Alien & Astronaut Costumes

How to choose alien and astronaut costumes

Decide whether you are exploring space or invading Earth. Astronaut suits are the friendly side of this collection, while alien masks and Killer Klowns From Outer Space costumes cover the scary side. Both work well for couples, since one can be the astronaut and the other the alien.

Astronaut suits for every age

Adults can choose white, silver and orange astronaut costumes, a women's astronaut costume, or the deluxe teen and adult astronaut suit. Kids astronaut costumes come in Small 4 to 6, Medium 6 to 8 and Large 10 to 12, and Aeromax makes an Apollo 11 style child suit and an orange suit. There are toddler astronaut costumes and baby astronaut suits and buntings too. Finish the look with astronaut gloves, boots or boot tops, which come in white, silver and orange for kids and adults. For more career looks, see occupation costumes.

Alien costumes and masks

For aliens, there are grey alien masks, light-up alien masks, Area 51 and Evil Invader masks, an alien probe mask, an alien mask and glove set, and an alien hoodie dress for women. Kids can pick an E.L. alien costume, Monsters vs. Aliens characters, a toddler alien or an infant alien. Inflatable alien costumes for adults include the Toy Story alien. Small add-ons like alien antennas, blue latex alien ears and an alien shoulder buddy are an easy way to dress up a plain outfit. More blow-up styles are in inflatable costumes.

Killer Klowns and sci-fi horror

Killer Klowns From Outer Space fans can choose Slim and Shorty costumes for adults in Medium to Extra Large, kids jumpsuits in Large and Extra Large, and overhead latex masks with hair. Other sci-fi horror masks include a Mars Attacks Martian, a They Live alien and alien viewer pieces from Nope. See scary masks for more.
