There is something deeply satisfying about finishing a wearable garment that fits beautifully, works up relatively quickly, and becomes one of those pieces you reach for again and again. The Sina Vest is exactly that kind of project. Whether you are a seasoned knitter looking for your next confident make or an adventurous intermediate knitter ready to tackle your first seamless garment, the Sina Vest offers everything you could want: clean lines, a flattering silhouette, and the kind of versatility that makes it a true wardrobe staple.

In this guide, you will find a complete free knitting pattern for the Sina Vest, along with detailed notes on materials, sizing, construction, and finishing so that your project goes smoothly from cast-on to bind-off. Grab your favorite yarn, settle into your most comfortable chair, and let’s get started.

What Is the Sina Vest?

The Sina Vest is a sleeveless pullover worked in the round from the bottom up. It features a relaxed but structured fit with a ribbed hem and neckline, a subtle waist shaping, and a classic V-neck or round-neck option that you can choose based on your personal preference. The name Sina, derived from Scandinavian origins meaning “to follow” or associated with a sense of quiet strength, suits the garment perfectly — it is understated, confident, and endlessly wearable.

The vest is designed to be layered over a fitted long-sleeve tee in winter or worn alone over high-waisted trousers or a midi skirt in warmer months. It works beautifully in solid colors that show off the stitch texture, but it is equally lovely in heathered or tonal yarns that add visual depth without overwhelming the clean design.

Materials and Tools

Before diving into the pattern, let’s talk about what you will need to gather.

Yarn: The Sina Vest is designed for a worsted weight yarn, which makes it a great project if you have been building up a stash of your favorites. You will need approximately 700 to 1,200 yards depending on your size, with smaller sizes using less and larger sizes requiring more. Look for a yarn with good stitch definition and a bit of drape — merino wool blends, wool-cotton blends, or even a plant-based yarn like Pima cotton or linen work beautifully here. Avoid yarns that are too fuzzy or halo-heavy, as these can obscure the rib detail and make it harder to see your stitches clearly while you work.

Needles: You will need a US 7 (4.5mm) 32-inch circular needle for the body, a US 6 (4.0mm) 32-inch circular needle for the ribbing, and a set of US 6 (4.0mm) double-pointed needles or a shorter circular for finishing the armholes and neckline. If you knit tightly, you may want to go up a needle size. If you knit loosely, consider going down a size. Always swatch.

Notions: Stitch markers in at least two colors (you will use one color to mark the beginning of the round and a second color for waist shaping points), a tapestry needle for weaving in ends, scissors, and a tape measure. A set of locking stitch markers or scrap yarn for holding stitches is also helpful when you divide for the armholes.

Gauge

Gauge is especially important for a fitted garment like a vest. Take the time to knit a proper swatch, wash it the same way you intend to wash the finished vest, and measure it carefully after it has dried flat.

The target gauge for the Sina Vest is 18 stitches and 26 rows per 4 inches (10 cm) in stockinette stitch on the larger needle. If your gauge is off by even half a stitch per inch, the finished garment can end up several inches too large or too small in the body, which makes a significant difference in fit.

If you have more stitches than the pattern calls for per 4 inches, your knitting is too tight and you should go up a needle size. If you have fewer stitches, your knitting is too loose and you should go down a needle size.

Sizing

The Sina Vest is written in six sizes designed to fit a range of bust measurements. Choose your size based on your actual bust measurement plus your desired ease. This vest is designed with two to three inches of positive ease, meaning the finished garment will be slightly larger than your body measurement for a comfortable, slightly relaxed fit.

Size 1 fits a 32–34 inch bust (finished bust approximately 35 inches). Size 2 fits a 34–36 inch bust (finished bust approximately 38 inches). Size 3 fits a 36–38 inch bust (finished bust approximately 41 inches). Size 4 fits a 40–42 inch bust (finished bust approximately 44 inches). Size 5 fits a 44–46 inch bust (finished bust approximately 47 inches). Size 6 fits a 48–50 inch bust (finished bust approximately 51 inches).

If you fall between sizes, knit the larger size if you prefer more ease or the smaller size if you prefer a more fitted look. The waist shaping can also be adjusted to add or reduce the amount of nipping in at the waist.

