Let’s dive in.
Why You’ll Love This Pattern
Before we get into the specifics of yarn and hooks, it helps to understand what makes this particular dress design so worth your time and effort.
The Coastal Blue Bell Sleeve Crochet Dress is worked in three main sections: the bodice, the skirt, and the sleeves. Each section is designed to work harmoniously with the others, which means you do not need to struggle with complicated seaming or awkward joins. The bodice is worked flat and then seamed, giving you easy control over fit. The skirt is worked in the round from the waist down, incorporating increases to create the gentle flare that gives it that effortless boho silhouette. The bell sleeves are worked separately and attached at the armhole, and their gradual increases from the shoulder to the wrist cuff make them look far more complex than they actually are.
The stitch pattern used throughout the body is a simple combination of double crochet and chain spaces that creates an open, lace-like fabric — perfect for warm coastal weather. It drapes beautifully on the body and allows airflow while still providing enough coverage to feel polished and put-together.
Materials You’ll Need
Getting your materials together before you begin is one of the most satisfying parts of any crochet project. Here is everything you will need for the Coastal Blue Bell Sleeve Crochet Dress.
Yarn: You will need approximately 1,200 to 1,500 yards of a DK weight or light worsted yarn depending on your size. Look for a yarn that has some drape to it — cotton blends, bamboo cotton, and linen blends all work beautifully for garments like this. For the coastal color palette, consider shades like dusty teal, ocean blue, seafoam, pale aqua, or even a soft sandy ecru if you prefer a neutral tone. The coastal blue color referenced in this pattern’s name works beautifully as a solid, but a tonal or lightly variegated yarn in ocean hues can add an extra layer of visual interest.
Hook: A 4.0mm or 4.5mm crochet hook is recommended. Check your gauge before beginning, as the hook size that works best for your tension may differ slightly from the recommendation. Always swatch first for garments — it makes all the difference between a dress that fits perfectly and one that needs significant adjustment.
Notions: You will also need a yarn needle for weaving in ends and seaming, stitch markers, scissors, and a measuring tape. A few locking stitch markers are especially helpful for marking the armhole placements and the beginning of rounds.
Optional: A crochet blocking mat and pins are highly recommended for finishing. Blocking a crochet garment transforms it from handmade to heirloom, evening out the stitches and helping the fabric drape beautifully.
Gauge and Sizing
Gauge: 14 double crochets and 8 rows = 4 inches (10 cm) in the main stitch pattern using a 4.0mm hook. Always make a gauge swatch at least 5 inches square, wash and dry it as you intend to care for the finished dress, and measure it before proceeding. Yarn and individual tension vary, and a correct gauge is especially important in garments.
Sizes: This pattern is written for sizes XS through 2XL, with finished bust measurements as follows:
XS: 30–32 inches / S: 34–36 inches / M: 38–40 inches / L: 42–44 inches / XL: 46–48 inches / 2XL: 50–52 inches.
Throughout the pattern, the stitch counts for each size will be listed in order separated by slashes, like this: XS/S/M/L/XL/2XL. Work the number that corresponds to your size. If your measurements fall between sizes, it is generally recommended to size up for crocheted garments and adjust the waist shaping as needed.

Pattern Notes
This dress is worked in several pieces: the front bodice, the back bodice, the skirt (worked in the round after joining the bodice pieces), and two bell sleeves. Read through the entire pattern before beginning so you have a clear picture of how the pieces come together.
The main lace stitch pattern used throughout is worked as follows:
Lace Mesh Stitch (worked flat over a multiple of 2 + 1):
Row 1 (RS): Ch 3 (counts as dc), dc in same stitch, ch 1, sk 1, dc in next st; rep from to end, turn.
Row 2: Ch 4 (counts as dc + ch 1), sk first sp, dc in next dc, ch 1, dc in next dc; rep from to end, working last dc in top of turning ch, turn.
Rep Row 2 for pattern.
Lace Mesh Stitch (worked in the round):
Rnd 1: Ch 3 (counts as dc), ch 1, sk 1, dc in next st; rep from to last st, ch 1, sl st to top of beg ch-3.
