Free Vest Knitting Pattern: A Classic Layering Piece You’ll Wear All Season
There’s something deeply satisfying about knitting a garment you’ll actually reach for again and again. A well-made vest sits at the top of that list. It layers beautifully over a collared shirt, keeps your core warm without overheating your arms, and works just as well tucked into a Monday morning meeting as it does worn casually on a weekend walk. If you’ve been looking for a free vest knitting pattern that delivers clean lines, a flattering fit, and a project that doesn’t feel overwhelming, you’ve found it.
This pattern is written for intermediate knitters, but adventurous beginners who are comfortable with basic shaping should find it very manageable. We’ll walk through everything together — materials, gauge, sizing, stitch patterns, and detailed row-by-row instructions — so you can cast on with confidence.
Why Knit a Vest?
Before we dive into the pattern itself, let’s take a moment to appreciate why a vest is such a smart knitting project. Compared to a full sweater, a vest uses significantly less yarn, which means a lower material cost and a shorter time commitment. You still get to work through all the interesting parts of garment construction — shaping the armhole, working the neckline, joining pieces — without the added complexity of setting in sleeves.
Vests are also incredibly versatile in terms of yarn choice. Because there’s no sleeve to contend with, you can use slightly heavier or textured yarns without worrying about whether a sleeve will feel stiff or uncomfortable to wear for hours. A chunky merino vest? Lovely. A fine-weight linen blend for warmer months? Equally beautiful.
And perhaps most importantly, a handmade vest is a gift people actually love to receive. If you’ve been searching for a knitting project that makes a meaningful, wearable present, this pattern delivers exactly that.
Materials You’ll Need
For this pattern, we’re working with a worsted-weight yarn, which is one of the most beginner-friendly weights available. It knits up quickly, shows stitch definition clearly, and comes in a huge range of colors.
Yarn: Approximately 600–900 yards of worsted-weight yarn, depending on your size. A smooth wool or wool-blend yarn works beautifully here. Good choices include Cascade 220, Lion Brand Fishermen’s Wool, Paintbox Simply DK (held double), or any comparable worsted that gives you the gauge below.
Needles: US size 7 (4.5mm) circular needles, 24–32 inches in length, or straight needles if you prefer. You’ll also want a set of US size 6 (4.0mm) needles for the ribbing sections.
Notions: Stitch markers (at least 4), tapestry needle for finishing, stitch holders or waste yarn, scissors.
Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch, blocked. Please swatch. I know, I know — everyone says this and very few people do it. But for a fitted garment like a vest, gauge really does matter. A difference of even half a stitch per inch across the width of the body will shift your finished measurements by an inch or more.
Sizing
This pattern is written in six sizes. Finished bust measurements are listed below. Choose your size based on your actual bust measurement plus 2–3 inches of ease for a classic fit, or 4–5 inches for a more relaxed fit.
Size 1: 34 inches finished bust
Size 2: 38 inches finished bust
Size 3: 42 inches finished bust
Size 4: 46 inches finished bust
Size 5: 50 inches finished bust
Size 6: 54 inches finished bust
Throughout the pattern, instructions are written as Size 1 (Size 2, Size 3, Size 4, Size 5, Size 6). When only one number appears, it applies to all sizes.
Pattern Notes
This vest is worked flat in two pieces — a front and a back — then seamed at the shoulders and sides. The armhole bands and neckline are picked up and worked in the round after seaming. If you prefer a seamless construction, this pattern adapts easily to working in the round up to the armhole divide, though the written instructions below use the traditional flat construction.
The body of the vest uses a simple seed stitch border along the sides and hem, with stockinette for the main fabric. This combination keeps the edges from rolling without requiring a separate hem treatment, and the texture adds a subtle visual interest that elevates the finished piece.
All slipped stitches are slipped purlwise with yarn in back unless otherwise noted.

The Back
Cast On
Using your smaller needles (US 6), CO 86 (96, 106, 116, 126, 136) sts using a long-tail cast on or your preferred stretchy method.