Abbreviations

Throughout the pattern, the following abbreviations are used. K means knit. P means purl. K2tog means knit two stitches together (a right-leaning decrease). Ssk means slip, slip, knit (a left-leaning decrease). M1R means make one right (a right-leaning increase). M1L means make one left (a left-leaning increase). PM means place marker. SM means slip marker. BOR means beginning of round. RS means right side. WS means wrong side. St or sts means stitch or stitches. Rep means repeat. Rnd or Rnds means round or rounds. CO means cast on. BO means bind off.

The Pattern

Hem Ribbing

Using the smaller needle (US 6), cast on the following number of stitches using a long-tail cast on or your preferred stretchy cast on method.

Size 1: 158 sts. Size 2: 172 sts. Size 3: 186 sts. Size 4: 198 sts. Size 5: 212 sts. Size 6: 228 sts.

Join to work in the round, being careful not to twist your stitches. PM to mark the beginning of the round.

Work in 2×2 ribbing (k2, p2) for 2 inches. For sizes where the stitch count is not a multiple of 4, work the ribbing as k2, p2 until the last 2 sts of the round, then k2. This creates a tidy, flexible hem that will hug your hips comfortably.

Body

Switch to the larger needle (US 7). You will now work in stockinette (knit every round) until you reach the waist shaping section.

Work even in stockinette for 1.5 inches after the ribbing.

Waist Shaping — Decrease Round: On the next round, work to 3 stitches before the side marker, k2tog, k1, SM, k1, ssk. Work to 3 stitches before the BOR marker, k2tog, k1, SM, k1, ssk. You have decreased 4 stitches total.

Note: To set up the side markers, divide your total stitch count in half and place a second marker at the halfway point. This marks the side seam position.

Repeat the decrease round every 8 rounds twice more. After all three decrease rounds, you will have decreased 12 stitches total.

Work even for 1 inch.

Waist Shaping — Increase Round: On the next round, work to 1 stitch before the side marker, M1R, k1, SM, k1, M1L. Work to 1 stitch before the BOR marker, M1R, k1, SM, k1, M1L. You have increased 4 stitches total.

Repeat the increase round every 8 rounds twice more. After all three increase rounds, you will have increased 12 stitches total, returning to your original stitch count.

Work even in stockinette until the body measures 14 inches from the cast-on edge, or your desired length to underarm. If you are taller or shorter than average, feel free to add or subtract length here. This is the best place to customize the fit.

Dividing for Front and Back

At this point, you will separate the body into front and back to work each piece flat (back and forth in rows).

Knit to the side marker. Place the next half of your stitches on a holder or scrap yarn — these are your front stitches. Continue working the back stitches only, turning your work.

Back:

You will work the back flat in stockinette (knit on RS rows, purl on WS rows).

Armhole Shaping:

At the beginning of the next two rows (one RS row and one WS row), bind off the following number of stitches for the underarm.

Size 1: BO 5 sts each side. Size 2: BO 5 sts each side. Size 3: BO 6 sts each side. Size 4: BO 6 sts each side. Size 5: BO 7 sts each side. Size 6: BO 8 sts each side.

After the initial bind-off, work armhole decreases as follows on RS rows only: K2, ssk, knit to last 4 sts, k2tog, k2.

Repeat this decrease row every RS row 3 (3, 4, 4, 5, 5) times.

Work even in stockinette until the armhole measures 8.5 (9, 9, 9.5, 9.5, 10) inches, ending on a WS row.

Shoulder and Back Neck Shaping:

On the next RS row, bind off the shoulder stitches and the back neck stitches. The exact counts depend on your size — you will bind off approximately one third of your remaining stitches on each shoulder, leaving the center third for the back neck. Place the center back neck stitches on a holder.

For all sizes, work short rows or a simple bind-off to shape the shoulder. A simple approach is to bind off all shoulder stitches on one row after the armhole is complete, leaving the center back neck stitches on a holder to be picked up for the neckband later.

Front:

Return the held front stitches to your needle and work the armhole shaping mirroring the back exactly. After completing the armhole decreases, work even until the armhole measures approximately 4 (4, 4, 4.5, 4.5, 5) inches, ending on a WS row.

V-Neck Option:

On the next RS row, work to the center 2 stitches. Place a marker. Join a second ball of yarn and work to end.

