Step-by-Step Crochet Bell Sleeve Top Pattern & Guide

There is something quietly magical about a bell sleeve. The way the fabric gathers at the shoulder and flows outward toward the wrist, catching light and movement at the same time, makes it one of the most romantic silhouettes in handmade fashion. Crocheting your own bell sleeve top takes that magic a step further because every stitch is placed by your own hands, and the finished garment fits your body rather than a standardized mannequin. Whether you are an intermediate crocheter looking for your next wearable project or a confident beginner eager to try something with a little more structure, this pattern and guide will walk you through everything from choosing your yarn to weaving in your last end.

What You Will Need Before You Start

Before picking up your hook, gathering your materials thoughtfully will make the whole process smoother. Here is what you need to work through this pattern comfortably.

Yarn: Choose a lightweight yarn in a DK or light worsted weight. Natural fibers like cotton, linen, or a cotton-bamboo blend are ideal for a top because they drape beautifully, breathe well, and feel pleasant against skin. You will need approximately 800 to 1,200 yards depending on your size, with larger sizes requiring more yardage. Avoid anything too stiff or scratchy, since this garment will sit against your torso and arms for extended periods.

Hook: A 4.0mm to 5.0mm crochet hook works well with DK and light worsted weight yarn. The exact hook size matters less than your gauge, so choose the hook that gives you the correct gauge swatch measurement described below.

Notions: You will need a yarn needle for seaming and weaving in ends, stitch markers in two colors (one for beginning of round markers, one for increase markers), a measuring tape, and scissors. A row counter app or physical counter helps you stay on track through the body section.

Gauge: Before beginning the main pattern, crochet a gauge swatch of at least 5 inches square using your chosen yarn and hook. Block the swatch, then measure. The pattern is written to a gauge of 16 stitches and 18 rows per 4 inches in single crochet. Adjust your hook size up or down until your swatch matches this gauge. Skipping the gauge swatch is the single most common reason a crocheted garment comes out the wrong size, so resist the temptation to skip it.

Sizing: This pattern is written for sizes Small through 2XL. The finished bust measurements are as follows: Small fits a 32–34 inch bust, Medium fits a 34–36 inch bust, Large fits a 36–38 inch bust, XL fits a 38–40 inch bust, and 2XL fits a 40–44 inch bust. Instructions for multiple sizes are written in the format Small (Medium, Large, XL, 2XL). When only one number appears, it applies to all sizes.

Understanding the Stitch Vocabulary

This pattern uses a small set of stitches, which makes it accessible without being overly repetitive. Here is a quick reference before you dive in.

Chain (ch): The foundational stitch used to begin and to form turning chains at the start of rows.

Single crochet (sc): The densest of the basic stitches, used throughout the body of the top to create a firm but flexible fabric that holds its shape.

Half double crochet (hdc): Slightly taller than single crochet and creates a softer, airier fabric. Used in the bell sleeve section to allow for drape.

Double crochet (dc): The tallest stitch used in this pattern, appearing in the bell sleeve flare section to achieve the dramatic widening effect.

Slip stitch (sl st): Used to join rounds and to move yarn position without adding height.

Increase (inc): Two stitches worked into the same stitch, used to add width.

Decrease (dec): Two stitches worked together as one, used to shape the waist and neckline.

Part One: The Body

The body of this top is worked in two flat panels, a front and a back, which are then seamed at the sides. If you prefer seamless construction, notes are provided at the end of this section for working in the round.

The Back Panel

Start by chaining 68 (72, 76, 82, 88).

Row 1: Starting in the second chain from the hook, sc across. You should have 67 (71, 75, 81, 87) stitches. Chain 1 and turn.

Rows 2 through 6: Sc across each row. Chain 1 and turn at the end of each row. These first rows form the ribbed-look hem. If you prefer a more defined ribbed edge, you can work rows 1 through 6 in the back loop only (BLO) of each stitch.

Row 7 through Row 30: Continue sc across all stitches without shaping. This forms the lower body of the top, which hangs straight from hip to waist. Chain 1 and turn at the end of each row.

Waist Shaping Begins at Row 31:

Row 31: Sc 3, dec, sc to last 5 stitches, dec, sc 3. You lose 2 stitches and now have 65 (69, 73, 79, 85) stitches.

Rows 32 through 35: Sc across without decreasing.

Row 36: Sc 3, dec, sc to last 5 stitches, dec, sc 3. Now 63 (67, 71, 77, 83) stitches.

