How to make a swimsuit?


Are you ready to try your hand at sewing swimwear? I adore making swimsuits, but I understand that it can be a daunting endeavor for novices who are unfamiliar with sewing high-stretch fabrics or swim fabrics. The good and pure news is that sewing a swimsuit is easier than you might think, and it can be quite satisfying to eventually produce that dream one-piece or bikini for yourself. It's also a lot of fun! All you need are the correct supplies, methods, and a little patience to make your own swimwear.

Part 1: Putting the Suit Panels Together

One of the great things about swimsuits is that they are so versatile. You can wear them to the pool, beach, or even just around town. And making your own swimsuit is a fun project that you can do with friends or family. In this blog post, we'll show you how to put the suit panels together to make a swimsuit. Let's get started!

Step 1. Purchase Or Construct A Front And Back One-Piece Swimsuit Pattern

Swimsuit patterns are easy to find online or in craft stores; they're made of paper, and if you cut them in half vertically, each panel (front and back) looks like that side of the bathing suit. Make your own pattern according to your imagination by folding a swimsuit vertically in half, tracing the outline on craft paper, and then folding it vertically the opposite way and tracing it on another sheet of paper or scrap fabric.

Pre-made patterns include guidelines that allow you to adjust the suit's size or cut as needed. You can simply add to, cut from, or subtly modify the shape or design of the outfit if you make your own pattern pieces. Swimsuits are rubber elastic and should have "negative ease," which means the pattern you choose should be 3–5 inches (7.6–12.7 cm) smaller than the body measurements of the person you're creating it for.

Step 2. Purchase Swimsuit Materials And Linings, As Well As Swimsuit Elastic

Make sure you get a swimsuit fabric with a 4-way stretch, which can extend both vertically and horizontally, as opposed to a 2-way stretch, which can only stretch horizontally. Choose either a swimsuit lining fabric or a neutral-colored swimwear fabric with a 4-way stretch for the lining. Purchase a roll of swimsuit elastic as well (not standard elastic).

Swimsuit fabric is often made up of 80 percent to 90 percent nylon and 10 percent to 20% lycra or spandex. 2-way stretch fabric is acceptable for 2-piece swimsuits, but the 4-way stretch is ideal for 2-piece suits and required for 1-piece suits. Otherwise, your one-piece suit will be too tight to put on! S Swimsuit elastic is made of cotton or rubber rather than polyester and is designed to withstand chlorine and seawater.

Step 3. Lay Out Two Pieces Of Swimsuit And Liner Fabric And Fold Them Over

Smooth out the two pieces of swimsuit fabric, pattern side down. Fold each piece in half, making a straight fold line along one edge as if you were shutting a book. Repeat with the lining fabric (bearing in mind that it does not have a design side). Each piece of fabric should be somewhat larger than the swimsuit design panels when folded in half.

Step 4. Trace And Cut The Swimsuit Panels Using The Patterns

Place the front and back panel patterns on their corresponding pieces of swimsuit fabric, with the pattern's straight edge (that runs from the neck opening to the crotch) directly on top of the fabric's folded edge. At this step, you have two options: trace the design onto the cloth with chalk and then cut it out, or simply cut out the pattern outline with sharp scissors or a rotary cutting wheel. Replace the lining fabric and repeat the process. When cutting the fabric, don't stretch it. If desired, use pins or fabric weights, or pattern weights to keep the pattern in place during tracing and/or cutting.

Step 5. Unfold The Cut Panels And Lay Them Out Inside-Out

In other words, unfold and put down the suit material's back panel with the patterned side facing up on your work surface, then lay the front panel on top of it with the patterned side facing down. Make sure the unfolded panels, especially the shoulder straps, sides, and crotch area, are smoothed out and aligned properly. Do the same with the front and back liner panels. However, there's no need to worry about the "right" and "wrong" sides of the cloth in this case!

Step 6. Use A Zig Zag Stitch To Sew The Tops Of The Straps, The Sides, And The Crotch

Set your sewing machine to apply a standard zigzag, three-stretch zigzag, or lightning stitch using either a ballpoint or stretch needle. Sew together the tops of the shoulder straps, the sides of the suit between the arm and leg openings, and the crotch area between the leg openings right now. Separate the front and rear liner panels and repeat the process. You'll be attaching the suit and liner materials soon. Stretching is significantly easier using zigzag sewing patterns. Just follow pattern instructions. Use polyester or wooly nylon thread for this project. Cotton thread is not elastic enough and does not withstand chlorinated or salty well.

