Free Pattern: V-Neck Sweater Vest for Any Season

There is something timeless about a well-made sweater vest. It sits comfortably at the intersection of casual and polished, works over a simple t-shirt in autumn or layered under a blazer in winter, and translates beautifully from one season to the next without requiring much fuss. If you have been looking for a knitting project that feels both satisfying and genuinely wearable, this free V-neck sweater vest pattern is exactly what you need.

This pattern is designed to be accessible for knitters at the intermediate level, though a confident beginner who has completed a few simple garments will find it very manageable. We will walk through every step together — from choosing your yarn and understanding your gauge to shaping the armholes, working the V-neck decrease, and finishing the edges with a clean, professional look. The result is a classic, structured vest with a deep V-neck that flatters a wide range of body types and can be customized easily to suit your personal style.

Why You Will Love This V-Neck Sweater Vest Pattern

Before we dive into the materials and instructions, it is worth talking about why this particular style of garment deserves a place in your knitting queue.

The sweater vest has had a remarkable cultural journey. Once considered the domain of golfers and prep school students, it has fully re-entered mainstream fashion and become a staple piece in contemporary wardrobes. Designers have put it on runways, stylists have paired it with everything from midi skirts to wide-leg trousers, and everyday knitters have embraced it as one of the most versatile handmade garments you can create.

What makes the V-neck version especially appealing is the way it elongates the torso and frames the neckline. A deep V draws the eye upward, works beautifully with necklaces or statement collars on a shirt underneath, and gives the garment a slightly more formal, put-together feeling than a crewneck version. At the same time, it stays relaxed and comfortable — this is not a fussy piece.

From a practical knitting standpoint, a vest is also a wonderful project because you skip the sleeves entirely. If you have ever started an ambitious sweater and stalled out somewhere around the second sleeve, you will understand the appeal of a project that requires only a front and a back. It is faster to complete, uses less yarn, and gives you all the satisfaction of a finished wearable garment in a fraction of the usual time.

Materials You Will Need

To knit this V-neck sweater vest, gather the following materials before you begin.

Yarn: Approximately 600–900 yards of worsted weight yarn (the exact yardage depends on your size; more on that shortly). This pattern works beautifully in a smooth wool or wool-blend, which gives good stitch definition and a classic look. Cotton or cotton blends are excellent for a warmer-weather version, keeping the vest breathable and lightweight. Avoid very fuzzy or heavily textured yarns on your first attempt, as they can make it harder to see your stitches clearly, especially during the shaping sections.

Recommended yarn weight: Worsted (also labeled as 10-ply or Aran weight in some countries). The label should indicate approximately 200 yards per 100g skein. For a size small/medium, three skeins will typically be sufficient. For a large/XL, plan for four to five skeins.

Needles: US size 7 (4.5mm) straight or circular needles for the main body. US size 6 (4.0mm) needles for the ribbing at the hem, armhole bands, and neckband. If you prefer to work in the round, you will also want a 16-inch circular needle in size 6 for the neckband and armhole bands.

Notions: Stitch markers, a tapestry needle for seaming and weaving in ends, stitch holders or scrap yarn to hold stitches, a tape measure, and scissors.

Gauge

Gauge is not optional in garment knitting. I know that is something knitters hear constantly and often ignore, but please take the time to swatch for this project. The fit of your finished vest depends entirely on your gauge being accurate.

Target gauge: 20 stitches and 28 rows = 4 inches (10 cm) in stockinette stitch, blocked.

Knit a swatch of at least 6 inches square using your chosen yarn and size 7 needles. Wash and block your swatch the way you intend to wash your finished vest. Let it dry completely, then measure your gauge in the center of the swatch, away from the edges.

If you have more stitches per inch than the target, go up a needle size. If you have fewer stitches per inch, go down a needle size. Keep adjusting until your gauge matches, and only then cast on for the actual project.

Sizing

This pattern is written for sizes XS, S, M, L, XL, and 2XL. The finished measurements are as follows, with the numbers in parentheses representing larger sizes in order throughout the pattern.

Finished bust: 32 (36, 40, 44, 48, 52) inches. This vest is designed with 2 inches of positive ease, meaning the finished garment will be 2 inches larger than your actual bust measurement. If you prefer a more relaxed, oversized fit, choose one size up. If you like a closer fit, go down a size.

