Under the sea costume ideas are rarely used for occasions like Halloween and costume parties; however, the fact of the matter is that they are really great and should be considered! I’m not talking about wearing any of the under the sea costumes from Disney movies like The Little Mermaid and Finding Nemo; I’m talking about buying something unique or even creating your own homemade underwater costume!

There are literally hundreds of under the sea costumes that you can wear; however, I have chosen to describe 4 specific costumes that will suit the needs of many different people. In addition, these are highly recognizable, which is one of the qualities of good costumes!

You can dress up as an underwater creature for many different occasions. The most popular ones include: Halloween, a general costume party, an animal costume party, or even an employee costume event!

At the end of the day, it doesn’t matter which of these deep sea costume ideas that you choose to execute, as long as you do it properly!

Dress Up In A Fish Costume-Homemade Or Store Bought

Dressing up as a fish is definitely one of the most popular under the sea costume ideas for a few reasons:

-Fish costumes are easily recognizableAdult Clown Fish Costume-Orange And BlackCredit: Amazon.com

-There are a ton of fish costumes on Amazon being sold for really cheap prices

-A homemade fish costume can be created in as little as an hour!

There are obviously two options when it comes to dressing up as a fish for Halloween. You can choose to buy the costume from your local costume store/online retailer or create your own.

In regards to buying the costume, you should definitely take a look on Amazon, as they have fish costumes for up to 60% off of their original prices!

However, creating your own DIY underwater costume can be a bit more difficult!

1. The first step involves finding a long sleeve shirt and pair of pants that are the same colour. You should try to find a shirt/pair of pants that represent the colour of a certain type of fish. For instance, bright colours will usually end up forming a tropical fish costume!

2. Once you have found your clothing you need to make your own wide tail. Get a piece of felt and cut it into the shape of a fish tail that is about 12 inches wide by 20 inches long! Use some thread and a needle to sew it onto the back of your pants!

3. Next up are the gills. Take a large sheet of felt and cut it into two squares that are about 4 inches wide by 4 inches long! Sew the tops of each of those squares onto both sides of your shirt. A fish’s gills are always close to its head, so your should sew them towards the top of the shirt!

There are many ways to execute this homemade under the sea costume idea, but this is by far the easiest! You can literally make your own fish costume in less than an hour!
