free tankini pattern + tutorial


I had the opportunity to review Craftsy’s Sewing Fashion Knits class. I learned a lot from it, even though I sew with knits often. There is always something new to learn and I found this course to be an awesome one-stop knit course. You’ll learn everything you need to know to be fully confident sewing knit fabric.  If you are new to sewing knits, Sewing Fashion Knits is the perfect place to start. It is the equivalent of about 50 blog posts all in one video course. The teacher is Linda Lee who did an awesome job explaining things from preparing fabric to finishing seams and hems.

This class covers all the knitty gritty details about knits. Sometimes fabric is hard to sew just because we don’t quite understand it, so this course helps you totally understand different types of knits.

Included in the Sewing Fashion Knits eCourse:
-stabilizing knits
-types of knit fabrics
-hem finishes
-seam finishes, including serger technique
-cutting + marking patterns
-sewing a simple knit garment bonus
+lots more!

This tankini tutorial is an adaptation of my free summer baby dress pattern from last year, but in swimsuit fabric and with a little ruffle sleeve. If you’ve never sewn a swimsuit before, it’s not too hard, especially if you’re sewing for a child. I made this in about 1 hour and it took less than a yard of fabric! I used a thicker swim fabric with a little texture on it. It was super easy! Since this is for a baby I didn’t really need to line it, but I did self-line the top of the bodice.

tankini tutorial

Attach the straps to the bodice by basting them down at the top strap openings. Then sew the back side over the top of the straps and sew the armholes, neckline and top of straps. Turn right side out and repeat with back pieces. Then sew side seams together with right sides together.


Sew skirt panels together at side seams. Then baste top edge with two rows of stitching. Pull threads to gather fabric. Attach to bodice with right sides together. Hem bottom and you’re done!

The bottoms are made using my ruffle diaper cover pattern, but without the ruffle.

  1. […] Kate from See Kate Sew shares a free pattern for making a toddler’s tankini bathing suit.  It’s actually an adaptation of her summer baby dress, and it retains the look and feel of a summer dress.  It has a gathered skirt on an empire waist and little ruffles on the shoulders like flutter sleeves.  Made into two pieces and from a swimsuit fabric, it is super cute for pool time.  Her free pattern will make a size 18/24 months.  If you need another size, you could probably adjust it a size or two pretty easily.  You could also adapt a basic dress pattern that fits your child, using her pattern as a guide.  Go to See Kate Sew for the pattern and tutorial.
