Costume Information

Since I have finally sold my old Ariel fin, I figured it was about that time that I worked on a new one. The one I used had become quite worn out since I had worn it to pretty much every con that I've been to and it desperately needed an upgrade.

I've been playing around with trying to make my new one a hybrid design( Swimmable and Walkable) and I think I may have cracked the secret. Of course I took a lot of inspiration from a lot of fellow mermaids out there and just smashing all together into something I find aesthetically pleasing :3

The tail is mostly made out of neoprene, however the neoprene I bought originally was dark purple. So I played around with some painting techniques and came up with something that was both pretty as well as harkening back to the true spirit of the film. I did my best to research the colors used in the animated film but since I couldn't find an exact color swatch from the Disney paint lab, I mixed a myriad of color schemes and kind of made my own thing with it. While the paint was still wet I dusted the entire tail with 2 different types glitter: A thin mint green glitter and a chunkier blue/ green glitter (ironically with the name "Mermaid." Go figure). I also added a few rhinestones on the fin to give the appearance of water droplets

To-Do List

We're very sorry, but we've temporarily disabled this feature while we fix some bugs. Thank you for your patience.


The Moment of Truth (Posted 16th February 2015)

Okay....Here we go :)
The tail is finally complete. Now it's the time to test it's durability. I'm not sure what'll come of this whole testing process, but with all hope, the tail will last. If not, at least I've got good pictures of it to remind me of what a good job I did before trying a new method :) Whatever happens, happy swimming

Currently On Hold :( (Posted 3rd January 2015)

There were a few flaws in my original design. I want this tail to be multi-functional for both cons and for mermaiding so I'm going back and reevaluating the design to allow that. I want this fin to be perfect in my own eyes and I will strive to make this to the best of my ability. I'll definitely wear it for later cons and photoshoots :3

Possible new shells (Posted 8th December 2014)

I've wanted to get Disney park inspired shells for eons now :D Lucky for me that angel-secret finally started selling the park shells. I'm thinking of getting them in white so I can paint them myself since their purple looks really awkward :-;

Tail Painting (Posted 1st December 2014)

So I got the front somewhat painted similar to my test swatch :D
I'm extremely pleased with the colors I chose and I'm very proud of this. It's now the perfect shade of Ariel green~

I have glitter all over my floor but it was totally worth the mess :3

The scales are there, they just don't show up as well on camera.

Finally Making Scales (Posted 18th November 2014)

I finally started drawing the scales on my tail :)
I've gotten halfway through the front of the scales in 2 days, GO ME! :D I'm so excited with each new scale I make.

Scale Test (Posted 2nd November 2014)

So I've been just cutting scraps of the neoprene and testing the painting on it. I'm aiming to get a color similar to Traci Hines's new tail that she uses for her music video (That movie accurate sort of green blue) but it's been kind of difficult. This was my failed test but I think I know what colors I'll be using. I'll also be stenciling the scales on instead to make them more durable.

New Wig :) (Posted 3rd December 2013)

It's about time I say goodbye to another little mermaid wig that I've been using :( After cutting it to a reasonable length and trying to style it again after washing it was not the easiest thing. It's pretty much unstylable now but the good thing about this one is that it's heat resistant so if I wanted too I would use a curling wand on this one :)


Finally found the perfect fabric (Posted 3rd December 2013)

I managed to get super lucky and I found the exact fabric that the Disney parks mermaid tail has. It's a fish scale-esque sequin fabric that has a very beautiful shimmer to it. It even changes color in the light XDD I might have to line it though because it's going to be really itchy fabric Dx I'm kind of thinking I'm going to regret this decision later when I'm sewing it :/
