How to Sew a Swimsuit with a Skirted Bottom

Adding a skirt to the bottom of your swimsuit is a great way to give it a bit of personality while also adding a bit of coverage. You can customize the length from cheeky to modest and you can customize the fullness from girly to sporty. You can also easily add a skirt to a bikini bottom or splice it in to a full length suit. So many options! A circle skirt is a great option for the skirted portion of your swimsuit. A half-circle skirt will give you a sporty look (like this sample skirt) and a full circle skirt will give you a more ruffled look. Remember that there is a lot of negative ease in a swimsuit so the skirt fits you more snugly through the top several inches than it would if you were sewing a typical circle skirt. Remember also that the longer your skirt …

Hack the Nautilus Bikini into a High Waist with Twists

At this point in the Swimsuit Sewalong, I’ve sewn a lot of swimsuits. And I think I must say that this hack makes this bikini bottom my favorite. While it’s super easy to turn a basic bikini bottom into a high waist pattern, it turns out that it’s a pretty simple hack to turn the Nautilus Swimsuit View B (the one with the cool twists on the bottom) into a high waist and keep the twists! Yes! Before you do this hack, you probably want to read through the sewalong for View A (the one piece) as the join from top front to top bottom around the twist is very similar to the join for this hack. The first decision you need to make is how much extra height you want to add to the pattern. As written, it’s low rise. I added 3″ to the finished suit to bring …

How to Turn a Swimsuit Pattern into a Tankini

There are many reasons why you might be drawn to a tankini swimsuit, from not having to worry about fitting the length, to the ability to mix and match bottoms, to just plain liking the style. It’s actually remarkably easy to turn a swimsuit pattern into a tankini – read on to learn how! Front: Starting with your swimsuit pattern, draw a line across the front of the suit where you want the bottom of the tankini to be. (Remember that it will end ~1/4 shorter than your line because you need to hem the suit). A good rule of thumb is to slice across where the suit cuts up to go over your hips, but it’s up to you if your personal preference is shorter or longer. You probably want a slight curve to the hem line. Back: Draw a line across the back of your suit that matches …

How to Use a Swimsuit Pattern to Sew Underwear

There are a lot of similarities between a pair of underwear and a bikini bottom, so why not use a sewing pattern for one to make the other? If you’ve got a swimsuit bottom that you like there’s no reason that you can’t use it to make a stack of underwear as well! I’ve put together a few things to keep in mind when doing so – pattern selection, fabric selection, and three different ways to finish the edges of your underwear. Fabric Selection: Swimsuit patterns are designed to be sewn with swimsuit fabrics which have some key characteristics: 4-way stretch, great recovery, and some heft. You clearly don’t want to sew your underwear out of swimsuit fabric, but when you pick a jersey, you should keep these characteristics in mind. You don’t need a 4-way stretch jersey, but you do want to make sure that your jersey has good stretch …

How Hack a High Waist Swimsuit Bottom

High waist swimsuits are a fun way to bring a bit of retro styling to your swimwear. They’re also a great on-trend way to make your swimsuit just a bit more modest. It’s easy to hack your swimsuit pattern into a high-waist bikini bottom regardless of whether you’re starting from a one-piece pattern or a low rise bikini. If you’re starting from one piece pattern, it’s as simple as slicing across the pattern on the front and back pieces where you want the waist to be. The few things to keep in mind: Remember that you have to finish the top of the suit so cut it higher than you want the finished to be (or lower if you want to add a waistband). If you are attaching elastic and folding it to the inside (like most swimsuit finishing techniques) it will only change by 1/4″ but other techniques (like …

Nautilus Swimsuit Sewalong: View C

Sewing the Bikini Bottom for View C of the Nautilus Swimsuit is quick and easy. A nice wham-bam-thank-you-ma’am to finish off the swimsuit!

Nautilus Swimsuit View B

View B of the Nautilus Swimsuit is the bikini versions with sexy twists at hip bone that echo the twist in the center front of the bikini top. At this point in the sewalong you should have read through the various posts on swimsuit sewing techniques and have sewn the swimsuit top with its straps and closure. The steps below are numbered like they are in the written instructions so you can check back and forth. Sewing the twists onto the sides of the Bottom is just like sewing the twist at the center of the Top, so you might want to give the Top Sewalong instructions a quick read-over before sewing the top if you haven’t looked through them recently. [78] Sew the Bottom Front Facings to the Bottom Front Lining on either side, right sides together. Match the notches. When you sew, stop with the needle down at the center …

