Coastal Blue Bell Sleeve Crochet Dress: Free Pattern for a Breezy, Beachside Look

There is something undeniably romantic about a handmade dress that moves with the ocean breeze. The kind of garment that catches the light just right, drapes softly against your skin, and carries with it the quiet satisfaction of knowing you made every stitch yourself. If you have been searching for a project that combines elegant drape, coastal color, and a touch of vintage silhouette, this Coastal Blue Bell Sleeve Crochet Dress pattern is exactly what you need. Whether you are a seasoned crocheter ready for a wearable challenge or an adventurous intermediate maker looking to stretch your skills, this pattern is designed to be achievable, beautiful, and entirely free.

Let’s dive into everything you need to know — materials, gauge, sizing, stitch notes, and the full written pattern — so you can get started right away.

Why You Will Love This Pattern

The bell sleeve silhouette has been a beloved design in fashion for centuries, and for good reason. The way fabric gathers at the shoulder and flows outward at the wrist creates a look that is simultaneously dramatic and effortless. When translated into crochet, especially in a soft coastal blue yarn, the effect is absolutely stunning. This dress features a fitted bodice with gentle shaping, a flowy skirt that skims the body beautifully, and those signature bell sleeves that give the whole piece its beachy, bohemian character.

The stitch pattern used throughout the body and skirt is a combination of double crochet mesh and shell stitches, which creates an open, breathable fabric ideal for warm weather wear. The bodice uses a denser stitch construction for structure and support, while the skirt fans out with gradual increases that give it movement without bulk.

This is the kind of dress you wear to a seaside wedding, a summer farmers market, a beach bonfire, or simply a long afternoon of walking barefoot through warm sand. It photographs beautifully, packs lightly, and pairs with everything from strappy sandals to bare feet.

Materials You Will Need

Before you begin, gather the following supplies. Having everything on hand before you start will make the process much smoother and more enjoyable.

Yarn: Approximately 800–1,200 yards (depending on your size) of DK weight or light worsted weight yarn in a soft coastal blue. Look for yarns with a slight sheen or cotton blend for the best drape. Suggested options include Lion Brand Comfy Cotton Blend, We Are Knitters The Cotton, or Paintbox Yarns Simply DK. A 100% cotton or cotton-linen blend will give you the most breathable, structured drape.

Hook: US Size G/6 (4.0 mm) for the bodice, US Size H/8 (5.0 mm) for the skirt and sleeves. Adjust hook size as needed to match gauge.

Notions: Stitch markers (at least 6), yarn needle for weaving in ends, scissors, measuring tape, 3–5 buttons or a zipper for the back closure (optional), blocking mats and pins for finishing.

Gauge (bodice): 16 stitches and 18 rows = 4 inches in single crochet with G hook. Always check your gauge before starting. A difference of even half a stitch per inch will significantly affect the finished measurements of a garment.

Gauge (skirt and sleeves): 14 stitches = 4 inches in the shell mesh pattern with H hook.

Sizing Guide

This pattern is written for sizes XS through XL. The key measurements are bust circumference, waist circumference, hip circumference, and total dress length from shoulder to hem. Choose your size based on your actual measurements, keeping in mind that the bodice has minimal ease (0–1 inch) while the skirt has generous ease for movement.

XS: Bust 32″, Waist 24″, Hip 34″, Length 42″
S: Bust 34″, Waist 26″, Hip 36″, Length 43″
M: Bust 36″, Waist 28″, Hip 38″, Length 44″
L: Bust 38–40″, Waist 30–32″, Hip 40–42″, Length 45″
XL: Bust 42–44″, Waist 34–36″, Hip 44–46″, Length 46″

Instructions are written for size Small, with changes for larger sizes noted in parentheses throughout the pattern as follows: S (M, L, XL).

Pattern Notes

This dress is worked in pieces — a front bodice, back bodice, skirt (worked in the round from the waist down after joining bodice pieces), and two sleeves — then seamed together. If you prefer seamless construction, notes are included for adapting the bodice to work in the round, though the back opening will need to be added with a split.

The shell mesh stitch used in the skirt and sleeves is a four-row repeat. Once you have worked the repeat twice, the rhythm becomes intuitive and the pattern moves quickly.

