Who wouldn’t want to be a mermaid — not just for Halloween, but in life?! This costume can be done in its simplest form with makeup and a little beach wave, or decked out to the nines, depending on how much you want to put into it. The good news here is that this makeup tutorial can be the foundation for a simple sparkling tube dress or to a handmade fin skirt topped off with sand-covered pasties as your top…! Either way, you can totally transform into a mysterious sea creature in less than an hour!

1. Start with a natural makeup look for your base so you have a barrier of your normal makeup between the stage makeup just in case there are any sensitivities.

2. Apply a fuchsia shadow like Urban Decay Electric Palette in Jilted ($49) to your outer crease, extending slightly outside the corners to create a sort of a cat eye shading but thicker and on the outer half of your eyelid as well.

3. Add a dusty purple like the one from the Pop Beauty Sunshine Palette ($33).

4. Highlight the inside corners of your eyes and the lower lash line extending to the bottom of the cat eye with a vibrant blue shadow like Urban Decay Electric Palette in Gonzo ($49).

5. Dust on a light blue shadow like the one from Pop Beauty Sunshine Palette ($33) on your brow bone and inside corners of your lower lash line.

6. Add a peachy shimmery blush like Orgasm by Nars ($37).

7. Highlight your cheekbones with High Beam by Benefit ($17).
