DIY Mermaid Costume – Video Tutorial

Have you made your kids Halloween costumes yet? Are you at lost for ideas and looking for a quick sew.  Celina from the Sewing Rabbit team has just what you need! An easy and super cute mermaid costume, something your kids will love and play with for hours… Nothing like a great last minute project, right?

DIY Mermaid Costume

You will need some organza in 5 different shades to create the mermaid tail and a tiny bit of jersey for the bikini top. Best part? It should take you about 1 hour and half from cutting to sewing and dressing up!
I’ve created an animated video for the tutorial… just a few steps and you’ll be done in a jiffy. Yay!

You might need to adjust a little ( more fabric for your fish scales)  if you are making this in a bigger size than a 4T, but all in all you will get the idea.
1, 2, 3… easy enough even for a beginner. The shine and transparency of the organza adds a lot to the design. However you could do this with some felt and even skip adding the extra fabric layer…

Add a few elements from your closet, such as tights & a leotard. Have a little fun with a wig too…

My daughter loves Ariel from The Little Mermaid, so I matched the colors to resemble hers.

Happy Halloween!!!  Thanks so much for stopping by, and until next time…

Happy Sewing!

    Thank you so much for posting this tutorial. I’m sharing the link with our children’s performance arts troupe, hoping to inspire their creativity, as we approach the summer season in the North Country. Northern New York is a splendid place to live; but, we NEED more mermaids. :D
