Bonus: How to Sew a Swimwear? A Step-by-Step Guide

Sewing your own swimwear can be a rewarding and empowering experience. This guide will help you through the process of sewing your own swimsuit, from fabric selection to basic construction techniques. Let’s dive in!

Step 1: Fabric Selection

Choose a fabric with ample stretch, as swimwear patterns are designed with negative ease. Two-way stretch fabric is suitable for two-piece suits, while four-way stretch fabric works best for one-piece maillots and two-piece suits. Opt for swimwear fabric composed of man-made fibers like nylon, with around 10-20% Lycra or spandex for stretch.

Step 2: Notions

Swimwear elastic is essential for shaping and securing the garment. Look for cotton swimwear elastic, which withstands chlorinated and saltwater. Rubber elastic is an alternative, offering a lower profile and less bulk. Use polyester thread and ballpoint or jersey needles for sewing swimwear fabric. Foam cups designed for swimwear provide support and coverage.

Step 3: Cutting

Swimwear Fabric Cutting, slinky swimwear fabric, can be tricky. Cut single layers whenever possible to maintain control. Cut with the right side facing up to ensure proper print placement if using printed fabric. Consider using a rotary cutter and pattern weights for precision. Pay attention to the grainline and cut your pattern pieces accordingly.

Step 4: Construction Techniques – Seaming

Use a serger or a domestic sewing machine for construction—Serge the swimwear fabric right sides together with a 3/8 inch seam allowance. If using a sewing machine, use a wide, short zigzag or mock overlock stitch. Test your stitch on a scrap fabric and stretch it to ensure adequate strength and stretch.

Step 5: Construction Techniques – Basting

Basting may be required to join layers of fabric. Place the main fabric and lining fabric wrong sides together, clip them in place, and baste using a wide zigzag stitch.

Step 6: Construction Techniques – Elastic

Finish Elastic is typically used to finish the edges of swimwear. The sewn-and-turned method is commonly employed.

Attach the elastic to the wrong side of the raw edge, serge or zigzag overcast the elastic and fabric together, then turn the elastic to the wrong side and topstitch in place using a standard or three-step zigzag stitch. Stretch the fabric evenly as you sew.

Step 7: Construction Techniques – Elastic in a Seam

In some cases, elastic is added to a seam for extra support. Sew the seam using a serger or zigzag stitch, then attach the elastic to the seam allowance using a zigzag stitch, stretching evenly as you sew. Turn the unit right side out to admire your supportive seam.
