How to Add a Liner to a Bathing Suit

To add a liner to a bathing suit, you’ll require some measurements and sewing skills. Adding a liner to a bathing suit:
Step 1: Measure the bathing suit
Turn the swimsuit inside out and place it on top of the fabric, then place it on a flat, dry surface. Use tape to measure the crotch piece’s length and add an inch to the measurement. Take the measurement of the Crotch’s center width and add an inch to the measurement.
Step 2: Add an inch to the measurement
Take the measure of the area around the chest of the bathing suit. Write down the measurement of the front neckline from the side to the other side seam. Add an inch to the measurement. Take measurements below the bust line and where you want the bottom liner to be placed on your body.
Measure across the front of the bathing suit from side seam to side seam. Measure the bathing suit’s neckline towards the place on the suit you want to line to sit. Add an inch to the measurement.
Step 3: Sketch out the shape
Place your liner fabric on a flat, dry surface and cross out the crotch liner piece with the crotch measurements you took. Sketch an hourglass shape, making sure the slim center area of the hourglass shape matches the crotch width measurement.
The crotch length measurement should be the same as the top and bottom of the hourglass shape. Ensure that the wider edge of the hourglass shape is 2 inches wider than the slimmest area of the crotch lining.
Step 4: Place the liner fabric across a bikini top
Cross out the bust area on the liner fabric and sketch a shape mimicking the neckline around the top of the liner piece portraying the height measurements. Place the liner fabric across a bikini top and cross out the shape of the bathing suit cup an inch from the bathing suit. However, you will require a two-liner piece of the same fabric and length.
Step 5: Cut out the bust and crotch
Cut the bust and crotch piece and place the crotch piece onto the crotch area of the bathing suit. As you place the crotch piece on the crotch area, ensure you fold the edge of the liner fabric. However, ensure the fabric is placed right along with the bathing suit.
Step 6: Pin the bust in place
While folding the edge of the fabric, pin the bust piece in place. Ensure that the liner is perfectly placed along the neckline of the bathing suit without overshadowing the neckline.
Step 7: Sew it together
Using a sewing machine and a straight stitch, sew the edge of the crotch piece on the curved sides. Take off the pins when sewing. Sew the bust liner and the top neckline with a straight stitch. That’s it; you can turn the right side of the bathing suit out.
