What Is a Butterfly Top?

Before diving into the pattern, it helps to understand what makes a butterfly top a butterfly top. The name comes from the overall shape of the garment when it is laid flat. The body panels spread out symmetrically from the center, resembling a butterfly with open wings. When worn, the top typically features a relaxed, draped fit with open sides or tie details, a shallow neckline, and a hemline that hits somewhere between the waist and the hip.

The crochet version of this top became incredibly popular on social media over the past few years, and for good reason. The open stitchwork makes it breathable and lightweight, perfect for warm weather. It works beautifully as a swimsuit coverup, a beach layer over a bandeau or bikini top, or even styled with high-waisted jeans and a simple bralette underneath for an everyday boho look. The versatility is part of what makes this pattern so beloved in the crochet community.

Materials You Will Need

Getting your materials together before you start crocheting saves a lot of time and frustration. Here is what you will need to complete this project:

Yarn: For the classic butterfly top look, you want a lightweight yarn. A size 3 light DK or a size 10 crochet thread works beautifully for that delicate, airy appearance. Cotton yarn is the most popular choice because it is breathable, holds its shape well, and washes easily. Brands like Lion Brand 24/7 Cotton, Paintbox Cotton DK, or Scheepjes Catona are all excellent options. For a looser, more bohemian drape, you can also use a size 4 medium worsted weight cotton, though the finished top will be slightly heavier and less sheer.

You will need approximately 400 to 600 yards of yarn depending on the size you are making. Always pick up an extra skein to be safe — running out of yarn mid-project is every crocheter’s nightmare.

Hook: Match your hook to your yarn weight. For size 3 light yarn, a 3.5mm or 4mm hook works well. For worsted weight cotton, a 5mm hook is standard. Ergonomic hooks are worth the investment if you plan to crochet for long sessions — your hands will thank you.

Notions: You will also need a yarn needle for weaving in ends, scissors, stitch markers to keep your place, and a measuring tape. If your top has tie closures (as this pattern does), you may want an extra length of yarn or ribbon for the ties.

Gauge: Gauge matters for wearable garments. For this pattern using size 3 cotton yarn and a 4mm hook, aim for approximately 16 stitches and 10 rows per 4 inches in half double crochet. Always make a gauge swatch before starting. Blocking your swatch before measuring gives you the most accurate reading.

Sizing Guide

This pattern is written for sizes XS through XL, with notes for adjusting beyond that. Because the butterfly top is inherently a relaxed, draped design, exact sizing is more forgiving than it would be for a structured fitted top. The key measurement to focus on is your bust circumference.

XS fits a 30–32 inch bust, S fits a 33–35 inch bust, M fits a 36–38 inch bust, L fits a 39–41 inch bust, and XL fits a 42–44 inch bust. For sizes above XL, add one full pattern repeat for every two additional inches of bust measurement.

The finished top is designed with approximately 4–6 inches of positive ease, meaning it will be looser than your actual measurement. This is intentional. The drape and flow are part of the design.

Stitches and Abbreviations Used

This pattern uses standard US crochet terminology. Here are the stitches you will encounter:

ch — chain. sl st — slip stitch. sc — single crochet. hdc — half double crochet. dc — double crochet. ch-sp — chain space. sk — skip. rep — repeat. RS — right side. WS — wrong side.

If you are comfortable with basic crochet stitches, you already know everything you need for this pattern. There are no complicated techniques — just clean, well-placed stitches that build into a beautiful fabric.

The Pattern: Step-by-Step Instructions

Starting Chain and Foundation

Begin by creating a foundation chain. The butterfly top is worked in two identical panels that are later joined. This method makes it easy to adjust sizing and ensures symmetry.

For size M, chain 61. (For XS, chain 49. For S, chain 55. For L, chain 67. For XL, chain 73. Each chain adds approximately one inch of width per 6 chains.)

Row 1 (RS): Starting in the 3rd chain from your hook, hdc across. (59 hdc for size M.) Chain 2, turn.

Row 2: Hdc in each stitch across. Chain 2, turn.

Work rows 1 and 2 for a total of 8 rows. This creates the straight bottom band of the panel, which will sit at your waist or hip depending on how you wear the top.

Creating the Lace Body

Now comes the beautiful open lacework section that gives the butterfly top its signature look.

Row 9: Ch 4, sk 2 sts, dc in next st, (ch 1, sk 1, dc in next st) across to last 2 sts, dc in last 2 sts. Chain 3, turn.

Row 10: Sk first dc, dc in ch-1 sp, (ch 1, dc in next ch-1 sp) across, dc in last dc, dc in top of turning chain. Chain 4, turn.

Row 11: Sk first dc, dc in next dc, (ch 1, dc in next dc) across, ending with dc in top of turning chain. Chain 3, turn.

Repeat rows 10 and 11 until your panel measures approximately 12 inches from the foundation chain for a cropped length, or 14–15 inches for a slightly longer version. The lacework grows quickly and has a satisfying rhythm once you find your pace.

Shaping the Neckline

At this point your panel is a simple rectangle. To create the butterfly shape, you will work a gentle curve at the top center of each panel.

Mark the center of your panel with a stitch marker. You will be decreasing on either side of center over the next several rows to create a soft, rounded neckline dip.

Decrease Row 1: Work in pattern to 3 stitches before the center marker, hdc2tog, hdc in center, hdc2tog, work in pattern to end. Chain 2, turn.