Rnd 2: Sl st into first ch-1 sp, ch 3, ch 1, dc in next ch-1 sp; rep from around, ch 1, sl st to top of beg ch-3.
Rep Rnd 2 for pattern.
Front Bodice
Chain 55/61/67/73/79/85.
Row 1 (RS): Dc in 4th ch from hook, ch 1, sk 1, dc in next ch; rep from across. You should have 27/30/33/36/39/42 dc and 26/29/32/35/38/41 ch-1 spaces. Turn.
Work even in the Lace Mesh Stitch as established until the piece measures 13/13.5/14/14.5/15/15.5 inches from the beginning, or your desired bodice length from shoulder to waist. End after a WS row.
Waist Shaping (optional for a more fitted look):
You may work a few rows of single crochet at the waist, decreasing one stitch at each side edge over 2 rows and then increasing back out over the next 2 rows before transitioning to the skirt. This is optional and most crocheters find the natural ease of the lace fabric sufficient.
Armhole Shaping:
When the bodice reaches your desired shoulder-to-armhole measurement (approximately 7.5/7.75/8/8.5/8.75/9 inches from the beginning), you will begin armhole shaping on the next RS row.
At the beginning of the next RS row, sl st across the first 4/4/5/5/6/6 stitches, then work in pattern to the last 4/4/5/5/6/6 stitches, leave those unworked, and turn. Continue working even over the remaining center stitches until the armhole measures 7.5/8/8/8.5/9/9.5 inches. Fasten off.
Back Bodice
Work exactly as the Front Bodice. When both pieces are complete, seam the shoulder seams using a whipstitch or slip stitch join, leaving the center open for the neckline. The neckline opening for this dress is intentionally wide for a relaxed, off-the-shoulder or barely-on-shoulder effect. If you prefer a more traditional neckline, simply increase the number of rows worked in the shoulder seam area.
Seam the side seams from the bottom of the bodice upward, leaving the armhole sections open. At this point you should have a joined bodice with two open armholes and an open bottom edge.
Skirt
Join yarn with a sl st at one side seam at the bottom of the bodice. You will now work in the round, incorporating increases in the first round to transition from the tighter bodice fabric into the fuller skirt.
Set-up Round: Work sc evenly around the entire bottom edge of the bodice, placing 2 sc in every 3rd stitch to increase the stitch count by approximately one third. The exact count is less critical here than achieving an even, full appearance. Join with sl st to first sc. Your approximate stitch count after increases should be 80/90/100/110/120/130. If yours differs slightly, adjust so it is a multiple of 2 for the lace pattern to work out cleanly.
Round 1: Ch 3, ch 1, sk 1, dc in next st; rep from around, sl st to top of beg ch-3.
Work even in the Lace Mesh Stitch in the round for 6 rounds.
Increase Round: In this round, work an increase (work 2 dc instead of 1 dc in every 10th dc stitch) to begin flaring the skirt gently. This round effectively adds approximately 8/9/10/11/12/13 stitches to the circumference.
Continue working even in the Lace Mesh Stitch for 8 more rounds, then work another Increase Round in the same manner.
Repeat this sequence — 8 rounds even, 1 increase round — two more times, or until the skirt reaches your desired length. For a midi-length dress on an average height, the skirt should measure approximately 22 to 25 inches from the waist. For a maxi effect, continue increases and length as desired.
Hem Round: Work a final round of sc around the bottom edge of the skirt, then sl st to join. Fasten off.
Bell Sleeves (Make 2)
The bell sleeves begin at the top of the arm (the shoulder) and increase toward the wrist, creating that signature fluttering bell shape.
Chain 33/35/37/39/41/43.
Row 1 (RS): Dc in 4th ch from hook and in each ch across. You should have 31/33/35/37/39/41 dc. Turn.
Rows 2–6: Work even in the Lace Mesh Stitch pattern.
Begin Bell Increase:
Row 7: Ch 3, dc in same stitch (increase made), work in pattern across to last stitch, 2 dc in last stitch. Turn.
