Ripple Swim Skirt – Free Crochet Pattern Guide (From Summer Crochet by Knits ‘N Knots)

If you’ve been searching for a crochet swim skirt pattern that’s beginner-friendly, stylish, and perfect for summer, you’ve found exactly what you’re looking for. The Ripple Swim Skirt is one of the most beloved designs from the book Summer Crochet by Knits ‘N Knots, and it’s easy to see why. With its flowing ripple stitch, quick construction, and beachy charm, this skirt has become a go-to project for crocheters who want to look gorgeous poolside without spending weeks on a complicated pattern.

In this post, I’m walking you through everything you need to know about this pattern — from the materials and skills you’ll need to tips for customizing it, caring for it, and styling it for your next beach day or backyard pool party. Whether you already own Summer Crochet and want a little extra guidance, or you’re just discovering it for the first time, this guide is for you.

What Is the Ripple Swim Skirt?

The Ripple Swim Skirt is a crocheted cover-up skirt designed to be worn over a swimsuit. It features the classic ripple stitch — sometimes called the chevron stitch — which creates a gorgeous wavy, textured fabric that flows beautifully when you walk. The skirt sits at the waist, falls to a flattering mid-thigh or lower length depending on your gauge and sizing, and is finished with a simple waistband that sits comfortably and securely.

What makes this pattern special is how wearable it actually is. This isn’t a decorative piece that looks pretty on a hanger but feels awkward to wear. The construction is thoughtfully designed so the ripple pattern creates natural stretch and drape, making the skirt comfortable and flattering across a wide range of body types. It’s also genuinely functional — lightweight and quick-drying, so you can throw it on right after stepping out of the water without worrying about it becoming heavy or uncomfortable.

The pattern appears in the book Summer Crochet by Knits ‘N Knots, a collection of crochet designs built specifically around warm-weather living. If you haven’t picked up your copy yet, this pattern alone makes it worth it.

Why Crochet a Swim Skirt?

Before we get into the pattern details, let’s talk about why making your own crochet swim skirt is such a great idea.

First, there’s the fit. Ready-to-wear swimwear cover-ups are made to fit a specific size standard, and most of us know that swimwear sizing can be an exercise in frustration. When you crochet your own swim skirt, you control the sizing from the start. You can add or subtract length, adjust the waist circumference, and customize the fit to your actual body rather than hoping something off the rack works.

Second, there’s the quality. A handmade crochet skirt made from quality yarn will outlast almost anything you’d buy at a discount swimwear retailer. If you invest in a good cotton or cotton-blend yarn and crochet with consistent tension, the resulting skirt will hold its shape wash after wash, season after season.

Third — and this is honestly the most fun reason — there’s the color. You can make this skirt in any color combination you want. Want a bold tropical print effect? Choose two or three variegated yarns and alternate them between rows. Want something minimalist and chic? Pick a single neutral like ivory, sand, or sage green. Want to match your swimsuit exactly? Bring a swatch of your suit fabric to the yarn shop and find the perfect match. The creative freedom you have when you’re making the piece yourself is unbeatable.

Finally, a crochet swim skirt makes an incredibly thoughtful handmade gift. Birthdays, bachelorette trips, girlfriend getaways — a custom-made swim skirt in someone’s favorite colors is the kind of gift that people genuinely treasure.

Materials You’ll Need

The Ripple Swim Skirt from Summer Crochet is designed to be worked in a lightweight, quick-drying yarn, which is important since this is a garment you’ll be wearing near water. Here’s what you’ll generally need to get started. Always refer to the pattern in your copy of the book for the exact yarn weights, hook sizes, and yardage requirements for your chosen size.

Yarn: A cotton or cotton-blend yarn is ideal for this project. Cotton is naturally moisture-wicking, dries quickly, doesn’t hold onto pool chemicals the way some synthetics can, and has a lovely drape that works beautifully with the ripple stitch. Look for something labeled DK weight or light worsted, depending on the size version you’re making. Bamboo-cotton blends are also wonderful for this project because they add a subtle sheen and extra softness.

Hook: The hook size will correspond to your yarn weight. A 4.0mm to 5.0mm hook is typical for the yarn weights used in this pattern, but always check your gauge before starting.

Notions: You’ll need a yarn needle for weaving in ends, scissors, stitch markers, and a measuring tape. If the pattern calls for an elastic waistband, you’ll also need a length of non-roll elastic and a safety pin to thread it through.

Gauge: This is non-negotiable for a garment pattern. Take the time to make your gauge swatch, wash it, dry it flat, and measure it before casting on. Garment fit depends entirely on hitting the correct gauge, and a swim skirt that’s too wide or too narrow won’t look or feel the way it should. A few extra minutes spent on a gauge swatch saves hours of frustration later.

Skills You’ll Need

One of the most appealing things about the Ripple Swim Skirt pattern is that it’s genuinely accessible. You don’t need to be an advanced crocheter to make it. If you’re comfortable with the following basic skills, you’re ready to start:

Chain stitch (ch): The foundation of almost every crochet project. The skirt begins with a foundation chain.

Single crochet (sc): Used in various parts of the construction and finishing.

Double crochet (dc): The workhorse stitch of the ripple pattern. If you can work a clean double crochet, you’ll have no trouble with this skirt.

Ripple/Chevron stitch: The ripple stitch is simply a repeating pattern of increases and decreases that creates the wavy effect. It sounds more complicated than it is — once you’ve worked one full repeat, you’ll find it becomes rhythmic and almost meditative. Many crocheters say ripple stitch projects are the ones they reach for when they want to relax because the pattern becomes so intuitive.

