Halloween is only a few days away and you’re running out of time to get your Halloween costume ready. If you’re looking for something easy and inexpensive to make, try this jellyfish costume! All you need is an umbrella, some streamers, and magnets. And, because you’re using magnets, you can reuse the umbrella after your Halloween party!


  • 1 Umbrella
  • White and blue streamers or tissue paper
  • Small neodymium magnets (2 per streamer)
  • Battery operated string lights (optional)


  1. First, prepare your streamers. The streamers are going to be the wavy tentacles of the jellyfish. For the tentacles, you can use streamers, strips of tissue paper or even ribbon. It depends on what you have available.
  2. Next, secure the tentacles to the brim of your umbrella using neodymium magnets. You can do this by using two magnets to secure each streamer. Just hold one magnet on the inside of the umbrella and then the other magnet on the outside to hold the streamer in place in between the magnets. To make it look like a jellyfish put the streamers along the edge of the umbrella so they hang down around you.
  3. If you’re feeling creative, you can add eyes to your umbrella jellyfish by using magnets to hold circles made out of paper in place. Or you can secure a string of battery operated lights to your umbrella to add glowing lights to your tentacles.

Depending on the color of your umbrella, you can add a layer of tissue paper to make it look more authentic or you can be an unusual jellyfish with a cool design. Again, this depends on what you have available to make your costume. A clear umbrella is ideal for this costume. So, if you have a clear umbrella and a string of lights, you can illuminate the whole jellyfish.

For this DIY costume, small neodymium disc or block magnets will work best. They have to be strong enough to hold everything together but small enough to not distract from the costume. You also need enough to hold your streamers and your lights in place so it depends on how many tentacles your jellyfish has. If you have 10 tentacles then you’ll need at least 20 neodymium magnets.
