1. Begin by placing a fishnet pantyhose or a wig cap over your face.
You will look like the ugliest version of yourself during this step. It's worth it, I promise.
2. Start creating the mermaid scales
Using a sponge or your fingertips, tap a blue cream shadow like Maybelline Color Tattoo Cream Gel Shadow in Tenacious Teal at your temples, forehead and tops of your cheekbones.
3. Give the scales and ombre effect
Next, take a green cream shadow like Maybelline Color Tattoo Cream Gel Shadow in Edgy Emerald and apply below your blue areas, moving closer to the center of your face.
4. Highlight the scales with silver cream eye shadow
Using a silver cream shadow like Maybelline Color Tattoo Cream Gel Shadow in Silver Strike, tap on top of the high points of your face as highlights.
5. Remove the fishnets to reveal your makeup mermaid scales
Now, the fun part! Remove the fishnet and see the scales you've created!
6. Apply blue cream eye shadow
Using the same blue cream shadow and a synthetic brush or fingers, apply to the entire lid. Elongate the shape at the outer corners if you wish.
7. Make sure you blend the shadow
Using a synthetic crease brush, blend out the top edge.
8. Line under your lower lashes
Using a metallic teal eyeliner like Urban Decay's 24/7 Glide-On Pencil in Deep End, line your lower lash line and extend beyond the outer corner.
9. Line the rim of your lashes with a different shade
Use a mint green or aqua liner to line your waterline. Stila Smudge Stick Waterproof Eye Liner in Turquoise is my favorite!
10. Make sure you extend the line beyond your eye
Extend the line beyond the outer corner, below the teal line.
11. Seal your eye makeup with glitter adhesive
Dip your finger in glitter adhesive and loose blue glitter. Press onto the lid.
12. Add some glitter eyeliner for extra sparkle
Using a silver glitter liner, apply to top lash line.
13. Finish your mermaid eyes with mascara
Apply mascara to top and bottom lashes. I am liking L'Oreal Voluminous Miss Manga.
14. Add glitter to your brows, because why not?
For an extra touch, apply loose silver glitter to brows.
15. Apply false lashes (optional)
You can apply false lashes or simply some feather accents to the corners.
16. Start creating your mermaid lips
Line lips with the teal eyeliner, leaving the center open.
17. Give them an ombre effect
Take the mint green liner and fill in the center of the lips, creating an aqua ombre.
18. Yes, more glitter
Highlight your cupid's bow with the silver liquid liner.
19. Apply even more glitter
Press loose silver glitter onto the center of your bottom lip for extra dimension.
Now swim off and have a happy Halloween!
