The mystical creatures that live in the ocean will forever win over our Halloween hearts. Especially jellyfish! Their various hues and transparencies make costume designing so intriguing. I have to admit, my inspiration for this tutorial for how to make a jellyfish costume also came from the fact that autocorrect always changes “Kelly” to “Jelly.” So of course it was obvious I had to create a tutorial detailing a few ways to make a jelly(fish) costume. I’ve got three different ways to show you, so grab your besties and get ready to spend a night under the sea!


Materials + Tools:

– various sheer/metallic fabrics

– silver spray paint

– LED battery-operated lights (buy them here)

– skirt hoop (buy it here)

– head umbrella

– scissors

– hot glue


Umbrella Hat Jellyfish

So what is the true use of the umbrella hat?


The rainbow umbrella hat is quite the statement, but for this mystical jelly you will want to spray paint it all sliver.


Cut out a bunch of one-inch strips from various sheer, shiny fabrics. The more various the textures, the better.


Use a hot glue gun to attach the strips around the top of the umbrella hat. Pro tip: Attach more strips in the back than the front so you will be able to see where you’re going.


Place your jellyfish hat on your head and have a friend help trim the tentacles to your desired length. Pair your hat with a shiny, mystical dress. We love how this one has an asymmetrical hemline. Don’t forget to decorate the waist and headband with extra jellyfish strips.


We added the battery pack lights to the top of the headpiece and draped them down the front. What’s great about this pair of lights from Amazon is that they come with a remote and have different settings. The flashing string of lights will really help create a statement on the dance floor. But of course, you should also do lots of spin moves and watch those tentacles twirl!


This is the easiest watercolor paint effect you can get. All you need to do is heavily highlight your face with a bright illuminating highlighter and then stipple (lightly tap repeatedly) brightly pigmented shadows in hues of purple and blue. Line your eyes and deepen your creases with purple and/or blue. Misty used the same technique for all three gals.

Hoop Skirt Jellyfish


Remember that hoop skirt from the flamingo costume? Well, we are using it again. This time, cut the skirt so only two layers remain.


Spray the inside and outside with silver spray paint. *Yes, it does look like something Zeon from the 21st century would wear*


Attach more strips of fabric to the waistband of the skirt. Make this really dense by overlapping three strands and hot gluing them together.


Have a friend help trim your tentacles to the perfect length. Tripping on them would be a huge #partyfail.


We draped the LED lights throughout the skirt and tucked the battery pack in the waistband. Of course, when wearing a skirt with a ton of tentacles, you must shake it. There is nothing else you need to do.


Umbrella Jellyfish


Krystle was actually a jellyfish last year for halloween and brought her costume to share in the jellyfish fun. Her costume is created out of a bubble umbrella and various sheer and shiny white fabrics. She wrapped the umbrella in the fabric, gathered it on the underside and secured with safety pins.


This is also where she attached various cascading pieces of fringe, ribbon and tinsel.


Krystle suggests pairing your umbrella jellyfish with anything lacy, especially lace bell-bottom pants!


Gather up your gals and head to school — a school of jellyfish, that is.
