Mermaid Fashion

Mermaid inspired fashion is here for Summer of 2023, and I am here for it! Lizzo recently caused a stir with a beautiful mermaidcore manicure featuring green and silver crystals, Dua Lipa is looking fabulous as a blue haired mermaid in the Barbie movie, and Halle Bailey is stunning as Ariel in the new live action The Little Mermaid. However, mermaids have featured a lot in my own work too!

Mermaids in my life

Hollowhood, JJ Barnes, Siren Stories

In Hollowhood, (written and directed by me and my ex partner Jonathan McKinney, my character Bethany Palmer wears a mermaid necklace, that she then lends to Penny. When Penny wears it, it is noticed by her ex-girlfriend Olivia during a tender scene as they estranged couple reconnect after a night of drinking and dancing… before things start to get super spooky. Penny is even wearing it in the poster for the film! Hollowhood is streaming now on Plex and Tubi, and hopefully coming to more platforms soon so do check it out.

My second book, Lilly Prospero And The Mermaids Curse, (obviously) features mermaids heavily throughout. The mermaids are being hunted by a Harvester, who pulls them from the ocean to sell their body parts on the magical black market, keeping them alive for as long as possible as he chops them up slowly (grim). My heroic teenage team, Lilly and Saffron, want to find and stop the man responsible, but things get complicated and soon it’s not just the mermaids who are being hunted, but Lilly and Saffron themselves.

This love of mermaids has been present throughout my life, and so this new mermaid fashion trend is very exciting for me! So, I decided to share some of my ideas for how we can enjoy and embrace this fantastic fashion trend!

Mermaid Manicures

A mermaid manicure typically features shades of blue, green, and pink, and often includes seashells, fish scales, and other aquatic motifs. Mermaid manicures can be done with gel polish, regular polish, or acrylics. While you can get them done professionally at a salon to achieve a Lizzo standard, you can also have a play at home!


Rimmel 60 Seconds Super-Shine, 8ml, Mermaid Fin

I completely LOVE this gorgeous nail varnish. The shimmering colours definitely evoke the feeling of mermaid fashion, and it’s a nail polish that dries in 60 seconds and provides high-impact color with an ultra-shiny finish. It is a one-step nail polish that does not require a base coat or top coat. It is also free of formaldehyde, toluene, and DBP.

Here are some tips for using Rimmel 60 Seconds Super-Shine, 8ml, Mermaid Fin:

  • Apply one coat of polish to each nail.
  • Let the polish dry completely before applying a second coat.
  • For a longer-lasting manicure, apply a top coat.
  • Enjoy your beautiful, shiny nails!

Mermaid Hair

In the upcoming Barbie movie, we’re all super excited to see Dua Lipa’s blue haired mermaid Barbie, and pinterest is full of gorgeous mermaid hair trends. When you get your hair done professionally, a mermaid hair style will feature loads of beautiful blues and purples, layred through you hair, and it looks AMAZING.


However, these are some tips for styling your hair in mermaid style at home:

  1. Start by washing your hair and conditioning it.
  2. Apply a leave-in conditioner to help protect your hair from heat damage.
  3. Use a curling iron or straightener to create waves or curls in your hair.
  4. Once your hair is styled, divide it into two sections.
  5. Secure one section of hair with a hair clip.
  6. Braid the other section of hair.
  7. Once the braid is complete, secure it with a hair elastic.
  8. Repeat steps 5-7 with the other section of hair.
  9. Once both sections of hair are braided, twist them together and secure them with a hair elastic.
  10. Use the qiqiqiaqia Pearl Starfish Rhinestones Hair Clips to secure the braid in place.
  11. Add some seashells, fish scales, or other aquatic motifs to your hairstyle for a more mermaid-like look.

Mermaid Make Up


Mermaid make up is all about having fun with bright colours and shimmering glitters. Don’t go for classy and understated! My best recommmendation is the Makeup RevolutionLondon 32 Eyeshadow MERMAIDS FOREVER because of the number of fabulous colours you can pay with.

How to do mermaid makeup:

    1. Start by applying a primer to your eyelids. This will help to create a smooth base for your eyeshadow and prevent it from creasing.
    2. Use a light-colored eyeshadow to create a base for your look. You can use any color that you like, but a light blue or green would be a good choice.
    3. Apply a darker blue or green eyeshadow to the crease of your eyelids. This will help to create depth and dimension to your look.
    4. Use a shimmery blue or green eyeshadow to highlight the lid of your eye. This will help to make your eyes look brighter and more awake.
    5. Use a black or brown eyeliner to line your eyes. You can use a liquid or pencil eyeliner, whichever you prefer.
    6. Apply mascara to your eyelashes. This will help to make your eyelashes look longer and thicker.
    7. Use a highlighter to highlight your cheekbones, brow bone, and Cupid’s bow. This will help to add a touch of glamour to your look.
    8. Use a lip gloss or lipstick in a light blue or green color. This will help to complete your mermaid look.
