👶 Alien Costumes for Kids

Kids love everything to do with outer space, and at Disfrazzes we know it. Our range of alien costumes for boys and girls includes comfy, safe and colourful outfits. From padded suits that resemble alien bodies to costumes with wings, tentacles or space helmets — there's something for every little space explorer.

Many of our models use soft-touch fabrics and hypoallergenic materials, ideal for hours of playtime. We also offer sizes from age 3 to 12, making it easy for siblings or cousins to coordinate their looks. Whether it's for Carnival, Halloween or a themed birthday party, these costumes are always a hit.

What Kind of Alien Costume Do You Need?

Group Alien Costumes: Perfect for Teams and Stag Parties

Planning a stag or hen do, a corporate event, or just a group night out? You’ll love our alien costume packs designed for groups. We offer coordinated sets for groups of 3 up to 20+ people, with designs that vary but follow a shared theme.

Mix and match astronaut costumes with alien outfits, or stage a multicoloured galactic invasion. Plus, if you're organising the group, we’re here to help — just contact us at grupos@disfrazzes.com for personalised assistance and special pricing.

Martian Costumes for Halloween and Carnival

The universe is endless, and so is our range of Martian costumes designed for the most anticipated events of the year. For Halloween, the darker, creepier designs are the favourites: aliens with glowing eyes, monstrous mouths or distorted bodies are part of the line-up.

For Carnival, we go for brighter, funnier styles – some even glittery! Whether you want a friendly alien look or something spooky, we have models with prosthetics, capes and metallic fabrics. Many of our costumes are inspired by films like Alien, Star Wars or Guardians of the Galaxy, making them perfect for film fans and children alike. Don’t forget the alien costume accessories — every great outfit needs a helmet, laser gun or (cardboard) spaceship!

Alien Costumes Available in Plus Sizes

At Disfrazzes we believe that the perfect costume has no size limits. That’s why we offer a special category of plus-size alien costumes. From XL to 3XL, our designs are made for comfort, without compromising on quality or style. No more worrying about tight belts, restricted movement or short trousers.

Both men and women will find fun, modern options in this section — with the same finishes and detail as every other size. And if you’re not sure, just check our size guide or contact us. Dressing up should be fun for everyone, no exceptions.

How to Choose the Best Alien Costume

Buying a costume shouldn't be difficult, but we know that with so many options it can be hard to decide. That’s why Disfrazzes is here to help you choose the perfect alien costume. First, think about the event type — is it formal, school-related, fun or spooky? That will help you decide whether you want a classic or bold look.

Second, consider the time of year. In winter, opt for layered or thermal models; in summer, go for lighter fabrics.

Third, check what accessories are included: some costumes come with everything (mask, gloves, boots), while others need a few extras.

Finally, read customer reviews and feel free to reach out to our customer service if you’re unsure. With Disfrazzes, you get quality guarantee, fast delivery and access to over 200 alien products.
