Easy Swimsuit Cover Up Free Crochet Pattern

There is something undeniably satisfying about walking to the beach or pool wearing something you made yourself. A handmade crochet swimsuit cover up carries that effortless, boho energy that store-bought versions try so hard to replicate but never quite manage. And the best part? You do not need to be an advanced crocheter to make one. This easy swimsuit cover up free crochet pattern is designed for anyone who knows their basic stitches and wants a quick, rewarding project that actually gets worn.

Whether you are making this for yourself, a friend, or a daughter heading off to summer camp, this pattern from Jenny and Teddy will walk you through every step. It works up faster than you expect, uses affordable yarn, and can be customized to fit almost any body shape or size. Let us get into everything you need to know before you pick up your hook.

Why Crochet Your Own Swimsuit Cover Up?

Before we dive into the pattern itself, it is worth talking about why making your own cover up is such a fantastic idea. If you have ever browsed swimwear sections in retail stores or scrolled through boutique websites, you already know that cover ups can be surprisingly expensive for what they are. A simple mesh cover up that takes maybe a few hundred yards of yarn to make can retail for forty, sixty, or even over a hundred dollars depending on the brand.

When you crochet your own, the cost drops dramatically. Most cover ups at this size require only one or two skeins of lightweight cotton yarn, which puts your total material cost well under twenty dollars in most cases. You also get to choose exactly the color, length, and drape you want, which means no more settling for whatever happens to be in stock.

Beyond the practical benefits, there is the creative satisfaction. Every stitch is yours. When someone compliments your cover up at the beach and you say, “I made it,” there is a particular kind of joy that comes with that moment. Crochet has a wonderful way of turning ordinary afternoons into something productive and meditative, and a project like this one gives you a tangible reward for that time.

Materials You Will Need

Getting your materials together before you start saves you from stopping mid-project to run to the craft store. Here is everything you will need for this easy swimsuit cover up free crochet pattern.

Yarn: You will want a lightweight, breathable yarn for this project. Cotton or a cotton blend works beautifully because it holds up in humid beach environments, washes easily, and has a lovely drape that makes crochet cover ups look intentional rather than bulky. Look for a yarn labeled DK weight or light worsted weight. One popular and affordable choice is Lion Brand 24/7 Cotton in any color you love. Neutral tones like sand, white, and natural are classic, but a pop of coral or sky blue is equally gorgeous. Plan on approximately 400 to 600 yards depending on your size.

Hook: A 5.0 mm or 5.5 mm crochet hook is the sweet spot for this weight of yarn and this style of project. The slightly larger hook than you might expect creates a more open, lacy fabric that lets the swimsuit peek through and gives the cover up that airy feel you want.

Notions: You will need a yarn needle for weaving in ends, scissors, and stitch markers to keep your place. A measuring tape is helpful for checking your dimensions as you go. Optional but lovely: a few wooden beads or shell charms you can thread onto yarn for decorative fringe at the hem.

Gauge and Sizing

For this pattern, gauge is somewhat forgiving because of the open mesh structure, but it is still worth doing a quick gauge swatch before committing to the full project. You are aiming for approximately 14 stitches and 8 rows equaling 4 inches in the main stitch pattern described below.

This pattern is written for a small to medium adult size, with notes throughout on how to adjust for larger sizes. The finished garment is designed to hit at mid-thigh and has a relaxed, oversized silhouette. If you want a longer maxi-style cover up, simply add extra rows to the body section. If you want a shorter beach top style, subtract rows. The beauty of this design is that it is entirely adjustable.

Understanding the Main Stitch Pattern

This cover up uses what is sometimes called a simple mesh or lattice stitch, which creates the open, net-like fabric that makes crochet cover ups so appealing. If you have ever done a basic chain and double crochet combination, you already know how to do this stitch. It is beginner-friendly but looks impressively intricate once you are holding the finished piece.

The mesh pattern works like this: you alternate chain spaces with double crochets in a rhythm that creates a diagonal grid effect. It is rhythmic enough that you can get into a meditative groove quickly, but it has just enough structure that you are always sure where to place your next stitch. Once you crochet the first two or three rows, your hands will know the pattern without you having to think about it.

The Pattern

Abbreviations used:
ch = chain, dc = double crochet, ch-sp = chain space, sk = skip, sl st = slip stitch, sp = space, st = stitch

Foundation:
Chain 101. This gives you a foundation chain that measures approximately 28 inches before any stretch, which is the right starting point for a cover up that wraps comfortably around most body sizes. If you want to size up, add chains in multiples of 4.

Row 1:
Dc in the 5th chain from the hook (the skipped chains count as dc plus ch-2), ch 2, skip 2 chains, dc in the next chain. Repeat the “ch 2, skip 2, dc” sequence all the way across to the end of your foundation chain. Turn your work.

Row 2:
Ch 4 (counts as dc plus ch-2 here and throughout), turn. Dc in the first ch-2 space, ch 2. Continue working one dc into each ch-2 space across the row with a ch-2 between each dc. When you reach the last space, dc in the 3rd chain of the turning chain from the previous row. Turn.

Rows 3 and onward:
Repeat Row 2 until your piece measures the length you want. For the mid-thigh length described in this pattern, continue until the piece measures approximately 22 to 24 inches from the foundation chain to your working edge. This will take you roughly 44 to 48 rows depending on your tension.

At this point, do not fasten off. You are going to join the sides to create the tube shape of the cover up.

