Last Major Update:



From full mermaid dresses featuring a tail to mini skirts, shorts and leggings that look like they have fish scales, there are plenty of option for adult mermaid costumes around Halloween. You can use them to easily recreate an Ariel costume from the Little Mermaid, or you can create your own look and emerge from the sea in your own special sexy mermaid costume.

You will also need to decide what kind of top you want your outfit to have this October. Many women decide to go with a shell bra for their outfit, which is the most accurate depiction of mermaids from throughout history. At one time, this was proably the only real choice. However, there are now plenty of different top options right now. From blouses connected to your dress to halter tops, you can choose the right one to create the look of your own outfit.

For a great couples costume idea, pair it with a men's sailor costume or pirate costume. These two characters are the most likely to spend a large amount of time on the ocean and be in a position to possibly see a mermaid. Of course, attending a Halloween party with a large number of people greatly increases the odds that you see someone who wants to wear a women's mermaid costume for Halloween.
