Sewing swimwear is not only a rewarding project, but it requires some specific techniques and considerations due to the nature of the fabric and the intended use of the garment. Here are some top tips for sewing swimwear:

 

Choose the Right Fabric

 

Choosing the right fabric is crucial when sewing swimwear, as it directly impacts the fit, comfort, and durability of the final garment. First, the fabric should have a 4-way stretch, meaning it stretches both horizontally and vertically. It is essential for swimwear to comfortably conform to the body's curves and movements. Second, choose good recovery fabric, it refers to how well the fabric bounces back to its original shape after being stretched. A high-quality swimwear fabric should have excellent recovery to prevent sagging and distortion over time. Finally, before purchasing the fabric, perform a stretch test by gently pulling it in both directions. The fabric should stretch smoothly and evenly without distorting or losing its shape.

 

Use the Right Needles and Thread

 

When sewing swimwear, use a size 11 or 14 stretch needle to prevent damage to the fabric. Opt for a polyester thread with good elasticity and resistance to chlorine and saltwater.

 

Use a variety of sewing methods

 

 Most modern sewing machines have stretch stitch options, such as a lightning bolt stitch or a triple straight stitch. These stitches allow the seams to stretch without breaking.

Use Elastic

 

Choose swimwear elastic that is chlorine-resistant and has good stretch and recovery. For leg openings and waistbands, use a narrower elastic (around 1/4 inch wide), and for areas like necklines and armholes, use a wider elastic (around 1/2 inch wide).

 

Practice Good Finishing Techniques

 

Consider using a serger or overlock machine to finish raw edges and prevent fraying. For enclosed seams, sew the main fabric and lining fabric with right sides together, and then flip the seam allowance to the inside.

 

Avoid Bulk

 

Trim seam allowances to reduce bulk, especially in areas where multiple layers of fabric come together, such as at leg openings or waistbands. Use a rotary cutter and cutting mat for precision trimming.

Test before Sewing

 

Make a muslin or test garment using a similar stretch fabric to ensure the fit and construction are correct before cutting into your main fabric. Adjust the pattern as needed based on the test garment.

 

Use a Walking Foot

 

A walking foot helps feed both layers of fabric evenly through the machine, preventing one layer from stretching more than the other. This is especially helpful when sewing swimwear with slippery or stretchy fabrics.

Consider Pattern Placement

 

Pay attention to the direction of stretch in the fabric when cutting out pattern pieces. Align the grainline of the pattern with the greatest stretch of the fabric for a comfortable and flattering fit.

 

Care Instructions

 

Include care labels in your swimwear with instructions for hand washing in cold water with mild detergent, avoiding bleach, and laying flat to dry. Proper care will help maintain the elasticity and color of the fabric over time.
