  • 1 yard of swimwear fabric (nylon-spandex, poly-spandex, etc..)
  • Swimwear elastic
  • Overlock machine (recommended, but if you don't have one use a zig zag stitch on a regular sewing machine)
  • Poppy One Piece PDF Pattern (see below)

Step 1

Cut your pieces. You'll cut two of Piece 1 and two of Piece 2. If you are using a different fabric for your lining, you'll cut one in the self and one in the lining for each piece.

Seam allowance is not included in the pattern, so cut leaving 1/4".

Step 2

Match up your two front pieces, with right sides together. Do the same with your two back pieces. Pin all around every open edge, just leaving the sides, gusset, and strap openings untouched. Once you've pinned, sew. You'll be sewing the arm holes, neckline, and leg holes for both the front and the back.

Also at this step, attach your elastic. If you have an elastic foot you can complete this in one step, but if you don't have one then break this step into two steps. First sew the fabric together, then go back right where you just sewed and attach elastic.

Use a 4-thread overlock stitch, or a zig zag stitch.

Step 3

Now flip the front piece to the right side. Keep the back piece inside out. Insert the front piece INSIDE of the back piece, making sure the right sides are matched together. Line the front piece up into the back piece so that the straps, sides, and gusset are all lined up. Pin the gussets, straps, and sides together. When you sew, you should be sewing all four layers of fabric.

Step 4

Seam rip a hole about 1.5" in the low back area of the back piece, where the clothing tag would usually go. Secure this hole with your machine if needed to ensure the seams don't come unraveled.

Step 5

Through the seam ripped hole, bring the entire suit back to the right side.

Step 6

Finally, finish off the seam ripped hole using an invisible stitch or top stitch.