Decrease Row 2: Work in pattern to 2 stitches before the center marker, hdc2tog, hdc2tog, work in pattern to end. Chain 2, turn.

Repeat Decrease Row 2 two more times total. You now have the gentle neckline curve. Continue working straight in pattern for 4 more rows without decreasing. This creates the shoulder section of the panel.

Do not fasten off yet.

Working the Shoulder Straps

For each panel, you will create two simple ties that function as shoulder straps and also tie at the waist or sides to close the top.

At the top outside corner of your panel: attach yarn, chain 50 (or longer for extra tie length), sl st back along the chain to create a firm cord. Fasten off and weave in end.

Repeat for all four corners of both panels — two at the top outside corners (these become shoulder ties), and two at the bottom outside corners (these become waist ties).

Making the Second Panel

Repeat the entire pattern from the foundation chain through the shoulder straps to create your second panel. Be sure it mirrors the first panel. If your first panel has the RS facing you when you read left to right, your second panel should be a mirror image.

Assembling the Top

Lay both panels flat on a table with the right sides facing up. The two panels will overlap slightly at the center to form the butterfly shape.

Place the panels side by side, overlapping at center by about 2–3 inches. Using a yarn needle and matching yarn, whipstitch or use a slip stitch join along the center overlap section. This join creates the front and back of the top simultaneously — the beauty of the butterfly design is that both sides look identical.

Alternatively, if you prefer a completely open-sided top, simply skip joining the panels and rely entirely on the ties to hold everything together. This version is stunning as a bikini coverup.

Weave in all remaining ends thoroughly. With cotton yarn especially, ends have a tendency to work themselves loose with wear, so take extra care here.

Blocking Your Finished Top

Blocking is the step that takes a handmade crochet garment from looking homemade to looking professionally crafted. Do not skip it.

Fill a basin with cool water and a small amount of gentle soap or wool wash. Submerge your finished top and gently squeeze the water through the fabric — do not twist or wring. Drain the soapy water and rinse thoroughly with cool water until the water runs clear.

Lay the top flat on a blocking mat or clean towels. Use rust-proof pins to gently stretch the lacework open and shape the panels into smooth rectangles. The butterfly shape should be clear and symmetrical when pinned out. Allow it to dry completely, which may take 12–24 hours depending on your environment.

Once dry and unpinned, the difference will be remarkable. The lace opens up beautifully, the fabric relaxes into an elegant drape, and the finished top looks far more polished than it did coming off the hook.

Customization Ideas

One of the most exciting things about this free crochet butterfly top pattern is how easy it is to make it your own.

Color: This pattern shines in a single solid color, but it also looks gorgeous in a slow color shift. Try a gradient yarn like Hobbii Rainbow Cotton or create your own gradient by fading between two or three coordinating colors. Changing colors every few rows in the lace section creates a subtle stripe effect that is lovely.

Yarn Substitution: Cotton is the standard choice, but bamboo yarn gives the top a silkier, more luxurious drape. Linen yarn is earthy and beautiful for a natural aesthetic. Even a fine mohair or a cotton-silk blend can work beautifully for an elevated evening look, though the finished top will be warmer.

Length: Add or subtract rows in the lace body section to adjust the length. A shorter version that sits right at the ribcage is perfect for pairing with high-waisted bottoms. A longer version that grazes the hip works well as a standalone top with fuller trousers or a maxi skirt.

Embellishments: Shell stitch edging along the bottom hem adds a sweet, feminine touch. A simple sc border around the entire outer edge of each panel cleans up the look. You can also thread ribbon through the lace section to add color and reduce sheerness, which makes the top more versatile for everyday wear.

Tie Styles: Instead of crocheted chains for the ties, try using a wide satin ribbon threaded through the corner stitches for a more polished finish. Leather cord or macramé cord also works for a more boho, festival-ready aesthetic.

Tips for Success

Tension consistency is the single most important factor in getting a beautiful result with this pattern. Try to crochet with the same tension throughout — not too tight, not too loose. If you notice your tension changing as you tire or if you crochet tighter when you are stressed, take breaks and check your work frequently.

Count your stitches at the end of every row, especially through the lace section. It is very easy to accidentally work into the wrong space and add or drop a stitch without noticing. Catching mistakes early saves a lot of frogging (unraveling) later.

Use stitch markers liberally. Mark the beginning of each row, the center point of your panel, and any decrease points. Markers are cheap and they save you enormous amounts of time and frustration.

If you are new to garment construction, making a test panel in inexpensive yarn before starting in your main yarn is always a good idea. This lets you practice the stitch pattern, check your gauge, and work through any confusion before committing your good materials.

Finally, trust the process. The panels look deceptively simple when laid flat, and it can be hard to visualize the finished top until the moment you tie it on. Many crocheters find themselves second-guessing the shape mid-project — keep going. The butterfly shape reveals itself beautifully once both panels are joined and the top is on your body.

Caring for Your Crochet Butterfly Top

To keep your finished top looking its best, hand wash it in cool water with a gentle soap each time you wear it. Lay flat to dry rather than hanging, which can stretch the fabric over time. Store it folded rather than hung in your closet for the same reason.

Cotton does get softer with each wash, so your top will actually become more comfortable with wear. Treat it gently and it will last for many summers.

Final Thoughts