Finished length from hem to shoulder: 23 (23.5, 24, 24.5, 25, 25.5) inches.

Pattern Notes and Abbreviations

Before beginning, familiarize yourself with these abbreviations used throughout the pattern.

CO = cast on. BO = bind off. K = knit. P = purl. St(s) = stitch(es). RS = right side. WS = wrong side. K2tog = knit two stitches together (a right-leaning decrease). SSK = slip, slip, knit (a left-leaning decrease). PM = place marker. SM = slip marker. Rep = repeat.

All pieces are worked flat (back and forth in rows). The neckband and armhole bands are worked in the round after seaming.

The Back

Cast on 80 (90, 100, 110, 120, 130) stitches using your size 6 needles and the long-tail cast on method, which creates a neat, slightly stretchy edge that works beautifully for ribbing.

Ribbing: Work in K2, P2 rib for 2.5 inches, ending with a wrong-side row.

Switch to your size 7 needles.

Body: Work in stockinette stitch (knit on RS, purl on WS) until piece measures 14 (14, 14.5, 14.5, 15, 15) inches from cast on edge, ending with a WS row.

Armhole Shaping:

Row 1 (RS): BO 5 (5, 6, 7, 8, 9) sts at beginning of row, knit to end.
Row 2 (WS): BO 5 (5, 6, 7, 8, 9) sts at beginning of row, purl to end.
Row 3 (RS): K1, SSK, knit to last 3 sts, K2tog, K1.
Row 4 (WS): Purl across.

Repeat Rows 3 and 4 a total of 4 (5, 5, 6, 7, 8) times.

You should now have 62 (70, 78, 84, 90, 96) stitches remaining.

Continue in stockinette without further shaping until armhole measures 9 (9.5, 9.5, 10, 10, 10.5) inches from the first bind-off row, ending with a WS row.

Shoulder Shaping:

Row 1 (RS): BO 7 (8, 9, 10, 10, 11) sts, knit to end.
Row 2 (WS): BO 7 (8, 9, 10, 10, 11) sts, purl to end.
Row 3 (RS): BO 7 (8, 9, 10, 11, 11) sts, knit to end.
Row 4 (WS): BO 7 (8, 9, 10, 11, 11) sts, purl to end.

Place the remaining 34 (38, 42, 44, 48, 52) stitches on a holder for the back neck.

The Front

Cast on 80 (90, 100, 110, 120, 130) stitches using size 6 needles.

Work ribbing as for the back: K2, P2 rib for 2.5 inches, ending with a WS row.

Switch to size 7 needles and work in stockinette until piece measures the same length as the back to the armhole shaping, ending with a WS row.

Armhole and V-Neck Shaping (worked simultaneously):

This is the most important section of the pattern, and it requires your full attention. The armhole shaping happens on both sides of the work at the same time as the V-neck shaping begins in the center. Take it one step at a time and you will do beautifully.

First, shape the armholes exactly as you did for the back:

Row 1 (RS): BO 5 (5, 6, 7, 8, 9) sts, knit to end.
Row 2 (WS): BO 5 (5, 6, 7, 8, 9) sts, purl to end.

Then begin the V-neck shaping on the next RS row.

Dividing for the V-neck:

Row 3 (RS): K1, SSK, knit to the center of the row. Place the second half of the stitches on a holder. Turn work.

You will now work each side of the front separately.

Left Front (as worn):

Continue the armhole decrease at the armhole edge (beginning of RS rows) for the remaining decrease rows as established, while simultaneously decreasing for the V-neck at the neck edge (end of RS rows):

Neck decrease row (RS): Knit to last 3 sts, K2tog, K1.

Work a neck decrease on every RS row 10 (12, 13, 14, 16, 18) more times, then every 4th row 3 (3, 4, 4, 4, 4) times, while completing armhole decreases as established.

After all shaping is complete, continue straight in stockinette until the armhole measures the same as the back armhole, ending ready to shape the shoulder.

Shoulder Shaping (Left Front):

Row 1 (WS): BO 7 (8, 9, 10, 10, 11) sts, purl to end.
Row 2 (RS): Knit across.
Row 3 (WS): BO remaining 7 (8, 9, 10, 11, 11) sts.

Right Front (as worn):

Rejoin yarn at the neck edge of the held stitches with RS facing.

