphod Beeblebrox.

3. Mad scientists

Secretive, corrupt and sometimes mutated by their experiments, here’s where you put the science in sci-fi. Tips: a mad scientist costume can be as simple or complex as you make it – zombie it up, add on some mutated body parts, build in a chest burster from your lab coat, add on a name tag, Area 51 badge, face mask, vials & syringes, or pair up with a friend for an alien autopsy scenario costume.

4. Superheroes

Here’s where you get to save the universe! The superhero theme is really fun for group costumes and the options are endless here. Tips: characters from X-Men, Hell Boy, Flash Gordon, Green Lantern, Fantastic Four, Guardians of the Galaxy, Riddick, Blade Runner, The Matrix, Tron and Mad Max.

5. The truth is out there!

Galactic and supernatural exploration results in a whole crazy following and even makes for pretty cool jobs. Tips: time travellers like Doctor Who, experts like Men in Black or Mulder & Scully from X-files (don’t forget to add a name tag), Not a pro? Then dress as a crazy hillbilly ‘believer’ with a probe still in tow, or pop on some simple aluminum foil hats to stop the aliens from reading your mind.

6. Man vs Machine

At some point the robots are going to take over, right?! It’s that kind of tech-noir paranoia, plus a decent level of ‘kick-ass’, that make this a fun theme to go with for Halloween. Tips: cyborgs, androids and robots and characters like Cylons, Iron Man, Robocop, Terminator, Predator and The Borg. Elements of biopunk, dieselpunk, cyberpunk and steampunk styles (like goggles and Mad Max gear) work really well. Use old electronics, tubing, computer guts & wires to create cyber armour, a bionic arm or half machine face.

7. Space goddess

It wouldn’t be Halloween if there weren’t a few sexy tips for those looking to show some more skin – and there are plenty of (littler) costume options. Tips: characters like Barbarella, Mystique, Jabba the Hutt slave girls (or Princess Leia in her gold bikini), Pris from Blade Runner, black leather assassin Aeon Flux or ‘Six’ in her red dress from Battlestar Galactica. For an effective space girl put on a coloured bob wig and short 60s style dress (a la ‘Ursa Minor’) or slip into a sleek silver body suit and strap on your matching pew-pew gun (homemade, or just spray paint a water pistol!).

8. Retro futuristic

A bit abstract but this is sci-fi at its most stylish. Tips: characters that loosely fit into this are Barbarella, the robot from Metropolis or the Martian Girl from Mars Attacks. To go for a really retro futuristic look, you need to combine high fashion with futuristic elements. Lady Gaga meets Tron? Gear that really works with this theme is silver clothing, all sorts of hoops, and asymmetrical metallic shapes.

9. Star Wars

Star Wars movie costumes are plenty, plus they’re easy enough to score online or at the party shops. Tips: the most popular are Storm Troopers, Darth Vader, Kylo Ren, Darth Maul, Princess Leia, Rey and Boba Fett. Go a little off that beaten path, and there are even more costume options. Think Padme Amidala, Jawa, X-wing fighter, Twi’lek slave girl, Obi-Wan, C3P0 or – if you’re up for a warm night and sore throat the next day – Chewbacca!

10. Star Trek

The classic Trekkie uniform is an easy and always effective look, even if you don’t add makeup or a wig. Tips: for the next level, aim for uniformed characters like Worf, Spock, Seven of Nine or Geordi la Forge. There are also races of aliens from this series which make for amazing costumes, though most need some more makeup work (but, that’s what YouTube’s for!). Think Andorians, Romulans, Ferengi, Nibiru (amazing group costume!), characters like Jaylah or the Borg Queen, or one of those green ‘alien’ girls from the original TV series.

Tips on where to get materials

Silver material: don’t get the insulation stuff – this does not have to be expensive. Head to the bulk material shops or go for the thicker sun or snow-blocking material. If you’re in the Netherlands, ‘Action’ sells an anti-frost and snow blanket for just 1.50 euros (180 x 70).

Overalls: basic overalls can be transformed into astronauts and space cadets – just add a logo or name tag. Add a belt with some weapons or random blacked out or painted items. Cheapest spot to get green, grey or black overalls is usually at the Army Thrift shop (‘dump’ in Holland). For white, check medical supply shops for those thin hazmat style overalls.

Eyeballs, planets and silver spheres: foam balls are the answer here! You can also use googley eyes for the Martian effect, and stick-on glow-in-the-dark stars for a galaxy.