Ribbing
Row 1 (RS): K2, p2; rep from to last 2 sts, k2.
Row 2 (WS): P2, k2; rep from to last 2 sts, p2.
Repeat these two rows until ribbing measures 2 inches, ending after a WS row.
Body
Switch to your larger needles (US 7).
Row 1 (RS): K3, p1, k1, p1, knit to last 6 sts, p1, k1, p1, k3.
Row 2 (WS): P3, k1, p1, k1, purl to last 6 sts, k1, p1, k1, p3.
These six-stitch seed stitch borders on each side will be maintained throughout the body of the vest. The center stitches between the borders are worked in stockinette (knit on RS, purl on WS).
Continue in this established pattern until the back measures 13 (13.5, 14, 14, 14.5, 14.5) inches from the cast-on edge, ending after a WS row.
Armhole Shaping
BO 5 (6, 6, 7, 8, 9) sts at the beginning of the next 2 rows.
Next row (RS — decrease row): K2, ssk, work to last 4 sts, k2tog, k2.
Next row (WS): Work even.
Repeat these last 2 rows 4 (5, 6, 7, 8, 9) more times.
You should now have 68 (74, 82, 88, 94, 100) sts remaining.
Continue working even in pattern until the armhole measures 8 (8.5, 9, 9.5, 10, 10.5) inches from the first bind-off row, ending after a WS row.
Shoulder Shaping
BO 7 (8, 9, 10, 10, 11) sts at the beginning of the next 4 rows.
Place remaining 40 (42, 46, 48, 54, 56) sts on a holder for the back neck.
The Front
Work exactly as the back through the armhole shaping. You should have the same stitch count remaining: 68 (74, 82, 88, 94, 100) sts.
Continue working even until the armhole measures 5 (5.5, 6, 6, 6.5, 6.5) inches from the first bind-off row, ending after a WS row. This is shorter than the back armhole because we need room for the front neckline shaping.
Neck Shaping
On the next RS row, work across 24 (27, 30, 33, 35, 38) sts and place them on a holder. BO the center 20 (20, 22, 22, 24, 24) sts. Work to end of row.
You’ll now work each shoulder separately.
Right Shoulder (as worn):
Row 1 (WS): Work even to last 3 sts, p2tog, p1.
Row 2 (RS): K1, ssk, work even to end.
Repeat these two rows 3 (3, 4, 4, 5, 5) more times. You should have 17 (20, 22, 25, 25, 28) sts remaining.
Continue even until the armhole matches the back armhole depth, ending after a WS row.
BO 7 (8, 9, 10, 10, 11) sts at the beginning of the next RS row. Work one WS row even. BO remaining 10 (12, 13, 15, 15, 17) sts.
Left Shoulder (as worn):
Return held stitches to needle and rejoin yarn at neck edge with RS facing.
Row 1 (RS): K1, k2tog, work even to end.
Row 2 (WS): Work even to last 3 sts, ssp, p1.
Repeat these two rows 3 (3, 4, 4, 5, 5) more times.
Continue even until armhole depth matches the back, ending after a RS row.
BO 7 (8, 9, 10, 10, 11) sts at the beginning of the next WS row. Work one RS row even. BO remaining sts.
Finishing the Body
Weave in all ends on both pieces. Block both the front and back before seaming — this step makes a significant difference in how cleanly your seams come together and how the finished vest drapes. Wet blocking or steam blocking both work well for most wool and wool-blend yarns. Pin your pieces to your measurements and allow them to dry completely.
Seaming
Join the shoulder seams using a three-needle bind-off or mattress stitch, whichever you prefer. Both methods create a clean, sturdy seam. If you’ve never tried mattress stitch before, this is a wonderful project to learn it on — the seam becomes virtually invisible from the right side.
Once your shoulder seams are joined, seam the sides of the vest from the hem up to the armhole using mattress stitch.
