Halloween means scary movies, trick-or-treating, and, of course, dressing up like a creepy creature or your favorite character. When it comes to the costume tradition, your options are endless. You can be whatever you can buy online, find at the thrift store, or DIY yourself, including the super cool and multi-colored mermaid of your childhood dreams.

From the spooky, siren-like mermaid to the classic, red-headed Ariel, there are many looks to choose from within this costume choice (per Country Living). Even if you’re simply wearing a faux tail that you bought online, you can really bring the outfit to life in whatever way you want with the help of eyeshadow, glitter, and highlighter. In this way, makeup is one of the mermaid costume’s most creative and customizable elements.

Lucky for you, there are some simplified mermaid makeup tutorials out there, so you can choose whatever suits your Halloween vision best.
