Ribbed Crochet Sweater Vest | Free Pattern & Video Tutorial
There is something deeply satisfying about a project that looks complex but works up quickly, and a ribbed crochet sweater vest is exactly that kind of make. Whether you are brand new to crochet or have been at it for years, this project strikes that perfect balance between technique and reward. The rich, textured ribbing creates a polished, store-bought look that feels elevated without requiring advanced skills, and the vest silhouette means you can skip the sleeves entirely — a welcome shortcut that still delivers a finished garment you will be proud to wear or gift.
In this post, you will find everything you need: a complete free pattern with written instructions, sizing guidance, yarn recommendations, and a walkthrough of the key techniques. If you are more of a visual learner, the video tutorial linked below will walk you through every stitch in real time so nothing gets lost in translation.
Why a Ribbed Sweater Vest?
Sweater vests have made a confident comeback in recent years, and the crochet version earns its place in any handmade wardrobe. The beauty of a vest is its versatility. Layer it over a crisp button-down shirt for a smart, preppy aesthetic, wear it over a turtleneck for cozy winter styling, or drape it over a flowy blouse for something more relaxed and bohemian. Because there are no sleeves, it adapts beautifully across seasons — light enough for spring evenings and warm enough for layering in autumn.
The ribbed texture specifically deserves extra attention. Ribbing in crochet creates vertical lines that are both visually striking and structurally useful. It adds stretch and recovery to the fabric, which means the vest will hug your body gently rather than pulling at the shoulders or hanging boxy in ways that can make garments look unfinished. That natural elasticity also makes it far more forgiving in terms of fit — a few rows of difference will rarely cause a noticeable issue the way it might in a more rigid stitch pattern.
From a learning perspective, this project is a wonderful opportunity to master the back loop only (BLO) technique and the slip stitch rib method, both of which will serve you in dozens of future projects from hats to bags to blanket borders.
Yarn and Materials
Choosing the right yarn sets the foundation for everything else. For a ribbed sweater vest, you want a yarn that has some structure and body so the ribs stay defined, but also enough softness that it is comfortable against the skin — especially important if you plan to wear it without layers underneath.
Yarn weight: Worsted weight (category 4) is the sweet spot for this pattern. It works up quickly, the stitch definition is clear, and there are endless color options available in almost every price range. You could also use a DK weight (category 3) for a slightly drapier, more delicate result, though your stitch count will need adjusting.
Fiber: A wool or wool-blend yarn brings the best elasticity and stitch memory, which really helps the ribbing pop. If you prefer something machine-washable, look for superwash merino blends or acrylic yarns with a matte finish — the matte texture shows ribbing far better than anything shiny or silky. Cotton is an option for warmer climates, though it lacks natural stretch and may cause the ribbing to look slightly flatter.
Amount needed: For a size small/medium (finished bust approximately 36–38 inches), plan on around 600–700 yards. A medium/large will need closer to 750–900 yards. Always buy an extra skein if you are uncertain — running out mid-project is one of the most frustrating things that can happen, and leftover yarn is never a waste.
Hook size: A 5.0mm (H/8) hook works well with standard worsted weight, but always crochet a gauge swatch first. The pattern is written for a gauge of 14 stitches and 18 rows per 4 inches in the main ribbing stitch.
Additional materials: A yarn needle for weaving in ends and seaming, stitch markers, scissors, and a measuring tape.
Sizing
This pattern is written for sizes XS through 2XL with finished bust measurements as follows:
XS: 32–34 inches | S: 36–38 inches | M: 40–42 inches | L: 44–46 inches | XL: 48–50 inches | 2XL: 52–54 inches
For a comfortable fit with a slight amount of ease, choose the size closest to your actual bust measurement. If you prefer a more oversized, relaxed silhouette — which is a very popular aesthetic right now — size up by one or two sizes.

