Crochet Sundress Free Pattern: Your Complete Guide to a Breezy Summer Staple

There is something undeniably satisfying about wearing something you made with your own hands, especially when that something is as effortlessly chic as a crochet sundress. Whether you are a seasoned crocheter looking for your next project or an adventurous beginner ready to level up, this free crochet sundress pattern is designed to walk you through every step of the process. By the end, you will have a beautiful, wearable garment that looks like it came straight from a boutique — and cost you a fraction of the price.

This pattern is worked from the top down, meaning you start with the bodice and work your way to the hem. This approach makes sizing and fitting far more intuitive, because you can try the dress on as you go and adjust the length to suit your preference. The design features a simple but striking lace-like stitch pattern in the skirt, a fitted bodice with adjustable straps, and a silhouette that flatters a wide range of body types.

So grab your hook, pour yourself a cold drink, and let’s get started.

Materials You Will Need

Before diving into the pattern itself, let’s talk about what you will need to pull this project together. Having everything on hand before you begin will make the process much smoother.

Yarn: Approximately 800 to 1,200 yards of DK weight or light worsted yarn, depending on your size. For a sundress, you want something breathable and lightweight. Cotton yarn is the gold standard for warm-weather garments because it drapes beautifully, holds its shape, and doesn’t trap heat. Some excellent choices include Lion Brand 24/7 Cotton, Paintbox Yarns Simply DK, or Paintbox Yarns Cotton DK. If you want a little more drape and sheen, a cotton-linen blend is a gorgeous option.

Hook: A US size G/6 (4.0 mm) crochet hook. If your gauge is off, you may need to go up or down half a size.

Notions: A yarn needle for weaving in ends, scissors, stitch markers (at least 4), a measuring tape, and approximately 1.5 to 2 yards of ribbon, thin elastic, or adjustable straps if you prefer added support.

Optional: A row counter, blocking mats and pins for finishing, and a dress form or mannequin if you have one.

Gauge

Getting gauge right is the single most important step in any garment project, and yet it is also the step most crocheters are tempted to skip. Please don’t skip it. A small difference in gauge multiplied across hundreds of stitches adds up quickly and can mean the difference between a dress that fits perfectly and one that doesn’t fit at all.

Gauge: 16 stitches and 18 rows = 4 inches (10 cm) in single crochet using a G/6 hook and your chosen yarn.

To check your gauge, crochet a swatch of at least 20 stitches and 20 rows. Fasten off, weave in your ends, and block the swatch before measuring. If your swatch is too large, try a smaller hook. If it is too small, go up a hook size.

Sizing Guide

This pattern is written to accommodate a range of sizes. The measurements below refer to your actual bust measurement, not the finished garment measurement, which includes ease.

Small: 32–34 inches bust
Medium: 35–37 inches bust
Large: 38–40 inches bust
Extra Large: 41–43 inches bust
2X: 44–46 inches bust

Throughout the pattern, stitch counts for each size are listed in parentheses in this order: (S, M, L, XL, 2X). If only one number is given, it applies to all sizes.

The finished dress as written falls roughly to mid-calf on a 5’5″ figure. You can easily make it shorter or longer by adjusting the number of skirt repeats, which will be explained in the skirt section.

Part One: The Bodice

The bodice is worked flat in two panels — a front and a back — which are then joined at the sides. This construction allows you to shape the neckline and armholes independently, giving a cleaner and more tailored finish than working in the round would allow.

Front Bodice Panel

Begin by chaining (66, 70, 76, 82, 88).

Row 1 (RS): Sc in the 2nd ch from hook and in each ch across. Turn. You should have (65, 69, 75, 81, 87) sts.

Rows 2–4: Ch 1, sc in each st across. Turn.

Row 5: Ch 1, sc2tog, sc in each st across to last 2 sts, sc2tog. Turn. (63, 67, 73, 79, 85) sts remain.

Rows 6–8: Ch 1, sc in each st across. Turn.

Repeat Rows 5–8 twice more. You should now have (59, 63, 69, 75, 81) sts.

Continue working even in sc (no shaping) until the bodice panel measures 5 (5.5, 6, 6, 6.5) inches from the foundation chain, ending on a WS row.

