All the mermaid costumes you could buy, in my opinion, hardly resembled a mermaid and looked like a regular dress. So to Pinterest I went, but still no one had made anything I particularly liked. I decided to combine a fabric I saw one place, with a tail I saw another, a shell bra that had a dead link on its tutorial, while also adding my own touches.
Materials I used:
2 Nude Dance Leotards
2 yards of two different colored Tulle
1 yard Fish Scale Fabric from Amazon
1/4 yard Purple Dance Wear Fabric
1 yard Stretchy Purple Sequin material
Some stuffing
Basically I drew my own shells for the bra, sewed right sides together, flipped inside out, stuffed them, sewed them shut and then I hand sewed the lines into the shell bra. After that I attached the bra to the leotards with my machine for duarability and added the sequin material around the back connecting each side of the bra. I cut the leotards in half (horizontally) and serged the edges, cut my mermaid scale fabric, fit it to their waists and sewed it to the leotards. Later I cut the bottom of the scale tail into a triangle and attached straight cut ruffled tulle to the sides of the triangle where I had cut. Last I added tulle to the tops of the tail for a completed look.
The best part is there are no zippers, buttons or snaps, just stretchy goodness. And because they're so stretchy there are no issues with walking or running!
