Crochet Sweater Vest Pattern for Fall Layering: Sizes XS to 5XL
There is something quietly satisfying about a sweater vest. It gives you the warmth of a knit without committing to sleeves, which means you can layer it over a flowy blouse, a crisp button-down, or even a long-sleeved tee and let the outfit do the talking. This crochet sweater vest pattern is designed specifically for fall layering, with an easy stitch pattern that works up beautifully in a chunky or worsted weight yarn and a size range that spans from XS all the way to 5XL — because cozy should be available to everyone.
Whether you are a crocheter with a few projects under your belt or someone who has been making garments for years, this pattern is approachable and satisfying to complete. You can finish it in a weekend with bulkier yarn, or take your time with a lighter worsted weight and enjoy the meditative rhythm of the stitches. Either way, the result is a polished, wearable piece that looks like it came from a boutique rather than a craft basket.
Let’s get into everything you need to know to make this your new favorite fall staple.
Materials You Will Need
Before you cast on — or rather, before you make your foundation chain — gather your supplies so you can work without interruption.
Yarn: The recommended yarn for this pattern is a worsted weight (category 4) or bulky weight (category 5) yarn in a fiber blend that has some structure to it. A wool-acrylic blend works wonderfully because it holds its shape wash after wash and still gives you that warm, natural feel. For a crisp look, try a smooth yarn. For something with more texture, a tweedy or heathered yarn adds visual interest without requiring any extra stitch work on your part.
Yardage varies significantly by size, so here is a general guide based on a worsted weight yarn at the recommended gauge:
XS: approximately 600 yards
S: approximately 700 yards
M: approximately 800 yards
L: approximately 900 yards
XL: approximately 1,000 yards
2XL: approximately 1,150 yards
3XL: approximately 1,300 yards
4XL: approximately 1,450 yards
5XL: approximately 1,600 yards
If you are working with a bulky weight yarn, reduce yardage estimates by about 20 percent, but always buy an extra skein — running out mid-project is a crocheter’s least favorite plot twist.
Hook: A size 5.0 mm (H/8) hook for worsted weight, or a 6.0 mm (J/10) hook for bulky weight. As always, your gauge swatch is the true authority here, not the hook size printed on the label.
Notions: A yarn needle for weaving in ends, scissors, stitch markers (at least four), and a measuring tape. If you want to add buttons as a decorative detail at the shoulder or along a split hem, you will need those as well, along with a sewing needle and matching thread.
Gauge
Gauge is one of those things that feels like a suggestion until you finish a vest that fits a small child when you needed it to fit you. Please, take the time to swatch.
For worsted weight at 5.0 mm hook:
14 stitches x 16 rows = 4 inches in the main stitch pattern (half double crochet)
For bulky weight at 6.0 mm hook:
12 stitches x 14 rows = 4 inches in the main stitch pattern
Wash and dry your swatch the way you plan to wash your finished vest before measuring, because some yarns — especially natural fibers — bloom or shrink after their first wash.
Sizing and Measurements
This vest is worked in two flat panels (front and back) and seamed at the shoulders and sides, with a simple ribbed hem and armhole edging worked after assembly. The sizing is based on finished garment measurements with approximately 2 to 4 inches of positive ease built in, which is ideal for layering over long sleeves.
Here are the finished chest measurements for each size:
XS: 34 inches
S: 38 inches
M: 42 inches
L: 46 inches
XL: 50 inches
2XL: 54 inches
3XL: 58 inches
4XL: 62 inches
5XL: 66 inches
The body length (from shoulder to hem) is 24 inches for XS through L, 25 inches for XL through 2XL, and 26 inches for 3XL through 5XL. If you are shorter or taller, you can easily add or subtract rows from the body before beginning the armhole shaping. Just make a note of how many rows you changed so you can match the front and back panels.

