“Mom! I love it! You’re a fat mermaid!”

Special thanks to JOANN Fabrics for partnering with me on this DIY mermaid costume post. While I was compensated to share on my social media channels, I was not compensated to post this on my blog.  I just thought it was pretty fun and wanted to share it with you!

“Mom! I love it! You’re a fat mermaid!”

That was my son’s response to this costume. I was dying with laughter. Pregnant mermaids might not really be a thing, but I sure had fun making this ensemble! I was inspired by the sweet new fabrics that JOANN Stores are currently carrying under their YaYa Han Collection.  I also liked the challenge of making the whole pregnant-mermaid thing work.  People thought I was crazy, and I kind of was, but the end turned out pretty fun in my opinion.

I made two different versions of this diy mermaid costume–one for really festive parties, and a more casual one I’ll probably be wearing most of the time.  The best part about these costumes is that they work just as well for maternity as non-maternity.  (Though you might want a different phrase on your t-shirt if you’re not pregnant.)

DIY Mermaid Costume

For this specific project, I used three different fabrics from Yaya’s line:

• Mermaid Poly Spandex (skirt)
• Green Oil Slick (belt)
• Metallic Turquoise 4-way stretch (sweetheart top)

I used the this pattern for the skirt, and this one for the top.  I made a few alterations to accommodate my pregnant belly, but the stretch factor of the fabric made this relatively easy.

I also picked up some shells and knick-knacks while I was there to make a mermaid crown to complete the look (tutorial to come).

For more casual Halloween events, I made a t-shirt using my Cricut machine to cut out the phrase “SEAriously Pregnant” next to an image of a pregnant mermaid.  I designed it using Canva, which is a free online design tool. You can get all the cricut supplies I used from JOANN as well—they’ve got ya covered.

Overall, I’m pretty excited about how this turned out, but mostly just relieved that it will continue to stretch as I do in the upcoming months. Halloween is going to be pretty fun this year.