Armhole Bands
Using your smaller needles (US 6) and with RS facing, pick up and knit stitches evenly around one armhole opening. A good rule of thumb is to pick up approximately 3 stitches for every 4 rows along the straight edges, and one stitch per bound-off stitch along the bottom of the armhole curve.
Join to work in the round and place a marker at the beginning of the round.
Round 1: K2, p2; rep from around. Adjust stitch count by one or two if needed to make your ribbing work out evenly.
Continue in 2×2 rib for 1 inch.
BO loosely in pattern. A stretchy bind-off like the k2tog bind-off or the Jeny’s Surprisingly Stretchy Bind-Off works particularly well here to keep the armhole band from binding across the upper arm.
Repeat for the second armhole.
Neckband
With RS facing and smaller needles, pick up and knit stitches evenly around the entire neckline — across the back neck holder stitches, down the left front neck, across the center front bound-off stitches, and up the right front neck.
Place a marker and join to work in the round.
Work in 2×2 ribbing (k2, p2) for 1 inch, then bind off loosely in pattern.
Final Finishing
Weave in any remaining ends. Give the completed vest one final light blocking, paying particular attention to the armhole bands and neckband to help them lie flat and smooth.
Customizing This Pattern
One of the best things about a simple, well-structured vest pattern is how adaptable it is. Here are a few ways you might want to make this design your own.
Add length. If you prefer a longer, tunic-style vest, simply continue working the body for several more inches before beginning the armhole shaping. Add an inch of length at a time and try the piece on as you go, since different bodies carry length differently.
Adjust the neckline. The neckline as written is a moderate scoop. If you prefer a deeper V-neck, begin your neckline shaping earlier and work a more gradual decrease rate. For a crewneck, begin shaping later and keep the decrease more compact.
Try a different stitch pattern. The seed stitch border pairs beautifully with the stockinette body, but you could replace the stockinette entirely with a simple texture stitch like moss stitch, broken rib, or a small allover seed stitch. Just make sure to re-swatch if you change the stitch pattern, since texture stitches often have slightly different gauge than stockinette.
Experiment with color. A stripe sequence worked in the body, with the bands worked in a solid contrast color, gives this vest an entirely different personality. Even a single stripe of color at the hem or across the chest creates a striking visual effect.
Yarn Substitution Tips
Because this pattern calls for worsted weight, you have a wide world of yarn options to choose from. A few things to keep in mind when substituting.
Fiber content will affect how the finished vest behaves. Wool and wool blends tend to have memory and resilience — they bounce back after wearing and hold their shape well. Cotton and linen yarns are cooler and drapier, which can be wonderful for a spring or summer vest but may make the armhole shaping look slightly different than in a wool version. Acrylic yarns are an excellent choice for anyone with wool allergies and have come a long way in terms of softness and drape.
Always buy an extra skein. Dye lots vary between production runs, and running out of yarn in the middle of a back piece is genuinely heartbreaking.
A Few Words on Gauge and Fit
I want to come back to gauge one more time, because it deserves it. If you knit your swatch and discover you’re getting 19 stitches per 4 inches instead of 20, go up a needle size before you go down a size in the pattern. If you’re getting 21 stitches per 4 inches, go down a needle size. Adjusting your needle size to hit gauge is almost always the right move before you start manipulating the stitch counts in the pattern.
That said, knitters are individuals, and some of us knit looser in the body of a project than we do in a swatch. If you’ve made garments before and have found a consistent pattern in how your gauge shifts, factor that in now. Your future self, wearing a beautifully fitting vest, will thank your past self for taking the extra twenty minutes.
Sharing Your Finished Vest
If you make this vest, I’d genuinely love to see it. Tag your project photos online and share the details of your yarn choices, any modifications you made, and how the fit came out. The knitting community is one of the most generous and inspiring creative communities there is, and every finished object shared becomes a source of encouragement for someone else who’s just learning to knit, or just picking up needles again after years away.
Happy knitting.
