1- Jellyfish Costumes That Light Up
Jellyfish Costume from a hat by Press Print Party!
Skip the umbrella—this light-up jellyfish costume uses a big hat topped with a clear punch bowl, wrapped in blue tablecloths with wavy plastic-strip tentacles.
Tuck battery-powered fairy lights between the hat and bowl for that dreamy glow, and you’ve got a hands-free, budget-friendly costume you can pull together fast. Total crowd-pleaser on Halloween night!
Jellyfish Umbrella Costume
Grab a clear dome umbrella and tape long strips of iridescent cellophane, ribbon, or plastic tablecloth around the inner rim for swishy tentacles.
Spiral a battery LED fairy-light string along the ribs under the canopy and Velcro the battery pack near the handle so you can flip it on and off.
Add a little tulle or cellophane inside to diffuse the glow, and keep the front clear so kids can see. Dress in black or sea tones, pop the umbrella open, and float down the block like a bioluminescent showstopper.
2- Storm Cloud Halloween Costume That Lights Up
A clear umbrella, fluffy batting, and LED fairy lights = instant thunderhead. Glue batting on top and underneath the canopy, then tuck lights between the layers so the whole cloud glows from within.
Dangle fishing line strung with acrylic beads around the rim for raindrops—or weave in a second strand of fairy lights if you want “lightning” showers.
Or use balloons like in this cloud costume tutorial from Tikkido for a quick costume that is sure to turn heads.
Forecast: 100% chance of compliments.
3- Tornado Costume with lightning
Spin up a storm with this easy build: wrap gray tulle around a trimmed tomato cage (Martha Stewart’s clever base), then weave in a couple strings of battery-powered fairy lights so your mini twister glows as it swirls.
Kids will twirl and twirl all night—so maybe pace the fun-size candy bars unless you want them to spin ’til they lose their cookies.
4- Light-Up Skeleton Costumes
Want bones that really pop after dark? You’ve got options—glow paint, glow sticks, or go full neon with EL wire. And yes, you can totally just buy one, too.
Glow-in-the-Dark Paint Skeleton by Armelle Blog
Classic and comfy. Paint simple bone shapes on a black tee and leggings with glow-in-the-dark fabric paint, let it cure, and you’ve got a rechargeable glow (just “charge” under a bright light before heading out).
No wires, no bulk—perfect for classroom parties and easy trick-or-treating.
Glow-Stick Skeleton by Hello Wonderful
Fast, bright, and very “whoa.” Attach glow sticks to a black outfit to outline the bones—instant shine with zero crafting stress.
Tip: bring extra sticks for a mid-evening refresh and secure them with clear tape so they stay put through all the candy-fueled wiggles.
EL Wire Skeleton
Want the coolest effect? Try EL wire for a crisp, neon outline you can see from down the block.
Attach it to a black hoodie and pants, tuck the small battery pack in a pocket, and you’ve got a walking light show.
The trick with EL wire is to use some black electrical tape on the portion you don’t want to show.

Not a DIY night? No problem. There are plenty of options to get one delivered quick.
5-LED Stick Figure Costume
The odds are, when you think of a Halloween costume that lights up, a stick figure pops to mind first.
It’s the internet’s classic ‘living doodle’—instantly recognizable, ridiculously fun, and an instant crowd-pleaser.
Start with a black hoodie and pants, then outline the torso, arms, and legs with glow sticks (quick and cheap) or EL wire (brighter, cleaner lines you can reuse).
Tape or Velcro circles at the joints, pop a ring on the hood for the head, and tuck any battery pack in a pocket.
The best part? Put a whole group in these and from afar it looks like a bunch of animated stick people busting moves—perfect for goofy dance videos and guaranteed giggles.
Not in a DIY mood? You can buy a ready-made light-up stick figure suit and call it a night.
6- Abducted by Aliens Costumes with Lights
Become the headline of a small-town newspaper with this hilarious illusion.
DIY Alien Abduction Costume DIY by Mother of Grom
Build a UFO “saucer” that hovers above your head and beams you up in lights.
Cut a big cardboard circle, add a clear bowl dome in the center, wrap the rim in foil, and line the underside with battery fairy lights.
Hang tinsel or acrylic-bead “tractor beams” so it looks like you’re mid-abduction.
Mount the saucer to a backpack frame (PVC works) so it floats over you while you walk—zero arm strain, maximum giggles.
Fast-track DIY Alien Abduction costume by Fun365
Oriental Trading’s Fun365 has a kid-friendly version you can adapt—just weave in lights for the glow.
Glow upgrade: Outline the saucer rim with EL wire for a crisp neon UFO vibe; battery packs tuck into the backpack pocket.
Two-Umbrella UFO (so clever!) by Costume Works
Flip one clear umbrella upside down for the saucer bottom, nest a second right-side-up on top, and zip-tie the frames together for that classic disc shape.
Wrap LED strip or fairy lights around the rim, hide battery packs under the canopies, then hang an iridescent tinsel curtain between them as the shimmering “tractor beam.”
Lightweight, rain-ready, and hilariously photogenic—ET would 10/10 approve
More DIY Alien Abduction Costumes
This first one from Costume Works is made with foam board and a plastic bowl and includes some instructions.
The next one is just fun.
7- Glowing Angler Fish Costume
Another under-the-sea costume that lights up—and it’s jaw-dropping.
It’s definitely a labor of love, but the payoff is spectacular.
I couldn’t find a step-by-step tutorial anywhere, just inspiration photos (some cardboard builds, others fabric and foam).
Not up for the marathon DIY? Grab a ready-made light-up angler fish costume and call it a catch.
8- Genie Costume With a Cloud of Smoke
Grant three wishes and a photo op. Line a black skirt with LED fairy lights and fluff Halloween spider webbing for that dreamy “smoke from the lamp” effect (brilliant inspo from Costume Works).
Add a vest, headpiece, a little blue makeup if you’re feeling extra, and a toy lamp on your shoe—boom, instant genie with built-in sparkle.
9- Snail Costume with a Glowing Trail
Slow and glorious.
Make the shell by tightly rolling packing kraft paper into a spiral, hot-gluing as you go, then mount it to a cardboard oval and wear it with backpack straps.
Dress your little snail in brown or mossy green, add a headband with pom-pom eye stalks, and finish with a “slime trail”: a long strip of tulle with a string of battery fairy lights tucked inside.
Pin or Velcro one end under the shell so it drapes and shimmers behind them, a glowing, magical snail tail trail.
Mom hacks: Keep the trail detachable (Velcro/snaps) for stairs, or trim to ankle length to avoid trips.
10- Glowing Fairy Wings
A absolute classic with a big impact.
Store-bought wings are cute but tiny—if you want the big, jaw-dropping glow, these two tutorials are the move.
Both use sturdy poster board (and lots of patience) to create massive, light-lined wings that look straight out of a fairy tale.
Totally worth it when your little fairy floats by all day long like a life-size firefly.
These adorable fairy wings were for a Tinkerbell costume and come with video instructions.
And these large pink fairy wings use fabric to diffuse the glow and come with a very thorough tutorial with lots of pictures.
