Why Crochet a Boho Sundress?

Boho fashion and crochet have always been natural partners. The organic texture of handmade stitches pairs beautifully with the free-spirited aesthetic of bohemian style, and the open lacework that crochet creates so naturally is perfectly suited for warm-weather dressing. Unlike knitting, crochet tends to build fabric more quickly and gives you greater control over drape and density, making it ideal for garments like sundresses that need to move beautifully with the body.

A crochet sundress also offers something store-bought clothing simply cannot: a perfect fit. You are not hunting through racks hoping something comes close. You are building the dress to your measurements from the very first stitch, adjusting the length, width, and neckline exactly as you like. And with the boho style lending itself to relaxed silhouettes, there is a wonderful amount of creative freedom in this kind of project.

Materials You Will Need

Before diving into the pattern itself, gather your supplies. Having everything ready before you begin makes the process smoother and more enjoyable.

Yarn: For a truly wearable summer sundress, fiber choice is everything. You want something breathable, soft against the skin, and with enough drape to flow rather than stiffen. Cotton yarn is the classic choice and works beautifully here. Look for a lightweight or DK weight cotton or cotton-blend yarn. Some wonderful options include 100% mercerized cotton for a slight sheen, linen-cotton blends for extra drape and structure, or bamboo-blend yarns for an incredibly silky feel.

For a finished dress that hits mid-thigh to knee length in a size medium, plan on approximately 1,200 to 1,600 yards of yarn. If you are making a maxi version, add another 600 to 800 yards depending on your height. Always buy one extra skein. Running out of yarn mid-project is one of the most frustrating experiences in fiber arts, and having a backup skein means you can also use it for fringe, straps, or embellishment.

Hook: A 4.0 mm or 4.5 mm crochet hook works beautifully with DK weight cotton. The slightly larger hook opens up the lace stitches and gives the finished fabric that gorgeous airy quality essential to the boho aesthetic. Ergonomic hooks with cushioned grips are worth every penny if you plan to crochet for extended sessions.

Additional supplies: You will also need a tapestry needle for weaving in ends, stitch markers (at least six), a flexible measuring tape, scissors, and blocking mats with pins if you want to block the finished dress for an extra-polished result. Optional but lovely: a few small wooden or shell buttons if you want to add closure detail to the bodice, and a length of ribbon or crochet cord for a waistband tie.

Gauge and Sizing

Gauge: 16 stitches and 10 rows = 4 inches in the main stitch pattern using a 4.0 mm hook. Always make a gauge swatch before beginning. It only takes about 20 minutes and saves hours of frustration. If your swatch is too small (more stitches per inch than listed), try a larger hook. If it is too large, go down a hook size.

This pattern is written for sizes XS through 2XL with finished bust measurements ranging from 32 inches to 52 inches. The dress is designed with 2 to 4 inches of ease for a relaxed, flowing fit.

Sizes at a glance:

• XS: 32–34 inch bust, chain 120 to start
• S: 36–38 inch bust, chain 135 to start
• M: 38–40 inch bust, chain 150 to start
• L: 42–44 inch bust, chain 165 to start
• XL: 46–48 inch bust, chain 180 to start
• 2XL: 50–52 inch bust, chain 195 to start

Throughout the pattern, instructions for larger sizes will appear in parentheses in the order XS (S, M, L, XL, 2XL).

Stitch Glossary

This pattern uses the following stitches. If any are unfamiliar, take a few minutes to practice them before starting the dress.

Chain (ch): The foundational stitch of crochet. Make a slip knot, then draw yarn through the loop on your hook.

Single crochet (sc): Insert hook into stitch, draw up a loop, yarn over, pull through both loops.

Half double crochet (hdc): Yarn over, insert hook into stitch, draw up a loop (3 loops on hook), yarn over, pull through all three loops.

Double crochet (dc): Yarn over, insert hook into stitch, draw up a loop, yarn over and pull through two loops, yarn over and pull through remaining two loops.

Shell stitch: Work 5 double crochets into the same stitch or space. This creates the classic fan shape central to the boho lace bodice of this dress.

V-stitch: Work (dc, ch 2, dc) into the same stitch. Creates an open, airy texture perfect for warm weather fabric.