Armhole Shaping

Row 1: Sl st across the first (8, 8, 9, 9, 10) sts, ch 1, sc in the same st as last sl st and in each st across to last (8, 8, 9, 9, 10) sts. Leave remaining sts unworked. Turn. You should have (43, 47, 51, 57, 61) sts.

Row 2: Ch 1, sc2tog, sc in each st across to last 2 sts, sc2tog. Turn.

Rows 3–6: Repeat Row 2. You should have (33, 37, 41, 47, 51) sts after Row 6.

Continue even until the bodice (measured from the armhole bind-off row) is (6, 6.5, 6.5, 7, 7) inches tall.

Neckline Shaping

With RS facing, sc across the first (9, 11, 12, 14, 16) sts. Fasten off. Skip the center (15, 15, 17, 19, 19) sts and rejoin yarn at the next st. Sc across the remaining (9, 11, 12, 14, 16) sts. Fasten off. These form the two shoulder straps.

Back Bodice Panel

Work the back panel exactly as the front panel through the armhole shaping. When the back panel (measured from the armhole bind-off row) is (4, 4, 4.5, 4.5, 5) inches tall, begin the back neckline shaping in the same way as the front. The back neckline sits slightly lower than the front for comfort and ease of wearing.

Joining the Panels

Place the front and back panels with right sides together. Using a yarn needle and a length of yarn, seam the shoulder straps together using a whipstitch or mattress stitch. Then seam the side panels together from the armhole down to the bottom edge of the bodice. Turn right side out and try the bodice on to check the fit before proceeding to the skirt.

Part Two: The Skirt

The skirt is where this pattern really shines. It is worked in the round, directly attached to the lower edge of the bodice, and features a beautiful combination of shells and V-stitches that create an open, airy fabric perfect for warm weather. The skirt naturally flares outward as you work, creating a flattering A-line silhouette.

Attaching the Skirt

With RS facing, join yarn at one side seam on the lower edge of the bodice. You will work into the foundation chain of the bodice rather than into the stitches themselves, which gives a neater join.

Round 1: Ch 3 (counts as dc), work dc evenly around the bottom edge of the bodice, making sure your total stitch count is a multiple of 12 plus 2. Adjust with small increases or decreases as needed to hit your target count. Sl st to the top of the ch-3 to join. Your approximate stitch counts should be (74, 86, 98, 110, 122).

Round 2: Ch 4 (counts as dc plus ch 1), skip 1 st, dc in next st, ch 1, skip 1 st; rep from around. Sl st to 3rd ch of ch-4 to join. This sets up the foundation for the shell pattern.

Shell and V-Stitch Pattern (worked in the round)

Round 1: Sl st into the first ch-1 sp, ch 3 (counts as dc), 2 dc in same sp (half shell made), ch 1, sk next ch-1 sp, V-st in next ch-1 sp, ch 1, sk next ch-1 sp, shell in next ch-1 sp; rep from around, ending with ch 1, sk next ch-1 sp, V-st in next ch-1 sp, ch 1, sl st to top of ch-3 to join.

Round 2: Sl st to center dc of first half shell, ch 3, 2 dc in same st (continuing half shell), ch 1, shell in ch-2 sp of next V-st, ch 1, V-st in center dc of next shell; rep from around, ending ch 1, shell in ch-2 sp of last V-st, ch 1, sl st to top of ch-3. Note that the half shells and shells alternate with V-stitches on this round.

Round 3: Sl st to center dc of first shell, ch 5 (counts as dc plus ch 2), dc in same st (V-st made), ch 1, V-st in center dc of next shell, ch 1, shell in ch-2 sp of next V-st; rep from around, ending ch 1, sl st to 3rd ch of ch-5.

Repeat Rounds 2 and 3 alternately, working your way down the skirt.

Adding Width as You Go

Because we want the skirt to flare naturally, you will work an increase round every 6 rounds. On an increase round, instead of working a standard V-stitch in the shell center, work (dc, ch 2, dc, ch 2, dc) — essentially a double V-stitch — which adds two extra stitches and opens the fabric slightly more. This keeps the shell pattern intact while allowing the skirt to grow outward gradually without any awkward bunching.