Row 1 (RS): K1, SSK (neck decrease), knit to last 3 sts, K2tog, K1 (armhole decrease). Continue as for Left Front, mirroring all shaping: armhole decreases at the end of RS rows, neck decreases at the beginning of RS rows using SSK.

Work shoulder shaping on RS rows to mirror the left front.

Finishing

Block both pieces before seaming. Wet blocking is recommended: soak the pieces in cool water for 20 minutes, gently press out excess water in a towel, lay flat to your finished measurements, and allow to dry completely. Blocking evens out your stitches and makes seaming dramatically easier.

Seaming: Using a tapestry needle and your project yarn, seam the shoulders using the Kitchener stitch or three-needle bind-off for a nearly invisible join. Sew the side seams using mattress stitch, working from the right side of the fabric for a clean, professional finish.

Neckband

With RS facing and size 6 circular needle, beginning at the right shoulder seam, pick up and knit stitches around the entire neck opening. Pick up approximately 3 stitches for every 4 rows along the diagonal V-neck sections, and knit across the held back neck stitches.

Place a marker at the center of the V-neck point.

Work in K1, P1 rib for 1 inch, working a double decrease at the V-point marker on every round as follows: slip 2 sts together knitwise, K1, pass slipped stitches over (a centered double decrease). This keeps the neckband lying flat and angled properly at the V.

Bind off loosely in pattern. A stretchy bind-off, such as the sewn bind-off or the Jeny’s Surprisingly Stretchy Bind-Off, works wonderfully here.

Armhole Bands

With RS facing and size 6 circular needle, pick up and knit stitches evenly around the armhole opening. Work in K1, P1 rib for 1 inch. Bind off loosely in pattern.

Repeat for the second armhole.

Weave in all ends securely. Give your finished vest one final light blocking if needed, paying particular attention to the neckband and armhole bands.

Tips for Customizing Your Vest

One of the best things about knitting your own garments is the freedom to make them entirely your own. Here are a few ways to personalize this pattern.

If you want a cropped version, simply work fewer rows in the body section before beginning the armhole shaping. Stopping at around 11 or 12 inches of body length creates a modern cropped vest that sits just at the natural waist.

For a deeper V-neck, begin your V-neck shaping a few rows before the armhole shaping instead of simultaneously with it. This creates a longer, more dramatic V.

A contrast color ribbing is a simple and striking modification. Use a different color for the hem ribbing, the neckband, and the armhole bands. This can completely transform the look of the vest with minimal extra effort.

If you would prefer a fully seamless construction, you can work the body in the round up to the armhole shaping, then divide and work each section flat from that point forward. The finish and drape may be slightly different depending on your yarn, so a swatch worked both flat and in the round is worthwhile if you go this route.

Yarn Substitution Suggestions

This pattern is quite forgiving when it comes to yarn choice, but a few guidelines will help you make a great decision.

For a classic, four-season vest, look for a smooth worsted weight wool or wool-blend with good stitch definition. Brands like Cascade 220, Lion Brand Wool-Ease, and Paintbox Simply DK (held double) all work beautifully and are widely available at accessible price points.

For a summer-weight or transitional vest, a cotton or linen blend will give you a relaxed, breathable fabric. Drops Paris, Lion Brand 24/7 Cotton, and Paintbox Cotton DK are all excellent choices that hold their shape well and wash easily.

For a luxurious, special-occasion version, consider a cashmere blend or a soft merino. The added cost is well worth it for a vest you will reach for constantly.

Caring for Your Finished Vest

Hand washing in cool water with a gentle wool wash is the safest approach for most yarns used in this pattern. Lay flat to dry, reshaping to your measurements as needed. Avoid hanging a wet knit garment, as the weight of the water can stretch it out of shape.

If you used a machine-washable yarn, check the label for the manufacturer’s recommendations. Many modern superwash wools can be machine washed on a gentle cycle in a mesh bag, which makes regular wear and care much more practical.

Store your vest folded rather than hung to maintain its shape over time.

A Note on Fit

If you are between sizes or have different measurements for your bust versus your hips, it is worth taking the time to do a few simple modifications before casting on. Knitting the body to a larger size and then tapering up to your preferred shoulder size through waist shaping is very achievable, and many knitters find that a small amount of waist shaping — a few strategic decreases and increases along the sides — transforms a boxy vest into something that feels truly tailored.
