How To Make a Mermaid Skirt

August 29th, 2014 | Learn How, Sewing

Since attending the Barbie and the Pearl Princess movie premiere and watching The Little Mermaid countless times my daughter has been obsessed with Mermaids. So when her birthday rolled around a few weeks back, it was only natural she wanted to have a mermaid party. What is a mermaid without a beautiful fin, or in our case a Mermaid skirt?! These mermaid skirts are super easy to create, a perfect beginner sewing project.

You will need these supplies to create your own Mermaid skirts-

  • Stretch fabric, I used dress lining because it was only $1.99 a meter, but jersey, or other knits will work fine.
  • Sparkly fabric, again I used what was on sale, but there are lots to choose from in the party and formal wear section.
  • Stick pins
  • sewing machine, serger if you have access to one, or a zig zag stitch will work fine.

Fabric cuts- 

  • Small (age 4-5),-  skirt 2 pieces 14″ x9″ | waist– 5″ x 18″ | Sparkly Fabric 2 pieces 54″ x 6″
  • Medium (age 6-7)- skirt 18″x 10″ 2 pieces | waist– 5″ x 20″ | Sparkly Fabric 2 pieces 54″ x 7″
  • Large (age 9-10)-  skirt 20″x 12″ 2 pieces | waist– 6″ x 23″ | Sparkly Fabric 2 pieces 54″ x 8″

    How To Make A Mermaid Skirt


  1. Cut 2 rectangles from the knit fabric.
  2. Fold in half lengthwise. Measure up 6″ from the bottom outside corner, cut from that point to the fold, cutting off a triangle to create a point.
  3. Ruffle the 2 pieces of sparkly fabric individually stitching the top edge. See this post on I heart Naptime if you’re new to ruffling fabric.
  4. Line up the sparkly ruffle with the pointed end on each of the skirt pieces. Pin and baste in place.
  5. Serge or zigzag stitch along the raw edge of each skirt piece joining the stretch and sparkly fabric.
  6. Place the two skirt pieces together right sides together. Baste and lock edges to create a skirt.
  7. Fold the waist piece in half lengthways and stitch end to create a circle. Fold circle in half widthwise and place overtop the end of the waist of the skirt lining up raw edges.
  8. Serge or zigzag around the raw edges of the waistband. Flip upwards. Trim treads to complete.
  9. Add embellishment to waist if desired.


These Mermaid skirts are perfect for dress-up, birthday parties, and even Halloween costumes!

Aren’t they incredibly sweet on the little mermaids?! When standing the Mermaid skirts are ankle length so just the feet are poking out.
