This homemade costume for women entered our 2014 Halloween Costume Contest.

A word from Desiree, the 'LED Jellyfish' costume creator:

It seemed a little ambitious at first to create LED jellyfish costumes that would be believable and funny, yet cute. But I am so pleased with how they turned out and we really were the hit of the party (many parties) on Halloween. Here’s how I made them:

I started by purchasing 2 felt cowboy hats and 2 salad bowls from the dollar store – these were used to make the tops by hot-gluing the salad bowls upside down onto the felt hats. I then wrapped many layers of blue glitter tulle around the tops, until you could no longer see the hat or bowl underneath.

Next, I used the battery-operated LED wires I had ordered from Amazon – they were about $5.00 each and SO beautiful and bright (plus, they still have juice from over 24+ hours of being on). Because I intend to reuse them, I placed a Velcro strip on the back of the battery pack with a corresponding strip on the inside of the hat – this way I could attach the lights to the top but they are removable. I wrapped one strand of wire around the tulle (taping every so often to keep it in place), and then I went over the wire with a few more layers of tulle to hide the cord.

For the tentacles, I went to the craft store and bought a variety of jelly-esque fabric/material – like sequined ribbon. I scrunched some of the blue glitter tulle and wrapped it around the base of the top, so that I could tie each ribbon in little knots from the tulle. I cut them at varying lengths so they looked realistic.

And that’s basically it! To make two, it cost me around $50. These were a total blast to make and wear, and like I said EVERYONE ADORED THEM.

How many led strips did you use on one hat?

#2 comment by olive October 26, 2015

Did you use 2 felt hats and 2 salad bowls per costume or was this the total supply to make both of your hats in the picture?

I love this idea and am happy to see someone else made it happen with success! Any other tips you have for me would be amazing.

Hi Olive,

The 2 felt hats/salad bowls are the total supplies - sorry if that's confusing! If you have any more questions feel free to ask! Super excited for someone else to try it out :)

Thank you so much!
