I searched high and low for a Loki helmet and costume and came up empty-handed. See how I made this DIY Loki helmet and Loki costume for my son. My posts contain affiliate links, which means I may earn money on purchases made.

When creating my family’s costumes for Mickey’s Not-So-Scary Halloween Party, I discovered that while the Marvel Universe was very popular, there wasn’t a single Loki costume or Loki helmet for kids to be found.

I couldn’t get the picture of my boys dressed as Thor and Loki out of my head so I knew I had to make it happen even if it meant creating my own DIY Loki helmet and costume. We are big Marvel fans around here and this had to happen.

I know we don’t have many more years of matching Disney family shirts and costumes ahead of us, so I plan to soak up every photogenic moment.

Creating family costumes was easy for Oscar (Thor), Jerry (Odin) and me (Frigga). I just needed a Loki costume and Loki helmet for kids.

But there was no Loki. No. LOKI.


Everything about Loki comes back to the helmet. I googled Loki helmet, Loki costume, Loki pajamas and just about every other combination one can think of before I finally had to face the fact that I would be making this costume.

Our DIY Loki costume was as easy as buying a ninja costume online and adding some gold detail with Duck tape in just the right places. I did the same over the logo on a green cape we already had (Thanks @GoGoSqueeZ!).

You should see the Loki cosplay people have come up with. The costumes are so detailed and incredible. I watched a video of one guy who spent weeks crafting his Loki helmet and the results were awesome. I was overwhelmed but determined.

As I was figuring out my plans, I only took a couple of photos. I think they give a pretty good idea, so if you’re into DIY and want to give it a shot, here is how I made our Loki helmet.

I started with a foam safari hat from Michaels and cut off the brim. What’s left are a couple of curved pieces that worked perfectly for the sides of the helmet. I glued those to the hat with hot glue to make the sides and back of the Loki  helmet.

The thing that makes the whole costume are the classic Loki horns. This part was a lot of trial and error using poster board and masking tape to get the shape I wanted.

I cut out two curved pieces of poster board for each horn and taped them together on one side. Then I stuffed the horns with newspaper and taped the third side.

The end result was a 3 dimensional horn and I have to say I’m pretty happy with the results!

Finally, I created tabs with masking tape and cut small slits through the hat to attach the horns and I ran beads of hot glue all around the edges to secure them.

Once the Loki horns were attached, I added another strip of foam to the top of the helmet for some added detail and spray painted the whole thing gold. Just like that, our DIY Loki helmet was done!

Here is a side view. Really it’s about playing with the shapes and adding as much glue and tape as you need to get it right. Pretty technical right?

DIY Loki Helmet and Loki Costume in Action

I’m not gonna lie, y’all. I am thrilled with how the costume turned out. It was so fun to see people’s eyes light up when they saw the tiniest Loki ever.

Calvin loved his costume and even though I had planned to let him take it off if it got cumbersome, but aside from a few breaks he kept it on the entire night.

Loki really is the best villain and our DIY Loki helmet was a hit! We are huge fans of Disney Halloween Fun and costumes are just the beginning!

Getting hungry with all that costume design? How about some Mickey Mouse pumpkin cookies to go along with it?

UPDATE! There is now a LOKI halloween costume on Amazon! If you’re hoping to skip the DIY route, this may be just the thing you need.

I am so impressed! Your Loki helmet turned out amazingly well. I’m sure your little Loki loved wearing it around Disney World. We’ve done the Halloween event at Disneyland, but this one is still on my bucket list.