Rows 37 through 40: Sc across without decreasing.

Row 41: Sc 3, dec, sc to last 5 stitches, dec, sc 3. Now 61 (65, 69, 75, 81) stitches. This is the narrowest point of the waist.

Rows 42 through 46: Sc across without shaping.

Bust Shaping Begins at Row 47:

Row 47: Sc 3, inc, sc to last 4 stitches, inc, sc 3. Now 63 (67, 71, 77, 83) stitches.

Rows 48 through 51: Sc across without shaping.

Row 52: Sc 3, inc, sc to last 4 stitches, inc, sc 3. Now 65 (69, 73, 79, 85) stitches.

Rows 53 through 56: Sc across without shaping.

Row 57: Sc 3, inc, sc to last 4 stitches, inc, sc 3. Now 67 (71, 75, 81, 87) stitches.

Continue working even (without shaping) until the back panel measures 18 (18.5, 19, 19, 19.5) inches from the starting chain, ending with a right-side row. Fasten off and set aside.

The Front Panel

Work the front panel exactly as the back panel through all shaping rows. When you reach the point at which the panel measures 14 (14.5, 15, 15, 15.5) inches from the starting chain, you will begin the neckline shaping.

Front Neckline Shaping:

Identify the center of the row. For each size, mark the center stitch or center two stitches with a stitch marker.

Working only the right side first: Sc across to 3 stitches before the center marker. Dec, sc 1. Turn.

Next row: Ch 1, sc 1, dec, sc to end. Turn.

Continue decreasing 1 stitch at the neck edge every other row 4 more times. Then work even on remaining stitches until the front panel matches the back panel in length. Fasten off.

Rejoin yarn at the center of the row and work the left side of the neckline as a mirror image of the right side. Fasten off.

Joining the Panels

Align the front and back panels with right sides facing. Using your yarn needle and a length of yarn, seam both side edges together using a mattress stitch or a whipstitch, leaving the top 7 (7.5, 8, 8.5, 9) inches of each side open as armhole openings. Turn the piece right side out. You now have the body of the top.

Part Two: The Bell Sleeves

The sleeves are where this project becomes truly distinctive. They are worked flat and seamed, then attached to the armhole opening. The bell effect is achieved by transitioning from single crochet at the shoulder into double crochet toward the wrist, which causes the fabric to naturally flare and widen.

Setting Up the Sleeve

Chain 42 (44, 46, 50, 54).

Row 1: Sc in second chain from hook, sc across. 41 (43, 45, 49, 53) stitches. Ch 1, turn.

Rows 2 through 8: Sc across. Ch 1, turn. These rows form the upper sleeve, which is fitted at the shoulder.

Sleeve Cap Shaping (Rows 9 through 16):

Row 9: Sl st across the first 3 stitches, ch 1, sc to last 3 stitches, leave last 3 unworked. Turn.

Row 10: Ch 1, dec, sc to last 2 stitches, dec. Turn.

Repeat Row 10 four more times. You should now have approximately 27 (29, 31, 35, 39) stitches remaining. Work even for 2 rows. Fasten off. This creates the slight curve that allows the sleeve cap to sit cleanly in the armhole.

Transitioning to the Bell Flare

Rejoin yarn at the starting chain edge of the sleeve (the cast-on edge, which will become the wrist edge). You are now going to work downward toward the wrist, transitioning stitch height as you go.

Row 1 (transition): Working along the cast-on edge, sc across all stitches.

Row 2: Hdc across, but work 2 hdc in every third stitch. This begins the flare.

Row 3: Hdc across, working 2 hdc in every fourth stitch.

Row 4: Dc across, working 2 dc in every third stitch.

Row 5: Dc across, working 2 dc in every other stitch.

Row 6: Dc across, working 2 dc in every stitch.

Row 7: Ch 3 (counts as first dc), dc across, working 2 dc in every stitch.

Rows 8 through 10: Ch 3, dc across without additional increases.

The sleeve should now measure approximately 14 to 16 inches from shoulder to wrist hem, and the wrist opening should be dramatically wider than the upper sleeve. If you want an even more exaggerated bell, you can add one or two additional rows of dc with increases at every other stitch before the final flat rows.

Work a simple edging along the bottom hem of the sleeve: join yarn at the side seam edge of the wrist, ch 1, and sc evenly around the entire wrist opening. Sl st to join. Fasten off.