Picot: Ch 3, slip stitch into the first chain made. Creates a delicate decorative point, used here along the hem.

Magic ring: An adjustable loop used to begin working in the round without a hole at the center.

Construction Overview

This dress is constructed from the top down, which means you start at the neckline and work your way to the hem. This method has several advantages: you can try the dress on as you go, adjust the length whenever you like, and the hem remains open for easy customization. The bodice is worked in a combination of shell stitches and V-stitches to create a lacy, structured yoke that sits beautifully across the chest and shoulders. The skirt transitions into a more open, flowing ripple pattern that creates the characteristic boho movement when you walk.

The dress is worked flat (back and forth in rows) for the bodice, then joined to work in the round for the skirt portion, eliminating the need for side seams below the waist.

The Pattern

Part One: The Bodice

Foundation: Chain 120 (135, 150, 165, 180, 195). This will form the top edge of your dress, running from the back, over the shoulders, and across the front.

Row 1 (Wrong side): Starting in the 4th chain from the hook, work 1 dc in each chain across. Turn. You will have 117 (132, 147, 162, 177, 192) dc.

Row 2 (Right side): Ch 3, turn. Skip the first 2 stitches. Work a shell stitch (5 dc) into the next stitch. Skip 2 stitches. Work 1 sc into the next stitch. Skip 2 stitches, work a shell stitch into the next stitch, skip 2 stitches, work 1 sc into the next stitch. Repeat from across to the last 3 stitches. Skip 2 stitches, work 1 dc into the last stitch.

Row 3: Ch 1, turn. Work 1 sc into the first dc. Ch 2, work 1 dc into the center dc of the next shell. Ch 2, work 1 sc into the next sc. Repeat from across.

Row 4: Ch 3, turn. Work a shell stitch into the first sc. Work 1 sc into the next dc (the center of the chain-2 arch). Work a shell stitch into the next sc. Repeat from across, ending with 1 dc into the last sc.

Repeat Rows 3 and 4 until the bodice measures 7 (7.5, 8, 8.5, 9, 9.5) inches from the foundation chain, ending with a Row 3 repeat. Do not fasten off.

Armhole shaping: You will now divide the bodice for the front and back panels and shape the armholes by working each section separately.

Count the total number of shell stitches across the row. Set aside approximately one quarter for each back panel and reserve the center half for the front panel. Mark these sections with stitch markers.

Work Row 4 across the first back panel section only. Turn and work Row 3 back. Continue in pattern for 4 more rows. Fasten off. Rejoin yarn at the corresponding point for the second back panel and repeat. For the front panel, rejoin yarn and continue in pattern for 6 rows to create a slightly deeper armhole. Fasten off.

Seam the shoulder sections together using a tapestry needle and whip stitch, matching the shell patterns as closely as possible for a seamless look.

Part Two: The Waistband

The waistband provides definition and is where you will attach the skirt. It is worked in simple half double crochet rounds to create a firm, structured band that holds everything together.

Rejoin yarn at the bottom edge of the bodice at the side seam. Place a stitch marker here to track the beginning of your round.

Round 1: Work 1 hdc into each stitch and the end of each row evenly around the entire lower edge of the bodice. Join with a slip stitch to the first hdc.

Round 2: Ch 2 (counts as hdc). Work 1 hdc into each stitch around. Join with slip stitch.

Round 3: Work as Round 2.

At this point, if you want a ribbon or tie waistband, work a Row 4 of ch 2, skip 2 stitches, hdc, repeat around to create eyelets for threading your ribbon through.

Part Three: The Skirt

The skirt transitions from the structured waistband into a flowing ripple and V-stitch pattern that grows increasingly open toward the hem. This creates the beautiful layered, flowy quality that defines a great boho dress.

Round 1 (Increase Round): Ch 4 (counts as dc + ch 1). Skip 1 stitch. Work (dc, ch 2, dc) into the next stitch (V-stitch made). Skip 1 stitch. Work 1 dc into the next stitch. Ch 1. Skip 1 stitch. Repeat from around. Join with slip stitch into the 3rd chain of starting ch-4.