ch — chain | sl st — slip stitch | sc — single crochet | hdc — half double crochet | dc — double crochet | BLO — back loop only | FLO — front loop only | rep — repeat | st(s) — stitch(es) | sp — space | RS — right side | WS — wrong side | sk — skip | pm — place marker | rm — remove marker | t-ch — turning chain
Stitch Glossary
Slip Stitch Rib: This is the primary stitch used throughout the vest. To work a slip stitch rib, insert your hook into the back loop only of the next stitch, yarn over, and pull through both loops on your hook in one motion. This creates a tight, dense fabric with pronounced vertical ridges. The key to beautiful ribbing is consistent tension — try to keep each stitch the same depth throughout.
Foundation Single Crochet (FSC): Rather than chaining and then working into the chain, the FSC creates the foundation chain and the first row of single crochet simultaneously. This gives you a much stretchier starting edge, which is particularly useful at the hem and neckline of a garment. If you prefer, you can substitute a standard chain followed by a row of single crochet.
The Pattern
Front Panel
Foundation: Using the FSC method or a standard chain, create a foundation of 64 (70, 76, 84, 90, 98) stitches.
Row 1 (RS): Working in BLO, sl st in each stitch across, turn. (64, 70, 76, 84, 90, 98 sl sts)
Row 2 (WS): Ch 1, sl st BLO in each stitch across, turn.
Repeat Row 2 until the piece measures 12 (12.5, 13, 13, 13.5, 14) inches from the foundation edge, or until it reaches your desired length from hem to underarm. This length can be customized freely — if you want a cropped vest, stop a few inches earlier. If you want a longer, more relaxed silhouette, add rows until you are happy.
Armhole Shaping: This is where we begin shaping the openings for your arms.
Row 1 of shaping: Sl st across the first 6 (7, 8, 9, 10, 11) stitches, then continue in BLO sl st pattern across the next 52 (56, 60, 66, 70, 76) stitches, leave the remaining 6 (7, 8, 9, 10, 11) stitches unworked. Turn.
Continue in pattern, decreasing 1 stitch at each armhole edge every row 4 (4, 5, 5, 6, 6) times. You will have 44 (48, 50, 56, 58, 64) stitches remaining after all decreases.
Continue even in pattern until the armhole depth measures 8 (8.5, 9, 9, 9.5, 10) inches.
Neck and Shoulder Shaping:
Next row: Work across 14 (16, 17, 19, 20, 22) stitches, place marker, bind off the center 16 (16, 16, 18, 18, 20) stitches, work to end. Turn.
Working on the left shoulder only, decrease 1 stitch at the neck edge every row 3 times. Work even on remaining 11 (13, 14, 16, 17, 19) stitches until armhole measures the full depth noted above. Fasten off. Rejoin yarn to right shoulder and repeat shaping in mirror image.
Back Panel
Work exactly as the front panel through the armhole shaping. After the armhole decreases are complete, continue even until the piece is 1.5 inches shorter than the front panel total length. This allows the back neckline to sit slightly higher than the front, which is a classic vest detail.
Back Neck Shaping:
Work across 14 (16, 17, 19, 20, 22) stitches, bind off the center 16 (16, 16, 18, 18, 20) stitches for the back neck, work to end. Work each shoulder separately for 2 rows, decreasing 1 stitch at the neck edge on each row. Fasten off remaining shoulder stitches.
Assembly
Hold the front and back panels with right sides facing. Using your yarn needle and a length of yarn, seam the shoulder seams using a whip stitch or mattress stitch — either works beautifully with this fabric. Then seam the side seams, leaving the armhole openings free.
Finishing
The finishing on this vest makes a significant difference in the final look, so do not rush this step.
Hem border: With RS facing, attach yarn at any point along the bottom hem. Work 1 round of single crochet evenly around the entire hem edge, being consistent about how many stitches you work per inch so the edge does not ruffle or pull. Join with a slip stitch. For a crisper finish, work a second round in BLO single crochet. Fasten off and weave in ends.
Neckline border: Attach yarn at one shoulder seam. Work single crochet evenly around the entire neckline, including the front V-shape if you opted for a V-neck modification. At the bottom point of the V, work 3 stitches into the same stitch to allow the fabric to lie flat. Join, fasten off.