Joining rounds: If the skirt is worked in the round (which creates a seamless finish), you’ll need to be comfortable with slip-stitch joins and turning chains.

Weaving in ends: Because color changes or yarn joins create multiple ends, comfortable end-weaving is helpful.

That’s genuinely the whole skills list. No complex shaping, no colorwork techniques beyond simple color changes, no specialty stitches. This is a project that’s well within reach for an adventurous beginner or a comfortable intermediate crocheter.

Understanding the Ripple Stitch

Let’s spend a moment talking about the ripple stitch itself, because understanding why it works the way it does will help you troubleshoot if something looks off.

The ripple stitch creates its characteristic wave by alternating increases and decreases across a row or round. A typical ripple repeat might look like this: work several double crochets into one stitch (creating a peak), work across several stitches normally, then skip or work decreases over stitches (creating a valley), then work across normally again before hitting the next peak. This push-pull rhythm of increases and decreases is what makes the fabric ripple.

The key to a beautiful, even ripple is consistency. Your increases need to be consistently placed, and your decreases need to be consistently placed. If you drop or add a stitch somewhere in the middle, the ripple will shift, and you’ll notice it immediately because the wave pattern won’t align from row to row. This is why stitch markers are so helpful — marking your peak and valley stitches at the beginning gives you visual reference points as you work across.

If your ripple is looking more like a gentle wobble than a dramatic wave, check your tension. A looser tension exaggerates the ripple effect beautifully, while a tight tension compresses it. For a swim skirt that flows and moves, you generally want a slightly relaxed tension — not so loose that the fabric is floppy, but loose enough that it has drape.

Customizing Your Ripple Swim Skirt

One of the greatest joys of crochet is that patterns are starting points, not rigid rules. Here are some ways you can personalize the Ripple Swim Skirt to make it completely your own.

Length: Want a longer skirt that hits at the knee? Simply add additional rows or rounds to the body of the skirt before working the border. Want a shorter, flirtier mini? Stop a few rows earlier. The beauty of the ripple pattern is that it looks intentional and finished at almost any length because the wave creates a natural visual conclusion.

Color: The ripple stitch was practically born for colorwork. Try working each row or round in a different color for a rainbow effect. Alternate between two colors for a bold stripe pattern. Use a single variegated yarn and let the color do all the work for you. If you’re using the book’s pattern, you can follow the colorway shown in the photos or branch out entirely.

Waistband style: The pattern includes instructions for finishing the waist, but you have options here too. A simple folded hem with elastic threaded through it gives a clean, comfortable finish. A crocheted drawstring waist adds a boho touch. A wide ribbed waistband adds structure and defines the waist more dramatically. Consider what you like most in your everyday clothing and apply that preference here.

Border: Adding a simple border along the hem of the skirt — even just a round of single crochet or a shell stitch border — gives the finished edge a polished, professional look and can add a lovely decorative touch that makes the skirt feel truly custom.

Size adjustments: Ripple stitch patterns are adjusted by changing the number of pattern repeats in your foundation chain. Adding one full repeat widens the skirt; removing one narrows it. This makes size adjustment relatively straightforward, as long as you stay consistent with your gauge.

Caring for Your Crochet Swim Skirt

A handmade crochet garment deserves a little extra care to keep it looking its best for as long as possible.

After swimming — especially in chlorinated pool water or saltwater — rinse your skirt thoroughly in cool, clean water as soon as you can. Both chlorine and salt can break down yarn fibers over time, so rinsing immediately after exposure will significantly extend the life of your skirt.

When it’s time to wash, hand washing is always the gentlest option. Use a mild detergent or a delicate wool wash (even for cotton yarns, these gentle formulas are kinder than regular laundry detergent). Submerge the skirt in cool water, gently agitate it, and rinse thoroughly until the water runs clear. Do not wring it out — instead, press excess water out gently between your hands, then roll the skirt in a clean towel to absorb more moisture.

Dry your skirt flat whenever possible. Hanging a wet crocheted garment causes it to stretch out of shape as the weight of the water pulls the fabric down. Lay it flat on a clean towel or a drying rack, gently reshape it to its original dimensions, and allow it to air dry completely before wearing or storing.

Store your skirt folded rather than hanging, again to prevent stretching.

Styling Your Ripple Swim Skirt

The Ripple Swim Skirt is endlessly versatile as a styling piece. Here are some ideas for wearing it beyond the obvious “thrown over a bikini at the beach” scenario.

At the beach or pool, pair it with a matching or complementary swimsuit top. Add a wide-brimmed sun hat, a pair of oversized sunglasses, and some sandals, and you have a complete resort-worthy look that took less effort than it appears.

For a casual summer afternoon, try wearing the skirt with a fitted tank top or crop top tucked in. A crochet skirt has enough visual texture on its own that it doesn’t need to compete with a complicated top, so keeping the upper half simple lets the skirt shine.

Going from the beach to a casual lunch or afternoon shopping? Swap your swimsuit top for a linen button-down shirt tied at the waist. The ripple skirt transitions surprisingly well from beach-mode to casual-chic.

A pair of leather sandals or espadrilles instantly elevates the skirt from purely beachwear to a genuine summer outfit. Add a woven tote bag and some simple jewelry and you’ve got a look that works for a farmers market, a rooftop happy hour, or a stroll through a beach town.