Make two sleeves.

Attaching the Sleeves

With right sides facing, pin the sleeve cap into the armhole opening. The deepest part of the sleeve cap should align with the shoulder seam. Ease any fullness evenly around the armhole opening. Using your yarn needle, seam the sleeve to the armhole opening using a mattress stitch. Repeat on the other side. When both sleeves are attached, seam the underarm and the side edges of the sleeve together from wrist to underarm in one continuous seam.

Part Three: Finishing Details

Good finishing transforms a good crochet project into a polished garment. Take time with these final steps.

Neckline Edging

Join yarn at one shoulder seam. Working with a 3.5mm hook for a slightly tighter edge, sc evenly around the entire neckline, including the front neckline curve and the straight back neckline. Work 3 sc into each corner at the front neckline to prevent the corners from pulling inward. When you reach your starting point, sl st to join. Do not fasten off yet.

Round 2: Ch 1, sc around, decreasing 1 stitch at each inner corner of the neckline (skip 1 stitch at the inside corners) and working 3 sc into each outer corner. Sl st to join. Fasten off.

Hem Edging

Join yarn at one side seam at the bottom edge of the body. Sc evenly around the entire hem. Work 1 round of sc and fasten off. A reverse sc (also called crab stitch) makes a beautifully textured finished edge if you want a bit more visual detail at the hem: after the first round of sc, work backward (from left to right instead of right to left) with sc stitches to create the crab stitch effect.

Weaving In Ends

Thread each yarn tail onto your yarn needle and weave it through the back of the stitches in a back-and-forth motion, changing direction twice to anchor it securely. Trim any excess yarn close to the fabric.

Blocking

Blocking is the single greatest finishing technique available to a crocheter, and it is especially important for garments. Soak the finished top in cool water for 15 to 20 minutes until fully saturated. Gently press out excess water (do not wring or twist) and lay the garment flat on a blocking mat or clean towel. Shape it gently to the correct measurements, smoothing out any uneven stitches and encouraging the bell sleeves to lie open and flat. Allow it to dry completely before wearing or photographing. You will be amazed at how much more professional the piece looks after blocking.

Tips for Customizing This Pattern

One of the best parts of making your own garment is the freedom to adjust it to your preferences. Here are a few ideas for making this pattern your own.

If you prefer a cropped top, simply work fewer rows on the body before beginning the armhole. A finished body length of 12 inches rather than 18 creates a stylish crop that pairs well with high-waisted bottoms.

For a more dramatic neckline, increase the neckline depth by another 2 to 3 inches on the front panel. A deep V-neck or a wide square neckline both look stunning with bell sleeves.

Adding a crochet lace trim to the bell sleeve wrist edge instead of the simple sc edging gives the garment a more romantic, vintage feel. Any simple 2- or 3-row lace edging worked with shell stitches or picots will complement the bell shape beautifully.

If you want to add a waist tie or drawstring for adjustable fit, work a row of evenly spaced chain-2 eyelets along the waist at the narrowest point of the shaping. A thin twisted cord or a length of ribbon threaded through creates a cinched look.

Color-blocking is another wonderful option. Work the body in one color, the sleeves in a contrasting color, and perhaps the edging in a third. Three skeins of different coordinating shades in the same yarn base creates a cohesive look without feeling chaotic.

Troubleshooting Common Issues

My sleeves look too stiff at the shoulder. This usually means your gauge is slightly tight or that you are using a yarn with too little drape. Try blocking more aggressively around the shoulder seam, or switch to a bamboo or modal blend for the sleeves on your next attempt.

The bell flare looks uneven. Check that your increases are spaced consistently across each row. It helps to place stitch markers at each increase point during the transition rows so you can see the flare developing evenly.

My top is pulling at the sides. This is typically a gauge issue. If the fabric is pulling inward, your gauge is too tight. If it is buckling outward, your gauge may be too loose. Both issues are corrected by swatching before you begin, but if you are already mid-project, blocking can sometimes correct mild pulling.

The neckline curls. Single crochet edging at the neckline can sometimes curl if worked too loosely. Add a second round of sc or work with a hook one size smaller than you used for the body.

Final Thoughts

A crocheted bell sleeve top is one of those projects that manages to feel both ambitious and deeply wearable at the same time. The finished garment photographs beautifully, transitions between seasons with the right layering, and earns the kind of compliments that always lead to the question, “Did you make that yourself?” The answer, of