Always chain 3 at the beginning of a double crochet row and count it as your first dc unless otherwise instructed. When working the shell pattern, the center dc of each shell from the previous row lines up with the ch-2 space of the v-stitch in the current row, and vice versa.

The Full Pattern

Part One: Front Bodice

With the G hook, chain 62 (66, 72, 78).

Row 1 (WS): Sc in second ch from hook and in each ch across. Turn. [61 (65, 71, 77) sc]

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

Row 5 (Dart Row): Ch 1, sc in first 14 (15, 17, 19) sts, hdc in next 3 sts, dc in next 5 sts, hdc in next 3 sts, sc in next 11 (13, 13, 13) sts, hdc in next 3 sts, dc in next 5 sts, hdc in next 3 sts, sc in last 14 (15, 17, 19) sts. Turn.

Rows 6–10: Ch 1, sc in each st across. Turn.

Repeat Rows 5–10 two more times. This creates subtle bust shaping without darts that pull or pucker.

Continue working in sc until bodice measures 7 (7.5, 8, 8.5) inches from foundation chain.

Armhole Shaping: Sl st across first 5 (6, 7, 8) sts, ch 1, sc across to last 5 (6, 7, 8) sts, leave remaining sts unworked. Turn. [51 (53, 57, 61) sts]

Work even in sc for 6 (6.5, 7, 7.5) more inches.

Neck Shaping: Work across first 16 (17, 19, 21) sts. Turn. Work even for 1 inch on these sts for the right shoulder strap. Fasten off. Skip center 19 (19, 19, 19) sts and rejoin yarn to work the left shoulder strap in the same manner. Fasten off.

Part Two: Back Bodice

Work the back bodice exactly as the front bodice through the armhole shaping. When you reach the neck shaping section, work both shoulder straps the same width as the front. Leave the center back open; you will add a border and button loop closure after assembly.

Part Three: Skirt

After seaming the shoulder straps and side seams of the bodice (leaving armholes open for sleeves), you will pick up stitches around the bottom edge of the bodice to begin the skirt.

With the H hook and RS facing, join yarn at the right side seam at the waist edge.

Foundation Round: Ch 3 (counts as first dc), work dc evenly around the entire waist edge, placing approximately 1 dc per sc row. Join to top of ch-3 with sl st. Count your stitches. You want a total that is a multiple of 6, plus 2. Adjust by adding or skipping a stitch or two as needed. For size S, aim for approximately 98 sts.

Round 1 (V-stitch Round): Ch 5 (counts as dc + ch 2), sk next 2 sts, v-stitch in next st, sk 2 sts, rep from around. Join. [approximately 32 v-stitches for size S]

Round 2 (Shell Round): Sl st into ch-2 sp of first v-stitch, ch 3, 4 dc in same sp (half shell to begin), ch 1, shell in ch-2 sp of next v-stitch, rep from around, ch 1. Join to top of ch-3.

Round 3: Ch 5, v-stitch in ch-1 sp between shells, rep from around. Join.

Round 4: Rep Round 2.

Repeat Rounds 1–4 (or Rounds 3–4 alternating with the v-stitch round) throughout the skirt, adding increase rounds every 8–10 rows to flare the skirt gradually.

Increase Round: Work each v-stitch as (dc, ch 2, dc, ch 2, dc) to add an extra shell position every few repeats. Space your increases evenly around to keep the skirt symmetrical.

Continue the shell mesh pattern until skirt measures 28 (29, 30, 31) inches from waist, or until the dress reaches your desired length. End with a v-stitch round.

Hem Border: Work one final shell round, then ch 1 and work one round of sc through the back loop only to create a clean finished edge. Fasten off.

Part Four: Bell Sleeves

The bell sleeves are worked from the shoulder down, starting with a narrow cap and expanding into the signature flared bell.

With the H hook, join yarn at the center of the armhole with a sl st.

Foundation Round: Ch 3, work dc evenly around the armhole opening — approximately 44 (48, 52, 56) sts. Join.

Rounds 1–4: Work even in the shell mesh pattern (same v-stitch and shell rounds as the skirt).

