DIY Little Mermaid Costume | Black Ariel Inspiration

by Kaya Marriott

Although this costume inspiration is for absolutely anyone, as a Black woman, I was inspired to do this Halloween costume because of Halle Bailey’s upcoming 2023 portrayal of Ariel in Disney’s live action The Little Mermaid.

I made my costume *mostly* from scratch, over the course of two days. Which was incredibly ambitious, but the frantic countdown of working on a costume days before Halloween has become my own chaotic tradition.

I’ve always wanted to try my hand at cosplay, so this is my one time a year where I get to pretend I’m anything close.

And I’d like to note there is something incredibly satisfying about getting a compliment on a Halloween Costume, and getting to respond with “thanks, I made it!”.

Becoming the Little Mermaid for Halloween

So now let’s get into how I brought my costume to life, sharing in the order that I worked in…

Which in hindsight, is again.. a little chaotic.

Ariel’s Red Hair

If you want to do the simple thing, I recommend you buy a red wig.

But I have a personal goal of recreating beloved cartoon and anime characters with a “Black Girl Magic” spin. This usually looks like seeing how I can represent their hairstyles using my natural hair or a protective style.

So when it came to becoming Ariel, I knew I wanted long, vibrant red box braids. And I think faux locs or twists would also be gorgeous.

But considering I was working on a very tight time limit, I wasn’t able to get the colour I wanted.

I originally wanted something like either of the below.

But I ended up only being able to find Ombre Black to Burgundy/Red braiding hair. Which is a colour I’ve actually done a few times before.. and I knew wouldn’t fit my vision.

Black Blogger partially finished braiding hair in box braids, unimpressed selfie.
Honestly, one row in and I was ready to give up on the whole project.

I decided to persevere, and about… 16 hours later I finally finished.

And then I ended up buying some red temporary hair spray from the costume store. I was also considering some red hair wax, but couldn’t find any on such short notice.

Vancouver is really lacking in beauty supply stores…

Finished result -- Red Ombre Box braids sprayed with red hair color dye.
It’s a bit hard to tell in this light, but this is after spraying my hair with temporary colour.

The Little Mermaid Tail

Level Easy: buy an actual tail or just wear a cute green skirt.

If you opt to just purchase your Little Mermaid Tail, below are some great options I was eyeing on Amazon. (I couldn’t order any of them in time, which is partly why I was forced to make my own bottom.)

Level Kaya: hand-sew a skirt from scratch even though you suck at arts and crafts.

If you’re opting to mostly make your costume, like I did… you will need a stretchy and shiny fabric for the main part.

I bought mine at Dressew in Vancouver, but I’m sure you could order online, or find something similar at your local craft/fabric store.

Then I cut and sewed by following a video I found on YouTube for a DIY Pencil Skirt.

Then for the bottom–the fin portion, you’ll need something puffy/fluffy/flowy. I originally was going to purchase organza and tulle.

But then I went to Spirit Halloween and found a green tutu. I promise you.. it works beautifully, just wait.

I was feeling lazy and just fabric taped it to the bottom of the skirt I made. I probably should have sewed it though, because it kept coming undone…

Ariel’s Purple Shell Bra

Level Easy: Buy a purple top, bandeau, or shell-like costume.

Level Kaya: Buy purple organza and hand stitch it to an existing purple bandeau swim top.

It was cute… but extremely finicky.

Little Mermaid Accessories

I didn’t go in with much of a plan for accessories, but I found little bits and bobs while I shopped around town.

I found a fake lily pad at Dressew, and was able to detach the flower and pin it to my hair.

At Spirit Halloween I found a Disney Princess Jewelry Set that came with fork (or Dinglehopper) earrings, and a necklace with a shell on it.

I’m sorry, I scoured the internet for the same set to link for you, but couldn’t find the set.

I also planned to wear a pair of green strappy heels with the look, but I didn’t end up going anywhere… so I have no pictures in them.

And y’all… if I had money-money… I’d go for something like these:


I’m definitely not a makeup artist.
So I’m not going to walk you through my entire makeup look. But there were a couple things I put some extra thought into. I…

  • Used red eyeshadow to colour in my eyebrows.
  • Dusted my lids with purple shimmery eyeshadow.
  • Cut my false eyelashes in half, because I wanted to go for more of a youthful “cute” look, and full eyelashes felt too heavy and sultry.
  • Lined my waterline with white eyeliner to make my eyes appear a bit larger.

Essie had also gifted me some nail polish earlier in the month, and I used two of their shades for what felt like a very-Ariel vibe.

Completed Look: Black Little Mermaid

On Halloween day, my husband and I rushed out to beat the setting sun so I could take some photos by the water.

Here are the results Darren took on his phone:

And here are some of my favourite shots on the camera:

Bonus: The Little Mermaid’s Pink Dress

My original Halloween plan was to change into more comfortable clothing and watch The Little Mermaid.

I used the opportunity to throw on a comfy pink dress, tweak my hair, and do a sort of Disney-bound version of Ariel in her pink dress.

Final Thoughts on my Ariel Halloween Costume