Joining the Sides and Creating Armholes

Fold your crocheted rectangle so that the two short edges meet. You will join these edges together using a slip stitch seam, but you will leave openings for the armholes.

Starting from the bottom hem, slip stitch the two edges together through corresponding stitches or row ends for approximately 8 inches upward. This creates the lower portion of the side seam.

Then leave approximately 7 to 8 inches open for the armhole. If you are making a larger size, you may want to leave up to 9 or even 10 inches open so the armhole is comfortable.

After the armhole gap, slip stitch the remaining seam closed up to the top edge of the cover up, leaving about 5 to 6 inches open at the top for the neckline and shoulder area.

Repeat the same process on the opposite side. When you are finished joining both sides, you will have a garment that slips over the head, with armholes on each side and a wide, open neckline.

Finishing the Neckline and Armhole Edges

The raw edges of crochet can look untidy if left as-is, so it is worth taking an extra thirty minutes to edge the neckline, armhole openings, and hem with a simple border. This also gives the cover up a polished look that makes it appear far more professional.

For the neckline:
Join your yarn at any point along the neckline opening. Work one round of single crochets evenly around the entire opening, placing stitches into each stitch and each row end as needed to maintain a flat, even edge. When you return to where you started, slip stitch to join. Fasten off and weave in the end.

For the armholes:
Join your yarn at the bottom of one armhole opening and work one round of single crochets around the entire armhole. Join with a slip stitch. Repeat on the other armhole. These small borders not only look neat but also prevent the armhole edges from stretching out of shape over time.

For the hem:
If you want to add a decorative touch at the hem, this is the moment to do it. One beautiful option is a simple shell border: join yarn at any point along the hem, single crochet into the first stitch, skip 2 stitches, work 5 double crochets into the next stitch for the shell, skip 2 stitches, single crochet into the next stitch, and repeat this sequence all the way around. The result is a scalloped, feminine hem that makes the cover up look custom-made.

Adding Fringe (Optional but Gorgeous)

If you want to lean into the bohemian beach aesthetic, adding fringe along the hem is one of the quickest ways to elevate this cover up from simple to stunning. Cut lengths of yarn approximately 12 inches long. Fold each length in half, insert the folded end through a stitch at the hem, pull the loose ends through the loop, and tighten gently. Space your fringe every other stitch for a full, lush look, or every few stitches for something more sparse and minimal.

You can also add small shell or bead embellishments by threading them onto individual strands of fringe before trimming the ends to a uniform length.

Tips for Getting the Best Results

A few practical notes that will make this project go more smoothly from start to finish.

Blocking your finished cover up makes a significant difference in how it looks and drapes. Wet blocking cotton is easy: simply soak the finished piece in cool water for about fifteen minutes, gently squeeze out excess water without wringing, and lay it flat on a clean towel in the shape and dimensions you want. Allow it to dry completely before wearing. This evens out any tension inconsistencies and gives the mesh a beautiful, open quality.

Pay attention to your tension as you work. The most common issue with open mesh crochet is tension that tightens over the course of the project, resulting in a trapezoid shape rather than a rectangle. Periodically lay your work flat and measure both the top edge and the current working edge to make sure they are remaining consistent.

If you are crocheting for a longer body length or a plus size, remember to account for additional yarn when shopping. It is always better to purchase an extra skein at the start than to find out mid-project that your dye lot is no longer available.

Customizing This Pattern

One of the things that makes this easy swimsuit cover up free crochet pattern so versatile is how readily it lends itself to customization. Here are a few ideas to make it your own.

You can create a color-blocked effect by switching yarn colors every six to eight rows and weaving in your ends as you go. Even two colors in the same tonal family create a subtle, sophisticated stripe effect that looks very intentional.

For a sarong-style cover up instead of a pullover, simply skip the joining step entirely. Leave your rectangle flat, add fringe or a shell border to all four edges, and use it as a wrap that ties at the waist or hip. This is also a great option if you want to make the project even faster.

For a cover up dress, start with a longer foundation chain and work more rows so the finished piece reaches below the knee. Add thin crochet straps at the top edge rather than leaving armholes, and you have a completely different garment that works equally well at the beach and at a casual summer dinner.

Caring for Your Crochet Cover Up

Cotton crochet is wonderfully easy to care for compared to wool or acrylic. Machine wash on a gentle or delicate cycle with cold water and a mild detergent. Lay flat to dry whenever possible, as tumble drying can cause the mesh to shrink slightly over many cycles. Your cover up will soften and become even more drapey with each wash, which is one of the things crochet enthusiasts love about cotton.

Store it rolled loosely rather than folded when possible. Because mesh crochet has an inherent elasticity, folding in the same crease over and over can create permanent lines in the fabric, whereas rolling keeps the fabric relaxed and shapely.

Final Thoughts

This easy swimsuit cover up free crochet pattern is exactly the kind of project that reminds you why you fell in love with crochet in the first place. It is approachable enough for a beginner who knows their basic stitches, fast enough to finish in a weekend or two of casual crocheting, and beautiful enough to wear with real pride. The mesh stitch is satisfying to work, the construction is intuitive once you understand the basic structure, and the finished result is something you will reach for every time summer comes around.

If you make this cover up, we would love to see it. Share your finished project and tag Jenny and Teddy so we can celebrate your work. Happy crocheting, and here is to a summer full of sunny days, warm water, and beautiful handmade things.