Installing a Swimsuit Hook and Straps

Sewing clasps and straps onto a swimsuit are often the final finishing touches. There both pretty easy but somehow it’s always the last steps that seem to never get done, or is that just me? While these photographs are from construction of the Nautilus Swimsuit, you can use the same techniques to sew a clasp and straps on to any swimsuit that hooks in the back and has straps that go over the shoulders. If you’re having a hard time sourcing swimsuit hooks, I can suggest 1″ metal clasps that are up for sale in my shop. Sewing a Swimsuit Clasp: Start by threading one arm of your suit back into the closed loop portion of your swimsuit hook. You want the hook to be pointing down. Depending upon the width of your back and the width of your clasp, you may have to gather your back a little in to the clasp. …

How to Insert Bra Cups into a Swimsuit

Adding cups to a swimsuit pattern is actually an easy modification that can make your suit instantly more supportive and comfortable. It’s pretty easy to slip swimsuit or bra cups into a suit or with a bit more work you can even add a cup with an underwire! Choosing cups: There are many kinds of different bra cups out the biggest consideration you need to make is whether it’s the type of cup that is comfortable to you. You can buy softer cups that don’t give a lot of support but do provide a bit of modesty. Foam cups are a great choice for both support and modesty. If your foam cups aren’t specifically labeled for swimsuits, make sure that they don’t retain a lot of water like a sponge when they are wet! I find one of the best ways to source cups is to go to a thrift …

How to Add a Contrast or Finished Edge to a Swimsuit

The standard for both ready-to-wear and handmade swimsuits is to sew elastic to the inside, fold it over, and sew another line of stitching to keep it in place. For an alternative, you can add a bit of extra pizzazz to your suit with a contrast edging using one of two different techniques – fabric strips or fold over elastic. Additionally, you can use either technique to get a much cleaner finish on the inside than you can with the traditional technique. Before getting started with this finished edge tutorial, make sure you have read How to Sew Elastic to a Swimsuit. Note: Both of these techniques increases the size of each finished piece when compared to the traditional way of folding the elastic to the inside. Why is that? You lose 1/4″ from every edge when you fold the elastic to the inside. When you use the fabric strip …

Sewing Elastic to a Swimsuit

For most swimsuits, ready-to-wear or handmade, the edges of the swimsuit are stabilized and finished with elastic. The elastic is sewn to the inside of the suit and then folded over and topstitched. It’s really quite simple to do and with a few extra tips and tricks, you can have a perfectly awesome elastic insertion on your own swimsuit! Stitches: When you sew the elastic to the inside of your swimsuit, you should use a wide zig-zag. If you have a stretch zig-zag stitch on your machine, this is a great place to use it. If not, use your normal zig-zag on its widest setting. This will securely attach the elastic to the suit and allow it to stretch. When you fold the elastic over, you can use the same wide zig-zag, a narrower zig-zag, or a straight stretch stitch (also called a lightning stitch) depending upon how you want …

Fitting & Grading the Nautilus Swimsuit

The principles of fitting and grading any swimsuit are pretty similar, so no matter what pattern you are using, you’ll hopefully find some helpful information to fit and grade any swimsuit sewing pattern amongst the specific example of the Nautilus Swimsuit. Before you start any fitting and grading, make sure you are starting with the best base size by reading How to Choose a Swimsuit Pattern Size. Cup Size: The Nautilus Swimsuit pattern has 4 different cup size options ranging from AA to DD+. Measure the difference between your full bust and your under bust to get your suggested size. 0-1″ = AA, 1-3″ = A/B, 3-5″ = C/D, and >5″ = DD+. However, this is just a starting point (like any other sizing) and you will want to make a muslin to determine that you are getting a proper fit. What might cause the wrong fit? The cups on …

How to Choose a Size on a Swimsuit Pattern

When I’m sewing a pattern that I haven’t sewn before, I usually jump straight to the pattern pieces and measure the high bust and the hip to choose what size I will sew. Patterns often don’t list their finished measurements and sizing charts often don’t say how much ease they include but a pattern piece reveals all. However, this technique falls apart when selecting a swimsuit size for many reasons. Below, I’ll detail these reasons and explain what to consider instead so that you can best select the size of your swimsuit sewing pattern. Note: Like any sewing pattern, when sewing a swimsuit you can have a pretty good guess about the right size to start with, but you are well served to make a muslin and use that to fit adjustments specific to your body. Ease: For fitted garments with stretch, 0-2 inches of negative ease gives a pretty …

How to Choose Swimsuit Fabric

With all of the amazing looking swimsuit fabrics out there, it can be a bit intimidating to actually choose a fabric. “What are the kind of things to look for when I buy swimsuit fabric?” you might be asking. Well, have no fear – I’m here to tell you! At least I’m here to show you the sorts of things that I look for when I buy swimsuit fabric. If there’s something you look for that I haven’t included, please chime in in the comments! Fiber Content: The first thing that I look for is fiber content. Note that there can be a fair bit of variety in the names used to label the synthetic fibers and many of them mean the same thing. Swimsuit fabric is almost always 80-90% polyamid, polyester, nylon, or another similar synthetic fiber. The other 10-20% is spandex, lycra, or elastane (all of which are …