Bell Increase Section: Beginning in Round 5, work an increase round every other round: in each v-stitch round, add one extra v-stitch per 6 stitches, spaced evenly. This will cause the sleeve to flare outward progressively.

Continue until the sleeve measures 14–16 inches from the armhole, or to your preferred length. The final circumference of the bell at the cuff should be approximately 20–26 inches, depending on how dramatic you want the flare.

Cuff Border: Work one final shell round, then one round of sc in back loop only for a clean edge. Fasten off.

Repeat for the second sleeve.

Assembly

With your yarn needle and a length of yarn, seam the side edges of the bodice using a whipstitch or mattress stitch. Seam the shoulder straps to the back bodice, aligning them neatly at the top. If you prefer a button-back closure, work a single crochet border along both center back edges of the bodice, then add button loops evenly spaced on one side and sew buttons to the other.

Finishing and Blocking

Blocking is what takes a handmade crochet garment from “homemade” to “handcrafted.” It opens up the stitches, evens out the tension, and allows the mesh pattern in the skirt and sleeves to relax into its full, airy beauty.

To block, wet the dress thoroughly (a bathtub works well for this), gently press out excess water without wringing, then lay flat on your blocking mats. Use rust-proof pins to shape the hem, sleeves, and neckline. Smooth the bodice flat and pin the bottom edge. Allow to dry completely — this may take 24–48 hours depending on your fiber and climate. Cotton dries more slowly than acrylic but holds its blocked shape beautifully.

Once dry, weave in all remaining ends with your yarn needle, burying tails into the back of the fabric for at least an inch in two directions for security.

Styling Your Coastal Blue Bell Sleeve Dress

The color choice here is intentional. Coastal blue — that particular shade somewhere between soft sky and deep sea — is one of the most wearable and flattering neutrals in warm weather dressing. It photographs beautifully against sandy beaches, whitewashed walls, lush greenery, and golden afternoon light. It pairs naturally with warm tans, bright whites, soft coral accents, and natural textures like rattan and linen.

Wear this dress with a wide-brimmed straw hat and leather sandals for a breezy coastal afternoon. Layer it over a simple white slip for added coverage and a more structured silhouette. Belt it loosely at the waist with a braided or woven belt to emphasize the shape. Tuck a few wildflowers into the neckline and let the bell sleeves do all the work.

For photographs, find natural light in the early morning or the golden hour before sunset. The open shell stitches in the skirt and sleeves will catch the light in a way that looks absolutely magical on camera.

Tips for Customizing This Pattern

One of the greatest joys of making your own clothing is the ability to make it uniquely yours. Here are a few easy ways to customize this pattern without significantly altering the construction.

You can shorten the skirt to knee length or even mini length for a more playful summer look. You can lengthen the skirt to maxi length by simply continuing the shell mesh pattern for more rounds. The bell sleeves can be shortened to three-quarter length or even capped sleeves by working fewer rounds before the increase section. You can add a contrast color hem border, a crochet lace trim at the neckline, or small crocheted flowers along the waist seam for extra decoration.

Swap the coastal blue for a warm terracotta, a dusty sage, or a soft blush and the dress takes on an entirely different character — each just as beautiful as the last.

Yarn Substitution Advice

If the suggested yarn is unavailable in your area, look for any DK or light worsted weight yarn with good stitch definition and adequate drape. Avoid yarns that are too stiff or too loosely spun, as they will either create a fabric that doesn’t flow or one that distorts too easily. A yarn with at least some natural fiber content — cotton, linen, bamboo, or a cotton-acrylic blend — will give you the best results for a summer dress.

Before committing to a full skein purchase, work a small swatch in the shell mesh pattern and wash it the way you intend to care for the finished dress. Some yarns relax and soften dramatically after washing, while others tighten. Knowing this in advance will save you from surprises once the dress is complete.

There is patience in it, creativity in it, and a deep personal satisfaction in wearing something that exists because your hands made it so. This Coastal Blue Bell Sleeve Crochet Dress is the kind of project that stays with you — you will remember making it, the hours of stitching, the moment you blocked it and saw it take shape on the mat, the first time you wore it out into a warm summer afternoon.
