How to Add Light to an Elsa Costume from Disney’s “Frozen”

Hello, it’s Sarah from! Today I want to show you a super easy way to add lights to your kids’ Halloween costumes. And what better way to do that than to follow one of this year’s hottest trends: Disney’s Frozen. Frozen is a very popular movie with kids these days, and my girls are no exception! This year, two of them will be dressing up as Frozen characters Elsa and Anna!

Adding light to Halloween costumes is a great way to make your kids stand out when they head out to Trick-or-Treat on October 31. It will give me peace of mind knowing my daughters are more visible with lighted costumes, while my girls will get a huge kick out of wearing lights and standing out among non-lighted costumes.

Here’s the video I did showing you how I added light to the Elsa costume. Below, I’ll give you a little more direction and show you the exact lights I used.


Alright. Here’s a quick rundown on the lights I used:

  • 3 strands of Cool White Fairy Moon Lights
  • 1 strand of Blue Fairy Moon Lights

Adding Light to Elsa's Hair

I used our cool white fairy lights, which come on a flexible, bendable silver wire. Fairy lights are tiny LED lights that are about the size of a grain of rice. By looping a 4.5 foot strand, I shortened it to about a one-foot length, or the length of my daughter's braid. Our fairy moon lights are the ideal fairy light due to its small, easily-to-hide battery pack.

Next, I braided the lights into Elsa’s hair, as pictured below. A simple braid works well. Just have your daughter hold the battery pack up top until the braid is complete as pictured below. The battery pack is about 2 inches by 3/4 of an inch by 1/4 of an inch, making it easily concealable. 

The final step is to tuck the battery pack into the top of the braid to secure it in place and hide it from view for the completed look:

Now we're ready to add lights to the cape!

Adding Light to Elsa's Cape

To light Elsa’s cape, I used three more strands of our fairy moon lights: two more cool white strands and a blue strand of fairy lights.

To attach each strand, I used clear packing tape:

I began by turning the lights on and applying the tape, then attached the tape to the clear fabric just inside the sheer white cape. Note that I did not loop these strands to shorten them like I did with the hair lights. Instead, I let them flow the full length of the cape. I do leave them slightly coiled for a more natural flow down the cape. This gives them added sparkle!

Do this two more times to complete the look.

This is a super easy and fun way to add lights to your daughter’s Frozen Elsa costume. If you are looking to add lights to your Halloween costume this year, check out our costume lights section.