Round 2: Slip stitch into the first ch-1 space. Ch 3. Work 4 more dc into the same space (shell made). Work 1 sc into the next ch-2 space of the V-stitch. Work a shell stitch into the next ch-1 space. Repeat from around. Join.

Round 3: Ch 5. Work 1 dc into the center dc of the next shell. Ch 2. Work 1 sc into the next sc. Ch 2. Repeat from around. Join.

Round 4: Work as Round 2.

Continue repeating Rounds 3 and 4 until the skirt reaches your desired length, minus 2 inches for the hem border.

For a mini dress: approximately 12 to 14 inches of skirt length.
For a midi dress: approximately 22 to 26 inches.
For a maxi dress: approximately 36 to 40 inches depending on your height.

Part Four: The Hem Border

The hem is where the dress gets its finishing boho flair. A picot edging gives it that delicate, handmade beauty that elevates the whole piece.

Round 1: Work 1 sc into each stitch and space around the bottom edge of the skirt. Join.

Round 2: Work 1 sc into the next stitch. Work a picot (ch 3, slip stitch into the first chain). Work 1 sc into the next stitch. Skip 1 stitch. Repeat from around. Join and fasten off.

Weave in all ends carefully using your tapestry needle.

Part Five: The Straps

The straps are crocheted separately and attached to the bodice. You can make simple narrow straps, wider halter-style straps, or even an off-the-shoulder tie arrangement depending on your preference.

For simple adjustable straps:

Chain 80 (or longer for ties). Row 1: Work 1 sc in each chain across. Row 2: Ch 1, turn. Work 1 sc in each sc across. Fasten off, leaving a long tail for sewing.

Make two straps. Try on the dress (or use a dress form or measurements) and pin the straps in place at the desired position along the front and back bodice edges. Sew securely using the tapestry needle and yarn tail, going through several stitches in multiple directions for strength.

Finishing and Blocking

Once all pieces are assembled and ends are woven in, blocking will transform your dress. Blocking is the process of wetting or steaming the finished piece and pinning it into the correct dimensions to dry. For cotton and cotton-blend yarns, wet blocking works beautifully.

Submerge the finished dress in cool water and gently squeeze (never wring) out the excess. Lay it flat on your blocking mats, pinning the hem, straps, and bodice into shape. Smooth out the lace pattern with your fingers. Allow it to dry completely, which usually takes 24 hours. The difference in appearance before and after blocking is remarkable: stitches open up, the fabric softens, and the finished dimensions stabilize.

Styling Your Boho Crochet Sundress

Once you have your beautiful handmade dress in hand, the styling possibilities are endless. Wear it over a coordinating swimsuit at the beach with shell jewelry and woven sandals for a coastal boho look. Layer it over a slip dress or linen trousers for an elevated festival-ready ensemble. Add a wide-brimmed hat and woven tote bag for weekend farmers market trips. A denim jacket thrown over the shoulders takes it seamlessly from warm afternoons into cool summer evenings.

Consider making the dress in an unexpected color for maximum impact: dusty terracotta, sage green, warm cream, or even a gradient effect by changing yarn colors as you go through the skirt section.

Tips for Success

Work a full gauge swatch and take the time to wash it before measuring, because cotton can relax after its first wash. When joining for working in the round at the skirt section, take care that your work is not twisted. Mark the beginning of each round consistently so you never lose your place. If you want to add extra structure to the bodice, work an additional row or two of hdc at the top edge. And always, always try the dress on as you go — the beauty of top-down construction is that fitting is built right into the process.

Final Thoughts

A crochet sundress is more than a garment. It is a wearable record of your time, your patience, and your creativity. Every stitch is a small act of making, and the finished dress carries all of that energy with it. The boho aesthetic of this particular design means it will age gracefully with you — bohemian style has a timeless quality that never really goes out of fashion.

Whether you make this dress in a weekend marathon session or spread the work across a few weeks of evenings, the process is as rewarding as the result. Save this pattern, share it with a friend who crochets, and don’t be afraid to make it your own. Adjust the length, change the stitches, add fringe to the hem, or incorporate beads into the border. This pattern is a starting point, and where you take it from here is entirely up to you.

Happy crocheting, and enjoy every sunny day you spend wearing something you made with your own two hands.
