My daughter Ella loves all things “Under the Sea”, so this year she wanted to go as a Jellyfish! I figured it would be easy to make so we gave it a shot. I got the majority of the materials from the dollar store, because our goal was easy and cheap. And it turned out amazing! She smashed the costume contest and won first place, by a landslide!
For materials I used two dollar store loofahs, some small push dome lights (also from $ store), a kids clear dome umbrella (ordered this online for $10), giant googly eyes (found at target for $3), a pack of battery powered LED twinkle lights, and some rolls of tulle/ribbon I had. I went for anything iridescent and squiggly shaped! Oh and some long glow sticks! But it’s pretty open to interpretation and you can use whatever you have around the house to make the tentacles!
I wove some tulle and crinkly iridescent gift wrap in between the spokes of the umbrella to give the head some color, then I simply tied various lengths of tulle and ribbon to the spokes. Cut the string from the middle of the loofahs that holds it together and wah-la! Perfect jellyfish tentacles! so easy! I tied those on as well.
I tucked the dome lights up top and threaded the twinkle lights through some of the tentacles and taped the battery pack to the umbrella handle. I should have bought more lights but I was trying to stay cheap! And it worked out ok. everyone absolutely adored her costume and it looked so pretty both during the day and when it was all lit up at night!
The only part I would change is that she had to hold the umbrella and her candy bag all night while trick or treating, so if I had to do it again I would rig up some sort of way to attach it to her and not make her carry it, but she loved it and wanted to show it off to everyone and everyone wanted to stop and take her picture!
Sexy Jammin’ Jellyfish Couple Costume
It seemed a little ambitious at first to create LED-lit 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 two felt cowboy hats and two 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). Since 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 sequinned 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! These were a total blast to make and wear, and like I said everyone adored them. If you’d like more detail about what I used or did to make my Jellyfish costume, please let me know.
Cute Jellyfish Costume
My three year old daughter Mazie was very specific and unwavering in what she wanted our costumes to be this year: jellyfish for her, octopus for baby brother Julian, sting ray for mom and shark for daddy. No one can establish their opinion quite as firmly as a three year old. Perhaps we’ve been spending too much time at the National Aquarium.
Being the queen of time management, I wisely decided to start costume construction three days before Halloween. My evenings and nap times were consumed by chiffon, lamé, and only the occasional curse word.
Mazie’s Jellyfish costume required the most effort and time. I covered my straw hat with fabric, stuffed it with batting and then hot glued all the fabric and ribbon tentacles. My burnt and raw fingertips were glad that the rest of the costumes only required sewing, including her jelly fish pants and arm bands. Her pattern for the pants were made simply by tracing a pair of leggings she already owns. We had quite a few talks about how fun it is to wear (and keep on) a jellyfish hat, so luckily the hat stayed on through two parties and one vigorous round of trick or treating.
We won our church costume contest. Neighbors were genuinely surprised to see homemade costumes. A specific neighbor was so thrilled that she offered to give us all the costumes that she made for her now grown daughters.
Everyone loved the costumes, especially my daughter who didn’t even trip on the tentacles once. The tentacles did have the habit of scooping up fallen leaves when we were jumping in leaf piles. My mom loved the jellyfish costume too and she raised me in the truth that Halloween is the most important holiday of the year, and homemade costumes are the best way to show your family you care.
Scuba Diver Trapped by a Jellyfish Costume
This year my son 7 year old son Aiden wanted to a Jellyfish costume. His class is currently studying sea creatures and he loves reading about jellyfish & starfish.
First, I used a clear bubble umbrella for the frame of the jelly. I covered the frame with rolled up bubble wrap, spiraled from top to bottom. Next, I covered the bubble wrap with a blue iridescent blue fabric. This part was a little tricky, I pinned the fabric with safety pins first, then when I got the placement of the fabric complete I used a glue gun to secure the fabric to the umbrella.
Before gluing the fabric, I secured blue lights inside the upper part of the umbrella and attached the battery pack with the on/off switch to the upper base of the umbrella with a zip tie. Also attached were 3 EL wires, secured to the top of the umbrella hanging down to blend in with the fabric tentacles.
The tentacles were made from strips of fabric with a stitch down the middle to add curl. The remainder of the tentacles were made from deconstructed loofahs. Glow in the dark fabric dots were added to some tentacles and the rim of the jellyfish.
People really enjoyed this Jellyfish costume, especially at night when it was all lit up. The challenge was that the costume was a little on the heavy side so we helped him carrying it when needed. The scuba diver part of the costume was made from two water bottles painted silver with reflective and electrical tape, electrical cord tubing was attached to the top of the water bottles with a piece of pipe insulation for the mouth piece complete with a pacifier for the mouth piece.
The belt was made from a nylon strap with clip together attachments, weights were made from a scouring towel from the dollar store, and a light up jellyfish was attached to the belt in a mesh bag.
Final touch, fins made from foam & duct tape, and a scuba mask. Aiden loved wearing this Jellyfish costume & wears all the scuba stuff around the house still. This costume won a prize in the most creative costume category.
Bio-Luminescent Jellyfish Costume
I made this Jellyfish costume for my five year old niece as part of the underwater theme that her and her brother chose this year. I originally planned to take a clear umbrella, toss on some battery operated lights and glue some ribbon on. However, I decided to take it a few steps further.
After seeing how boring the plain umbrella looked, I ran out to JoAnns and purchased (after one hour of scouring and debating) a shimmering fabric that would look like a jellyfish while meeting the desires of a five year old who is obsessed with pink and purple.