Step 7. Inside The Swimsuit, Baste (Temporarily Stitch) The Liner

Align the seams clarefuly you just stitched in each and start with the crotch seam, then the side seams, and finally the strap seams—by slipping the liner into the suit material at the neck opening. As you align the linked seams, pin them in place. Set your sewing machine to a basic basting stitch, which is a simple up-and-down running thread. Stitch the neck, arm, and leg openings of the liner and suit together.

Tacking is another name for basting. In this situation, you don't need to remove the basting stitches once the suit is finished. If you choose to do so, wait until the suit is completely finished before slicing through the basting thread and pulling it out with a seam ripper.

Part 2: Making the Suit More Elastic

The second step to making a good swimsuit is to make the suit more elastic. Adding more elasticity will help keep the swimsuit in shape and will make it more comfortable to wear. There are several ways to add elasticity to a swimsuit, and each method has its own advantages and disadvantages. There are three methods of adding elasticity to a swimsuit: using an elastic band, using a lace insert, and using power netting. Now that we have the pattern for our swimsuit, it's time to make it more elastic. This will help ensure that the swimsuit fits well and looks great on your body. Follow these simple steps to make your swimsuit more elastic.

Step 1. Sew Swimsuit Elastic With A 25% Stretch Into The Neck Opening

Turn the suit inside out and tuck the elastic strip into the center back of the neck opening. To keep the elastic in place, make 5-10 zigzag stitches using your sewing machine. Stretch the elastic to 5 in (13 cm) from where you grabbed it, approximately 4 in (10 cm) along the strip—this is a 25% stretch. Stitch the stretched length of elastic to the inside of the neck opening with the zigzag stitch, then repeat the technique with the elastic further down the strip. Continue until the elastic is completely wrapped around the inside of the neck opening. Only the elastic strip should be stretched, not the swimsuit or liner fabric.

Step 2. Stretch The Arm Holes With Elastic At A 25% Stretch

Starting about the middle of the backside of the shoulder strap, repeat the neck opening method. Continue stretching, zigzagging, sewing, and repeating until each arm opening is completely covered. While stitching the elastic into place, keep in mind to stretch only the elastic, not the suit cloth. Yes, sewing on the elastic is one of the trickiest parts of constructing the swimsuit, if not the trickiest. However, the elastic is more forgiving than you may think—you don't have to maintain a precise 25 percent stretch—and any big mistakes are quite straightforward to reverse and repeat. So keep going with a positive attitude!

Step 3. Sew Elastic At Both A 25% And A 75% Stretch Into The Leg Holes

The elastic on the backside of the leg holes should be squished together more tightly. Sew halfway around the leg opening or on the exact front side of the suit at a 25% stretch, starting immediately in front of the seam at the crotch. Pull the elastic to about a 75 percent stretch to go the rest of the way around (on the back side of the suit)—for example, stretch a 4 in (10 cm) same length of elastic to 7 in (18 cm).

Step 4. Topstitch With A Second Thread And Twin Needle

Now, Stack a second spool thread on top of the first using the adaptor that came with your machine. Then, just like with the first line, feed the second line of thread through the machine to load it. Replace the machine's single needle with a double-needle and thread both lines of thread through it. Twin needles can be found in any sewing supply store. They resemble two-tined pitchforks! Twin needles sew in two parallel lines, providing strength and a finished appearance.

Step 5. Using The Twin Needle, Topstitch The Elastic Bands Into The Suit

Fold-over the edge of the suit fabric where it's attached to the elastic band with the suit right-side out. As you feed the folded fabric through the machine, use your fingers to keep it smooth and taut, then secure it with a zigzag stitch or another strong yet flexible finishing stitch. Using elastic, repeat the technique on all portions of the suit. Congratulations on completing the suit's final stitch! As you secure the topstitch in place, don't stretch out the elastic. To smooth out any wrinkles or bunching, simply pull it taut. The elastic bands are topstitched to keep them in place and make the suit more comfortable to wear.