Working both sides at the same time with separate yarn, decrease 1 stitch at each neck edge on every RS row as follows: on the left side, knit to last 3 sts before the neck edge, k2tog, k1. On the right side, k1, ssk, knit to end.

Continue decreasing every RS row until you have the same number of shoulder stitches as the back. Work even until the front matches the back length. Bind off shoulder stitches.

Round Neck Option:

Work even until the armhole measures 6 (6, 6, 6.5, 6.5, 7) inches. On the next RS row, bind off the center front neck stitches (approximately 20 to 24 stitches depending on your size), then decrease 1 stitch at each neck edge every RS row 4 times. Work even until front matches back. Bind off shoulder stitches.

Joining the Shoulders

Once both the front and back are complete, seam the shoulders together using the three-needle bind-off for a clean, strong join. This method creates a tidy seam on the inside of the garment and a subtle ridge on the outside that can also be worn as a design detail on the outside if you prefer.

Armhole Finishing

Using the smaller needle and starting at the underarm, pick up and knit stitches around the armhole edge. Pick up approximately 3 stitches for every 4 rows along the vertical edges and 1 stitch for each bound-off stitch at the underarm. The exact number does not need to be precise, but aim for a multiple of 4 to work the ribbing evenly.

Join to work in the round. Work 2×2 ribbing (k2, p2) for 1 inch. Bind off using a stretchy bind-off, such as the Jeny’s Surprisingly Stretchy Bind-Off or simply binding off in pattern (knitting the knit stitches and purling the purl stitches as you bind off).

Repeat for the second armhole.

Neckband

Pick up and knit stitches around the neck opening, beginning at one shoulder seam. For the V-neck, pick up stitches along the left front neck, place a marker at the center V point, pick up along the right front neck, then pick up across the back neck stitches from the holder.

Work in 2×2 ribbing for 4 rounds. For the V-neck, decrease at the center V marker on each round by working ssk before the marker and k2tog after the marker. Bind off in pattern using a stretchy bind-off.

For the round neck, simply work 2×2 ribbing for 4 to 6 rounds and bind off in pattern.

Finishing

Weave in all your ends carefully, working the tails back and forth through the wrong side of the work rather than simply knotting them. A well-woven end will stay secure through many washes.

Wet block your vest by soaking it in cool water for 20 minutes, gently pressing out the excess water in a towel without wringing, then pinning it to a foam blocking mat in the desired dimensions. Allow it to dry completely before wearing.

Blocking is a step that many knitters are tempted to skip, but it truly transforms a handknit garment. It evens out the tension, opens up the stitches, sets the ribbing, and helps the vest drape beautifully on the body. It is well worth the extra day of waiting.

Tips for Customizing Your Sina Vest

One of the most enjoyable aspects of knitting your own garments is the ability to make them truly yours. Here are a few ideas for putting your own stamp on the Sina Vest.

You can lengthen or shorten the body easily before the underarm divide — simply add or subtract inches at the even section after the waist shaping is complete. This is a great modification if you are petite and find most vest patterns hit you in an awkward spot, or if you are tall and want more coverage.

Yarn substitution opens up a world of possibilities. A smooth merino in a jewel tone makes the vest feel polished and elevated. A rustic wool in a natural undyed shade gives it an earthy, artisan quality. A cotton-linen blend makes it a breezy summer layer. As long as you achieve the gauge, the choice is yours.

You can also experiment with stripes. Because the body is worked in the round and the color changes happen at the beginning of the round, carrying yarn up the inside for small striping sections is simple and leaves very few ends to weave in.

For knitters who prefer a bit more structure, adding a small pocket on the front is a lovely touch. A simple horizontal pocket worked over 20 to 24 stitches placed just above the waist is both practical and charming.

Caring for Your Finished Vest

Most natural fiber yarns recommended for this pattern can be hand-washed in cool water with a gentle wool wash. Lay flat to dry away from direct sunlight or heat sources, which can cause fibers to felt or fade. If you used a plant-based yarn like cotton or linen, you may be able to machine wash on a gentle cycle, but always check the yarn label first.

Storing your vest folded rather than hung will prevent the shoulders from stretching over time. If you knit it in wool, a small cedar sachet or lavender bag nearby will help deter moths.