I carefully glued the fabric to the umbrella with a hot glue gun. While this was convenient (or so I thought it would be), it was was probably not the best adhesive as it melted through the umbrella and landed on my hands many times.
After gluing on the fabric, I added pink “fairy lights” to the inside of the umbrella by wrapping the lights around the metal support of the umbrella. In order to make the tentacles of the jellyfish glow, I purchased EL wire from Amazon (it came assembled with 6 wires and one battery back.
I decided to add foam board (purchased from the dollar store – the kind that is used for presentations) and cut it to fit the bottom of the umbrella. After gluing the foam board onto the umbrella, I made little holes in the board and brought the EL wire through the holes. After all of the lights were added, I glued wired ribbon (this was the most expensive part of the costume) around the umbrella. Prices of materials used: Clear umbrella – Amazon ($6), Fabric – JoAnns – ($12 with coupon), fairy lights – Amazon ($6); EL wire – Amazon ($12), Ribbon – AC Moore ($18), Foam board – Dollar store($1). Total price $55.
The one thing that I did not really think about while I was doing this costume was how was a five year old going to carry this for over an hour while attempting to trick-or-treat. The day of Halloween, I decided to use one of her old backpacks and ziptied the handle of the umbrella to the backpack and then she just wore the backpack.
On Halloween night, her costume received a ton of compliments. There were people stopping her at every house. We even had several people take pictures of her costume. She felt like a rock star!
Glowing Jellyfish Costume
My 8 year old daughter wanted a glowing Jellyfish costume for Halloween. OK. Here’s how we pulled it together.
Glowing Jellyfish Costume Instructions
- We took an old sombrero and spray painted it blue.
- Then we filled it with a long coil of bubble wrap.
- Next, we added silver party bag filler for sparkle.
- Then we hot glued green battery operated lights inside.
- We covered it with a layer of bubble wrap, flat side up, to make it smooth.
- The whole thing got a wrap of sheer, yet shimmery fabric.
- Then we hot glued sparkly ribbons, elastic sparkly ribbon, and fabric spirals in iridescent fabric around the bottom.
- The costume was awesome, but it needed more, so I added a skirt onto a black t-shirt.
I then made a caplet to hold more fabric tentacles.
This costume is beyond cool. It floats when my daughter walks. I am so excited for Halloween and she is over the Moon!
Stingingly Smart Jellyfish Costume
I came up with this amazing Jellyfish costume idea by searching Google. Typed in “inexpensive, creative Halloween Costumes” and found a few photos of the jellyfish idea. I am an elementary grade level science teacher and began to research different species of jellyfish. I am currently teaching bioluminescent creatures, and decided to design the costume based on this characteristic.
I used a clear umbrella, EL wire lights, battery operated LED lights, bubble wrap, purple, pink and white transparent ribbon, cloth, wired, and Grosgrain, an old satin table cloth, Christmas tree tinsel, satin cloth and iridescent material, duct tape, fabric glue, staples and zip ties to secure many items.
Curled the ribbon, cut the bubble wrap into long skinny lengths, and began securing them inside and on the rime of the umbrella. Many of the items I had at home. Bought white pants and a white shirt, used a scarf for around my neck to represent a tentacle, and wore a bright pink wig to enhance my color scheme, just in case someone wanted to see who or what was inside the umbrella.
The reactions were many! Most knew it was a jellyfish, even a seven year old boy having dinner with his family. All loved the idea, had at least 20 pictures taken, some with people that wanted to be in it with me, but most took a pic of the jellyfish alone.
Everyone wanted to know how I made it, how long it took me (40-50 hours) and where I got my inspiration. Those that know me, were not surprised that it was a jellyfish, I have been teaching in this county for 24 years, 23 of those have been in the curriculum of science!
I won the costume contest; came in first for most original. There were about 75 entered.
This was by far the most intricate, time consuming costume I had ever created. It was also the most fun I have ever had at a Halloween party.
Each year, our school: Forest Ridge Elementary, has a staff play that we put on for the students. We dress up, have a narrator read the play while we act out the parts, stop the narration several times and play age appropriate, present time music and go out into the audience and dance with the students.
Narration begins again and we go back on stage, narration stops, go dance, etc. This year we are doing our own rendition of Frozen, and have the story come to Florida, jellyfish costume will be used for this too! I can’ trait to see the students reactions to this incredible creation I have made, they will love it! After all, it is about the students enjoying the play! I plan on entering in another contest this coming weekend.
Stingingly Smart Jellyfish Costume
My daughter loves fish. We decided we could make her a great jellyfish costume. I found a clear umbrella from Target that cost was $20 but we have used it after the fact as its intended use.
I bought iridescent plastic streamers (not paper in case of rain!) that were adoor entry decoration and cut them down to a length that went from the inside of the umbrella to about her knee length. This was taped with clear packing tape to the inside of the umbrella and some pieces were tied to the spokes of the umbrella.
We dressed her in violet like the main color of the streamers. The dilemma was how could she trick or treat carrying an umbrella my husband thought of using a backpack we stuffed a pillow in it and then used a backpack with dual zipper that closed at the top and center of the backpack opening which allowed the umbrella post to sit balanced above her head. We covered the backpack with an iridescent tablecloth from the dollar store. I cut the tablecloth with streamer like edges and she wore it like a cap. Both her hands were free to hold a back for trick or treating and she was protected in case it rained while she was out getting candy! It was also light weight.
A little time is needed to get the right pillow to backpack ratio and we ended up typing the backpack closed with string as the zippers were pressured by walking movement. When she wanted to take a break she just took the backpack off.
Total Spent: $28