Stitch Pattern
The main stitch used throughout the body of this vest is half double crochet worked in both loops. It creates a dense, squishy fabric with just enough drape to look elegant rather than stiff. The ribbing at the hem and armhole edges is worked in hdc through the back loop only, which gives it the stretch needed to lie flat against the body.
If you want to add visual texture, you can substitute the main body stitch with a simple moss stitch (alternating sc and ch 1, worked in the spaces of the previous row), though this will change your gauge and yardage requirements. The written instructions below use standard hdc unless otherwise noted.
Pattern Instructions
Back Panel
Foundation: Chain the number of stitches listed for your size:
XS: 60 ch
S: 67 ch
M: 74 ch
L: 81 ch
XL: 88 ch
2XL: 95 ch
3XL: 102 ch
4XL: 109 ch
5XL: 116 ch
Row 1 (WS): Hdc in the 3rd chain from hook and in each chain across. Turn. (Chain counts as first hdc.)
Rows 2 through end of body: Ch 2, turn. Hdc in each stitch across.
Continue working in this manner until the panel measures the body length for your size from the foundation chain. At this point, you will begin the armhole shaping.
Armhole Shaping (Back)
The armholes are created by working decreases at both ends of your rows. Seam your shoulder width will be approximately one-third of your total stitch count, with the armhole taking up the space between.
Row 1 of armhole shaping: Sl st across the first 6 (6, 7, 7, 8, 8, 9, 9, 10) stitches. Ch 2, hdc in each stitch until 6 (6, 7, 7, 8, 8, 9, 9, 10) stitches remain. Leave last stitches unworked. Turn.
Rows 2 through 4: Ch 2, hdc2tog over first two stitches, hdc across until 2 stitches remain, hdc2tog. Turn. (Decrease 2 stitches per row.)
After the initial armhole shaping, continue working even (no more decreases) until the armhole measures:
XS to M: 8 inches
L to XL: 8.5 inches
2XL to 3XL: 9 inches
4XL to 5XL: 9.5 inches
Shoulder and Neck Shaping (Back)
Divide remaining stitches into thirds. The center third will become the back neck, and the two outer sections will become the left and right shoulders.
Work the right shoulder first: Ch 2, hdc across to center neck section. Turn. Work 2 more rows on these stitches only, then fasten off. Reattach yarn to the left shoulder section and repeat. Leave center neck stitches on hold or mark them — you will pick them up for the neckband later.
Front Panel
Work the front panel exactly as the back until the piece measures approximately 4 inches less than the back’s total length. This is where you will begin the front neck shaping.
Front Neck Shaping
Divide: Work across to the center of your stitch count. Place a marker at the exact center stitch. If your stitch count is odd, the center stitch belongs to neither side — skip it and begin the right side of the neck on the following stitch.
Left front neck: Ch 2, hdc across to center marker. Turn. On the next row, work across until 2 stitches remain, hdc2tog. Turn. Repeat this single decrease at the neck edge every other row a total of 6 times. Then continue working even on remaining shoulder stitches until the front matches the back length at the shoulder. Fasten off.
Right front neck: Reattach yarn at the center of the front panel, RS facing. Ch 2, hdc across. Turn. On the next row, ch 2, hdc2tog, hdc across. Repeat neck decreases every other row 6 times, then continue even to match the back. Fasten off.
Armhole Shaping (Front)
The front armhole shaping is worked exactly like the back armhole shaping, timed to happen at the same row in the piece. If you made any length adjustments earlier, make sure both panels have the same number of rows before the armhole shaping begins.
Assembly
Lay both panels on a flat surface with right sides facing each other. Line up the shoulder edges and pin generously — this is the step that makes the difference between a vest that looks handmade and one that looks hand-crafted.
Using a yarn needle and a length of matching yarn, seam the shoulders together using the mattress stitch or a simple whip stitch. The mattress stitch gives a nearly invisible seam that lies flat, which is ideal for a polished finish on a garment.
Next, seam the side edges of the front and back panels together from the hem up to the armhole, leaving the armholes open. Pin again before stitching, checking that the hem edges are even on both sides.
