If you’ve dreamed of being a mermaid, you’ve probably tried the hack where you place a pair of fishnet tights over your face and go over top of it with eyeshadow to create a scaly look. While it has an awesome finish, it’s definitely not the only mermaid look. FYI: Neither is Ariel’s red hair and natural makeup. There are as many mermaid looks as there are, erm, fish in the sea. And that’s why mermaids are a brilliant option for Halloween.