Armhole borders: Work the same single crochet edging around each armhole opening. These create a clean, finished look and prevent the fabric from stretching out with wear. A round of reverse single crochet (also called crab stitch) after the plain single crochet round adds a beautiful, slightly rolled edge that looks extremely polished.
Weave in all remaining ends securely, wet block the finished vest by soaking it in cool water, gently squeezing out excess moisture, and laying it flat to dry in the measurements you want. Blocking transforms the piece — the stitches even out, the ribbing relaxes into its full depth, and the vest looks genuinely professional.
Video Tutorial
If any part of the written pattern feels unclear, the video tutorial is there to fill in the gaps. The video covers the slip stitch rib technique step by step from the very first stitch, demonstrates how to work the armhole and neckline shaping, and shows the full finishing process including the crab stitch edging. Watching someone else’s hands move through the stitches can make all the difference when you are learning a new technique or working through a tricky row.
The video is especially useful for understanding tension in the slip stitch rib — this stitch has a tendency to tighten up for newer crocheters, and seeing it demonstrated at a comfortable, even pace helps train your hands to find the right rhythm. Pause, rewind, and replay as many times as you need.
Customization Ideas
One of the most enjoyable things about making your own garments is the ability to adapt them to your exact preferences. Here are a few ways to make this vest completely your own.
Color: The pattern works beautifully in a single solid color where the texture does all the talking, but it also looks stunning in a classic marled or heathered yarn that adds visual depth without introducing complexity. If you are feeling adventurous, try working the body in one color and the borders in a contrasting shade for a color-blocked effect.
Length: As mentioned earlier, this pattern is very easy to shorten into a cropped silhouette — extremely trendy at the moment and a great option if you are working with a limited yardage. Conversely, adding length below the hip creates more of a longline vest that works beautifully belted over wide-leg trousers.
Neckline: The standard pattern uses a rounded crew neck, but it is simple to modify this into a V-neck by beginning your neck decreases earlier and working them more gradually. A deep V-neck gives the vest a more dramatic, fashion-forward look while the rounded neck reads as more classic and cozy.
Pockets: A single patch pocket worked in the same ribbed stitch and sewn onto the front panel is a charming and practical addition. Work a small rectangle approximately 5 by 5 inches, finish the top edge with a row of reverse single crochet, and whip stitch it onto the vest wherever feels most natural.
Buttons: A row of small buttons down one side seam or along the shoulder seam adds structure and a handcrafted detail that elevates the whole piece. This is particularly effective when worked in a contrast color.
Troubleshooting Common Issues
My ribbing looks uneven. This is almost always a tension issue. Try consciously relaxing your grip on the hook and allowing slightly more yarn to feed through with each stitch. Blocking will also even out minor inconsistencies beautifully.
The vest is pulling at the armholes. This usually means the armhole border was worked too tightly. If you have not yet fastened off, try working into the stitches with a larger hook for the edging rows. If you have already finished, a gentle wet block can often relax the opening.
My finished measurements do not match the pattern. Gauge differences are the most common culprit. A small difference in gauge — even half a stitch per inch — multiplies over the width of a garment and can result in a significantly different size. Always, always work a gauge swatch before beginning a garment, and adjust your hook size up or down as needed to match the stated gauge.
The slip stitch rib is too stiff. This is normal with newer crocheters who tend to work tightly. Try going up one hook size — you may end up working on a 5.5mm or 6.0mm hook rather than 5.0mm while still producing a fabric that looks and behaves the same way. What matters is that your gauge swatch matches, not which specific hook size you used to get there.
Sharing Your Make
If you make this vest, sharing it with the crochet community is one of the most rewarding parts of the whole process. Tag your project on Instagram, Ravelry, or Pinterest so others can see your version and get inspired to make their own. There is something genuinely wonderful about seeing the same pattern interpreted in fifty different yarns and colorways — every single one looks different, and every single one is right.