Edging
Hem Ribbing
With right side facing, attach yarn to the bottom edge of one side seam. Chain 5. Hdc in the 3rd chain from hook and across (3 hdc). Sl st into the edge of the next 2 rows of the body fabric to anchor the rib. Turn.
Work back across the rib stitches in hdc blo. Sl st into the next 2 rows of the body edge. Turn.
Continue this attached ribbing all the way around the hem until you return to your starting point. Sl st to join and fasten off. The ribbing will naturally pull the hem in just slightly, giving the vest a tailored look at the bottom.
Neckline Edging
With right side facing, attach yarn at one shoulder seam. Work one round of hdc evenly around the entire neckline opening, decreasing at the corners of the V-neck by working 3 stitches together (hdc3tog) at the bottom point of the V to keep it lying flat. Sl st to join. Fasten off and weave in ends.
For a deeper ribbed neckband, work attached ribbing as described for the hem, working around the neckline instead. This gives a more structured, fitted look and keeps the neckline from stretching over time.
Armhole Edging
With right side facing, attach yarn at one underarm seam. Work one round of hdc evenly around the entire armhole opening. Sl st to join. For XL and above, you may want to work a second round of ribbing to keep the armhole trim rather than allowing it to flare.
Finishing Touches
Weave in all remaining ends with a yarn needle, taking care to work the tail back and forth through several stitches in different directions so it does not work free over time. Steam block your finished vest if you are using a natural fiber or blend — lay it flat on a blocking mat, pin it gently to your finished measurements, and steam without pressing the iron directly onto the surface. Allow it to dry completely before wearing.
If you want a more polished look, you can add a row of reverse single crochet (also called the crab stitch) around the neckline or armholes. It creates a neat, twisted cord effect that looks intentional and refined.
Styling Your Crochet Sweater Vest for Fall
The beauty of a vest is its range. Here are some ways to wear this one through the season.
Over a white button-down shirt with wide-leg trousers, the vest becomes office-appropriate and quietly chic. Pair it with loafers and you have an outfit that works for everything from a morning meeting to an afternoon farmer’s market.
Layered over a fitted long-sleeved tee and tucked into high-waisted jeans, it gives a casual, put-together look that is perfect for weekend errands, coffee with friends, or an afternoon walk through falling leaves.
For a more bohemian feel, try wearing it over a floral or printed long-sleeve dress, letting the hem of the dress peek out below the vest. Add ankle boots and you have something that feels effortless and styled at the same time.
Because this vest has a classic V-neck shape and clean lines, it works with prints, patterns, and textures underneath without competing. Choose a yarn color that complements your existing wardrobe — deep burgundy, warm camel, forest green, and soft oatmeal are all particularly beautiful for fall and layer well over a range of base layers.
Tips for Sizing Up or Down
If you want to adjust the length of the vest, add or subtract rows from the body section before armhole shaping in multiples of 1 inch (roughly 4 to 5 rows at worsted gauge). Keep in mind that a longer vest will require more yarn.
If you find that your gauge swatch is slightly off and your vest is coming out narrower than expected, go up a hook size rather than recalculating all your stitch counts. Similarly, if it is coming out too wide, go down a hook size. A small change in hook size can mean a significant change in finished measurements over a large number of stitches.
For a more oversized look — especially beautiful in XS through M — size up one or even two sizes from your actual measurements. The extra ease creates beautiful drape and makes the vest feel relaxed and cozy.
For a more fitted look at larger sizes, size down by one from your actual measurements, especially if you are on the lower end of a size range.
Care Instructions
Always refer to your yarn label for specific washing instructions, as fiber content varies. Most wool-acrylic blends can be hand-washed in cool water with a gentle detergent and laid flat to dry. Avoid hanging your vest to dry, as the weight of wet yarn can stretch the fabric out of shape over time. For yarns that are machine washable, use the gentle or delicate cycle and a mesh laundry bag for extra protection.