Continue working the shell pattern with increase rounds until the skirt reaches your desired length. As a general guide, approximately 20 to 24 pattern rounds will bring the skirt to mid-calf on a 5’5″ figure. Fewer rounds will give you a cute mini or midi length; more rounds will take you toward a maxi dress.

Finishing the Hem

On the final round of the skirt, work the following:

Final Round: Sl st into first ch-1 sp, ch 1, sc in same sp, ch 3, sc in next sp; rep from around, sl st to first sc. Fasten off. This creates a simple picot-style edge that frames the hem without adding bulk.

Part Three: Finishing Touches

Strap Options

The straps can be finished in several ways depending on your preference and how much support you need.

For a simple crocheted strap, pick up stitches across the shoulder strap area and work 4 rows of sc, then fold over and slip stitch to the inside for a neat finished edge. Add a button and buttonhole if you like an adjustable option.

For thin ribbon straps, weave a length of grosgrain ribbon or satin ribbon through the shoulder openings and tie at the desired length. This gives a soft, feminine look and is easy to adjust.

For built-in support, sew a length of braided elastic to the inside edge of the bodice, stretching it slightly as you go to create a gentle gathered effect. This works especially well for larger sizes.

Neckline and Armhole Edging

With RS facing, join yarn at one shoulder seam. Work a round of sc evenly around the neckline, then sl st to join. Work one more round of reverse sc (also called crab stitch) for a polished edge that won’t curl. Repeat for each armhole.

Blocking

Blocking is the finishing step that transforms a crochet garment from homemade to handcrafted. Soak your finished dress in cool water for 15 to 20 minutes, gently squeeze out the excess water (do not wring), and lay flat on blocking mats. Pin the dress into shape, gently stretching the skirt to open up the shell and V-stitch pattern. Allow to dry completely — this may take 24 hours depending on your yarn and the humidity in your space.

Once blocked, the lace pattern in the skirt will open beautifully and the entire dress will drape with much more elegance than it did off the hook.

Styling Your Crochet Sundress

Once your dress is finished and blocked, the fun really begins. A crochet sundress is one of the most versatile pieces in a summer wardrobe. Here are a few ways to style it.

Wear it over a slip dress or fitted tank and shorts for a layered boho look that keeps the crochet fabric as a decorative outer layer while ensuring full coverage underneath. Pair with strappy sandals and a wide-brim hat for an effortless beach or festival outfit. Dress it up with block-heeled mules and simple gold jewelry for a summer evening out. Throw a denim jacket over the top as the evenings cool down and the look instantly becomes more relaxed and casual.

Because the yarn is cotton, you can also toss the dress in a gentle machine wash cycle (cold water, delicate setting) for easy care. Lay flat to dry rather than using the dryer to maintain the shape and keep the fibers from shrinking.

Tips for Success

A few notes that will make your experience with this pattern much smoother. Always join new yarn at a side seam rather than mid-row so any color joins or ends are hidden in a less visible spot. Use stitch markers generously — especially in the skirt — to keep track of where your pattern repeats begin and end. If the pattern ever starts to look off, count your stitches before continuing rather than assuming it will work itself out after a few more rows.

If you are new to garment construction, don’t be intimidated by the shaping sections. Read through the entire pattern once before you begin, so nothing catches you off guard. Worked one row at a time, even the most complex garment becomes manageable.

Finally, trust the process. Crochet fabric looks different on the hook than it does blocked and worn. What seems stiff or small mid-project will almost always open up and soften into something beautiful with blocking and wear.

Share Your Makes

If you use this free crochet sundress pattern, I would love to see what you create. Share your finished project with the hashtag #CrochetSundress so others in the community can find inspiration from your work. There is no single way to make this pattern your own — swap in a different stitch for the skirt, change the neckline shape, add pockets (pockets!), or work it in a bold color that makes you happy every time you wear it.

Crochet is at its best when it is shared, and a handmade garment tells a story that no store-bought item ever quite can. Every stitch is a small act of creativity, patience, and care — and wearing the finished result is one of the most rewarding feelings in the world.

Happy crocheting.