Work this increase on each side every 4th row, 6 times total. You will now have 43/45/47/49/51/53 stitches after all increases are worked.
Continue even until the sleeve measures approximately 14/14/14.5/14.5/15/15 inches from the beginning, or your desired length.
Cuff Edge:
Work 2 rows of sc across the bottom of the sleeve, working a slight increase (every 3rd sc, work 2 sc in the same stitch) in the first of these rows to allow the bell to flare fully open at the wrist. Join and fasten off.
Fold the sleeve with RS together and seam the underarm edge using a whipstitch. Turn RS out.
Attaching the Sleeves
Align the top seam of each sleeve with the shoulder seam of the bodice and pin in place at the armhole opening. Using a yarn needle and a length of matching yarn, carefully seam the sleeve into the armhole using a whipstitch or mattress stitch. Take your time here — even attachment is what makes a garment look professionally finished.
Neckline Finish
Work a single round of sc around the neckline opening, keeping tension even. If desired, work a second round in a simple picot pattern: sc in next 3 sts, ch 3, sl st in first ch of ch-3; rep from around for a delicate, coastal-inspired trim.
Finishing and Blocking
Weave in all ends securely. Wet block the finished dress by soaking it in cool water for 15 to 20 minutes, gently pressing out excess water (never wring or twist), laying it flat on your blocking mat, and shaping it to your measurements. Pin gently if needed and allow it to dry completely, which may take 24 hours or more depending on your yarn.
Blocking is truly the step that makes a crocheted garment come alive. The lace mesh stitch pattern opens up beautifully when blocked, the bell sleeves take on their full, graceful shape, and the skirt drapes in a way that looks genuinely elegant rather than stiff.
Styling Your Coastal Blue Bell Sleeve Crochet Dress
Once your dress is finished and blocked, the fun of wearing it begins. This design is naturally versatile. Wear it over a nude or matching swimsuit for an effortless beach cover-up that looks polished enough for a seaside café lunch. Pair it with strappy sandals and layered shell necklaces for a boho festival look. For an evening event near the water, add wedge heels and simple gold jewelry to let the texture of the dress take center stage.
The coastal blue colorway in particular photographs beautifully in natural light, making this dress a favorite for vacation photos against white sand, turquoise water, or sun-bleached wooden boardwalks.
Care Instructions
For best results, hand wash your finished dress in cool water with a gentle detergent formulated for delicate or natural fibers. Lay flat to dry — never hang a wet crocheted garment, as the weight of the water can cause it to stretch out of shape. If your yarn is machine-washable (always check the label), use the delicate cycle in a mesh laundry bag.
Tips for Customizing This Pattern
One of the greatest joys of making your own clothing is the ability to adapt it entirely to your taste. You can lengthen or shorten the skirt to suit your preference. You can work the sleeves in a contrasting color — imagine a sandy ivory bodice with deep ocean-teal sleeves for a dramatic coastal color-block effect. You can skip the sleeves entirely for a sleeveless sundress. You can add a drawstring waist using a simple chain threaded through a row of chain spaces at the waist seam for a more defined silhouette.
This pattern is also easy to adjust for plus sizes by simply increasing your starting chain count in even increments of two stitches and working the increase rounds slightly more frequently in the skirt. The forgiving nature of the lace stitch means it accommodates a range of body types beautifully.
Final Thoughts
The Coastal Blue Bell Sleeve Crochet Dress is the kind of project that reminds you why you fell in love with crochet in the first place. It is the intersection of function and beauty, of patience and reward. Each row of the lace mesh stitch feels meditative, and watching the garment take shape — from flat panels of fabric to a fully dimensional, wearable dress with elegant flowing sleeves — is genuinely satisfying.
Whether you are making this for yourself or as a gift for someone who loves the ocean, this pattern delivers a result that looks and feels luxurious. Take your time with it, enjoy the process, and do not skip the blocking step. The finished dress will more than justify every hour you invest.
Happy crocheting — and may your next wear be somewhere with salt air and sunshine.
