Mermaid Skeleton Costume

Mermaid Skeleton Costume How to Cosplay and Makeup

Hello, beautiful creatures! Today I’m sharing my mermaid skeleton costume with you, or as I like to call it, undead but delicious! I bought this costume a few years ago from Leg Avenue, and for some reason, I had it in two different sizes, so Dave and I wore versions of this on Halloween for our last Halloween party. I’m wearing an S/M, and he’s in an M/L.

How-to: Mermaid Skeleton Makeup

How-to Undead Mermaid Costume and Makeup

Below is how I created this makeup look step-by-step.


  1. I applied Urban Decay Sin Primer (a shimmery champagne beige) to my eye area.
  2. Smashbox Harley Quinn black cream shadow was applied to the lid and lower lid and blended into the crease like I was creating a single eyeshadow look.
  3. I lined the waterlines with Nabla Black Cupid’s Arrow.
  4. With a Sigma E25 brush, I patted Lethal Hit Point on top of Harley Quinn and blended out the edges.
  5. I used Lethal 8-Bit to blend out the edges of the blue Hit Point.
  6. With a flat brush to apply Concrete Minerals Glitter primer to the visible edges of my eye area above the crease and lower lid.
  7. The stunning Lethal Final Boss was blended on top of the Glitter primer.
  8. I smudged Lethal High Score at the lower lash line.
  9. I finished the look with Thrive Causemetics Liquid Lash Extensions Mascara, but I recommend using false lashes for more impact. My favorite are Velour Would I Lie? no-trim lashes.
  10. I used Nyx Lift & Snatch Brow Tint Pen in Gray Black to sketch in my tail, then beefed up the rest of my brows with Lime Crime Sleek Black Pomade Pencil.


  1. I applied Auric Glow Lust in Morganite 2.0 all over my face and blended it to my neck.
  2. About Face Shaken or Stirred liquid highlighter was applied with a stiff body brush all over my neck, decollete, shoulders, hands, and the tops of my feet. I wanted every visible piece of skin to glow.
  3. Danessa Myricks Yummy Skin Blurring Balm in Shade 1 applied by finger tips all over to blur and even out skin tone.
  4. By Mario Softsculpt Transforming Skin Enhancer in Light was applied with an angled blush brush to my cheeks, jawline, and hairline.
  5. Nyx So Taupe Sweet Cheeks Glow blush added a bit of definition to the hollows of my cheeks.
  6. Black Moon Jellyfish was used to highlight the tops of my cheekbones, the center of my forehead, and my clavicle bones.
  7. I used a flat brush to paint Danessa Myricks Pixie Dust onto my forehead, the tops of my cheekbones, neck, and clavicles. I wanted to create an iridescent mermaid-type skin effect without doing scales.


  1. KVD Poe pencil, a deep navy blue like Nyx Jet Set, to line and fill in my lips.
  2. Sugarpill Sub-Zero lipstick completed my look by applying it on top of the pencil.

Mermaid and Merman Skeleton Costumes

Dave used the arm pieces and headband to create his casual mermaid skeleton costume. Or should I say, merman?

The Last Halloween Party of 2022

Here are a few photos from our last Halloween party of 2022.

Final Thoughts

I wound down the evening holding Phobos, the sphynx cat, occasionally giving some sphynx spanks. This was a very comfortable mermaid skeleton costume, I might slightly modify the top before I wear it next time.

We had a wonderful Halloween this year! How did you celebrate? Did you dress up? The other costume I did this year was my Goddess Persephone Cosplay. I also wanted to do a Kuromi cosplay, but I needed more time to complete it.
