Mermaid Makeup Tutorial
Enhance your experience as a mermaid and elevate your costume by following our mermaid makeup tutorial that’s perfect for beginners. Grab your favorite teal eyeshadow and glide it on each lid to accentuate your aquamarine-colored tail. Offset the bright teal shadow by adding magenta eyeliner to the upper and bottom lash line. This pastel color palette is rounded out by an application of light pink blush to the apples of both cheeks. Next, take matching lipstick and swipe it across the lips. Finally, take a pair of fishnet stockings, stretch them over the sides of the face, and use shimmering teal shadow to blot scallop shapes on the skin. It’s a simple makeup technique to create a beautiful fish scale effect.
