Halloween only rolls around once a year, which means you'll need to dedicate some time to producing only the most shocking costume possible. Taking some ideas from the deep, dark blue sea is always a great way to gain inspiration.
Jellyfish are famous for their round, squishy bodies, which is why you can't nail the look without getting this step right. Luckily, it's easier than you might think, as you can purchase a clear blue bubble umbrella from practically any local retailer.
Now, you could keep the umbrella as it is and call it a day, but where's the fun in that? To spark things up a bit, use tape or Velcro to line the interior with purple fairy lights and make your jellyfish costume light up the night!
If your jellyfish needs a little personality, slap on a pair of eyes to the front of the umbrella using sturdy cardboard paper and glue.
Finally, the costume isn't complete without a proper set of tentacles. You can make these with anything from an old sheet to fancy gift-wrapping ribbon, but you'll need to make sure they're glued and taped securely to the inside of the umbrella.
Now swim on over to your next Halloween party, and get ready to shock everyone with your creativity!
