What costumes are you making this year?! I had fun crafting this glow in the dark/ light up diy jellyfish costume that my daughter can’t stop dancing in! I knew she wouldn’t go for anything on her head but a fluffy tutu and a leotard make this easy to wear and quick to make. It’s easy to make in a night and I have a full tutorial to make it even easier for you!
This post was sponsored by JOANN, which means they supplied materials and compensated me for my time, but all opinions are my own.
My kids and I had such a fun time picking out all these trims, there’s just something special about browsing things you can touch instead of online shopping.

I like the more anatomically correct costumes with a big bowl or boning on their heads but I knew she’d never wear it! This is perfect because it’s fun to run around “flying” in and easy to take on and off for car trips and bathroom breaks.
Didn’t those tendrils turn out cute! I had so much fun making this.
We usually do Halloween stuff during the day so I thought I’d include a light up option that made it feel special as well!
Of course the main selling point is that the tulle glows in the dark (!). There is a touch of glitter, too, so naturally it’s her new favorite fabric. The LED lights seemed to “charge” the glow in the dark functionality too, making it functional and pretty!

Diy jellyfish costume
- 5 yards of purple glow in the dark tulle
- LED purple light strip
- 1 yard 1″ purple elastic (or 2″ and sew it narrower, as I show)
- Rotary cutter
- Acrylic quilt ruler
- Purple leotard
- 1 package wired purple ribbon
- 4 yards Chiffon flower trim
- 1 package Ruffled purple ribbon
- Hand sewing needle
- Lighter (optional)
Step 1- Cut your elastic! My daughter’s waist was 22″, I cut 19″ of elastic and sewed it with a 1/2″ overlap. I couldn’t find thinner purple elastic, so I then sewed it in half again, making it 1″ wide. Step 2- Cut tulle strips! I cut my strips 36″ long and 5″ wide. Tie each one on the elastic with an overhand knot, and repeat until all 5 yards worth of strips are on!
Step 3- Cut your trims! I cut them to roughly 26″ long a piece, using up the material as outlined in the supply list. I also used a lighter to seal the edges of the ruffled ribbon, or fray check would work as well. Hand sew them spaced roughly around the skirt & two on the arm seams of the leotard.
Step 4- Hand sew the LED light battery back at the back of the skirt and then loosely loop the fiber through the skirt, adding a stitch here or there to secure. I let the battery box just gently hang from the waistband, it didn’t bother her!
Let me know if you’ve experimented with glow in the dark or light up elements?
