Materials Needed

Before we begin, make sure you have the following materials:

  • Tulle fabric: Choose a color that resembles the vibrant hues of a jellyfish.
  • Wire: This will be used to create the frame for your costume.
  • LED lights: To add a touch of magic and make your costume truly stand out.
  • Safety pins: Ensure that your costume stays in place throughout the evening.
  • Ribbon: A nice finishing touch for added elegance.

With these materials at hand, you’re ready to dive into creating your jellyfish fancy dress costume.

Creating the Base

The first step in making your jellyfish fancy dress costume is to create the base. This will serve as the foundation for your costume and provide support for the tentacles.

Measurements and cutting

Begin by taking your measurements. Measure around your waist and add a few inches for comfort. Next, measure from your waist to your desired length for the tentacles. Once you have these measurements, it’s time to cut the wire.

Attaching the wire frame

Take the wire and shape it into a circle that fits comfortably around your waist. Secure the ends together to create a hoop. This will serve as the main frame of your costume. Make sure the hoop is secure and sturdy.

Creating the tentacles

Now it’s time to create the tentacles that will give your costume its jellyfish-like appearance. Cut long strips of tulle fabric, making sure they are longer than your desired length for the tentacles. Attach these strips to the hoop using safety pins, spacing them out evenly around the hoop. Continue attaching strips until you have enough tentacles to achieve the desired effect.

Adding Volume

To make your jellyfish fancy dress costume even more impressive, it’s time to add volume by layering tulle fabric and creating a ruffled effect.

Adding layers of tulle

Starting from the top of the hoop, begin attaching layers of tulle fabric in a spiral pattern. Each layer should be slightly shorter than the previous one, creating a cascading effect. Continue to attach layers until you reach the end of the hoop. This will give your costume a fuller and more voluminous appearance.

Creating a ruffled effect

To create a ruffled effect, use your fingers to gently gather and scrunch up the tulle fabric from the top down. This will give your costume the appearance of flowing tentacles floating underwater. Make sure to fluff out the tulle to achieve maximum volume.

Decorating the Costume

Now that you have the base of your jellyfish fancy dress costume complete, it’s time to add some decorative elements to make it truly spectacular.

Attaching LED lights

To add a magical touch to your costume, attach LED lights to the tentacles. You can use safety pins to secure the lights in place, making sure they are evenly spaced out. Choose LED lights that match the color scheme of your costume for a cohesive look. Once attached, turn on the lights and watch your costume come to life in a dazzling display.

Adding ribbons and embellishments

To give your costume an elegant finishing touch, attach ribbons and other embellishments to the tentacles. You can use safety pins or thread to secure them in place. Choose ribbons in complementary colors or sequins for some extra sparkle. Get creative and experiment with different textures and materials to make your costume truly unique.

Assembling the Costume

With the base completed and the costume beautifully decorated, it’s time to assemble the final pieces and make it wearable.

Connecting the tentacles to the base

Attach the tentacles to the wire hoop by securing them with safety pins or by tying them in knots. Make sure they are evenly spaced out and long enough to reach your desired length.

Making the costume wearable

To make the costume wearable, attach ribbons or elastic bands to the wire hoop. These will serve as straps that will hold the costume in place while allowing you to move comfortably. Adjust the straps to ensure a secure and comfortable fit.

Tips for Putting on the Costume

Putting on a jellyfish fancy dress costume can be a bit tricky, but with a few tips and tricks, it will become second nature.

Putting on the base

Start by putting on the wire hoop, making sure it rests securely on your waist. Adjust the straps to ensure a snug fit and comfortably distribute the weight of the costume.

Arranging the tentacles for a lifelike effect

Once you have the base on, take a moment to arrange the tentacles to achieve a lifelike effect. Fluff them out and arrange them in a way that they flow naturally around you. Don’t be afraid to experiment with different poses and movements to bring your jellyfish to life.

Safety Precautions

Safety should always be a top priority when wearing a costume. Here are a few precautions to keep in mind:

Securing the costume properly

Make sure all safety pins, ribbons, and straps are securely fastened before wearing the costume. Test the costume’s stability by moving around and stretching a bit to ensure everything stays in place.

Avoiding tripping hazards

Be mindful of the length and movement of the tentacles to avoid tripping or knocking over objects. Practice moving around in your costume before the party to get a feel for its size and shape.

Maintenance and Care

To ensure your jellyfish fancy dress costume lasts for many fancy dress parties to come, proper maintenance and care are essential.

Storing the costume

After the party, carefully remove the LED lights and other detachable elements. Store the costume in a cool, dry place to avoid damage from moisture or excess heat. Keep the tentacles fluffed up to maintain their volume.

Cleaning and repairs

If your costume becomes dirty, gently spot clean it with water and mild detergent. Avoid machine washing or vigorously scrubbing, as this may damage the fabric. If any repairs are needed, fix them promptly to prevent further damage.

Additional Ideas and Variations

If you’re feeling adventurous, here are a couple of ideas to make your jellyfish fancy dress costume even more unique:

Glow-in-the-dark effect

To make your costume truly mesmerizing, use glow-in-the-dark fabric paint or glow sticks to create a stunning glow-in-the-dark effect. This will make your tentacles come alive in the dark and add an extra element of enchantment to your costume.

Different color schemes

While the classic jellyfish colors are vibrant blues and purples, don’t be afraid to experiment with different color schemes. You can create a tropical jellyfish costume by using bright pinks, oranges, and yellows. Let your imagination run wild and create a jellyfish unlike any other.


Now that you have all the steps and tips in hand, it’s time to start creating your very own jellyfish fancy dress costume. With a little time and effort, you can transform yourself into a breathtaking underwater creature that will captivate everyone around you. So go ahead, enjoy the process, and have a fantastic time at your next fancy dress party.
