Relaxed Crochet Coco Vest Pattern for Casual Outfits

There is something deeply satisfying about crocheting a garment that you actually want to wear every single day. Not a decorative piece that sits in a drawer, not an ambitious project that ends up slightly unwearable — but a real, go-to piece that earns its place in your regular rotation. The Coco Vest is exactly that kind of project. It is relaxed, effortlessly stylish, and the kind of thing you will reach for whether you are running errands, meeting friends for coffee, or layering up for a breezy evening on the patio.

This pattern is designed with wearability at the front of every decision. The silhouette is easy and generous without being shapeless. The stitch work is interesting enough to keep you engaged through every row but approachable enough that you do not need years of crochet experience to finish it beautifully. If you have been crocheting for at least a few months and are comfortable with basic stitches, you are ready to make the Coco Vest.

Let us get into everything you need to know: materials, sizing, stitch guide, and the full row-by-row pattern instructions.

Why the Coco Vest Works for Casual Outfits

Before diving into the yarn and hook sizes, it helps to understand why this vest works so well as a casual wardrobe staple. The design draws on the oversized, textured look that has been popular in handmade knitwear for several years now, but with a crochet twist that gives it a slightly more structured edge. Unlike knitted vests, a crocheted vest holds its shape beautifully and drapes in a way that flatters a wide range of body types.

The Coco Vest has an open front, meaning it works as a layering piece over a simple fitted t-shirt, a flowy blouse, or even a casual button-down. The armhole openings are generous, so it slides on and off easily and does not restrict movement. The hem falls somewhere between hip and mid-thigh depending on your height, giving it that versatile length that works equally well with jeans, wide-leg trousers, or even a midi skirt.

The name “Coco” came from the idea of a garment that is understated but quietly chic — the crochet equivalent of a well-cut linen blazer. It does not demand attention, but it earns it.

Materials You Will Need

Getting your materials right before you cast on is one of the most important things you can do to make sure your finished vest turns out the way you want it to. Here is a full list of what you will need.

Yarn: The Coco Vest is designed for a worsted weight yarn, which gives you that satisfying drape without being too heavy. Look for something with a good amount of drape rather than a stiff, structured yarn. Cotton-blend yarns are wonderful for this project because they breathe well, hold their shape after washing, and come in an enormous range of colors. A cotton-acrylic blend is a great choice if you want something slightly more forgiving and easier to care for. You will need approximately 600 to 900 yards depending on your size.

Hook: A size 5.5mm (I-9) crochet hook is recommended as a starting point, but you should always crochet a swatch first. The right hook for you is whatever gives you the correct gauge, not necessarily the size printed on the label.

Notions: You will need a yarn needle for weaving in ends, a pair of scissors, and a few stitch markers to help you keep track of your place. A tape measure is essential for checking your gauge swatch and measuring the finished pieces as you go.

Gauge: 14 stitches and 16 rows in half double crochet equals 4 inches by 4 inches. Please do not skip your gauge swatch. Even a small difference in gauge will change the finished dimensions of your vest significantly, and since this is a garment, fit really matters.

Sizing Information

The Coco Vest is written in six sizes to accommodate a wide range of bodies. The sizing is based on finished bust measurements, and the vest is designed with four to six inches of positive ease, meaning it will be that much larger than your actual bust measurement. This is intentional — the relaxed, oversized fit is part of the design.

The six sizes are as follows: Size 1 fits a finished bust of 36 to 38 inches. Size 2 fits 40 to 42 inches. Size 3 fits 44 to 46 inches. Size 4 fits 48 to 50 inches. Size 5 fits 52 to 54 inches. Size 6 fits 56 to 58 inches.

To choose your size, measure your actual bust and add four to six inches to find your target finished measurement. For example, if your bust measures 38 inches and you like a relaxed fit, you would choose Size 2 for a finished bust of around 42 inches. If you prefer a more dramatic oversized silhouette, go up a size.

Throughout the pattern, instructions for all sizes will be written in the format Size 1 (Size 2, Size 3, Size 4, Size 5, Size 6). Always follow the numbers that correspond to your chosen size.

Abbreviations and Stitch Guide

Before you begin, make sure you are familiar with the following abbreviations used throughout this pattern.

Ch means chain. Sl st means slip stitch. Sc means single crochet. Hdc means half double crochet. Dc means double crochet. St means stitch. Sts means stitches. Rep means repeat. Sk means skip. Sp means space. RS means right side. WS means wrong side. BLO means back loop only.

This pattern uses a simple combination of half double crochet and a basic v-stitch variation to create a lightweight, slightly open fabric that is perfect for a layering vest. The main body is worked in hdc through both loops unless otherwise noted, which gives the fabric a smooth, even appearance. The borders are worked in single crochet to create a clean, tidy edge.

Pattern Instructions

The Coco Vest is worked in two separate flat panels — a front panel and a back panel — which are then seamed together at the shoulders and sides, leaving the armholes open. This construction method is beginner-friendly and gives you easy control over the fit before you sew anything up.

Back Panel

Begin by chaining 64 (70, 76, 82, 88, 94).

Row 1 (RS): Starting in the third chain from the hook, hdc across. You should have 62 (68, 74, 80, 86, 92) stitches. Chain 2 and turn.

Row 2: Hdc across. Chain 2 and turn.

Repeat Row 2 until your piece measures 13 (13.5, 14, 14, 14.5, 14.5) inches from the foundation chain, ending with a WS row. This is your lower body section.

Begin Armhole Shaping for Back

The armhole shaping creates the openings for your arms and defines the shoulder width. Work as follows.

Row 1 (Armhole Row, RS): Sl st across the first 6 (6, 7, 7, 8, 8) stitches. Chain 2 (does not count as a stitch here). Hdc across until 6 (6, 7, 7, 8, 8) stitches remain. Leave those remaining stitches unworked. You will now have 50 (56, 60, 66, 70, 76) stitches. Chain 2 and turn.

Row 2: Hdc2tog at the beginning of the row, hdc across to the last two stitches, hdc2tog. Chain 2 and turn. You have decreased by 2 stitches.

Row 3: Hdc across. Chain 2 and turn.

Repeat Rows 2 and 3 a total of 2 (2, 3, 3, 4, 4) more times. You will now have 44 (50, 52, 58, 60, 66) stitches.

Continue working even in hdc with no more decreases until your armhole measures 8 (8.5, 9, 9, 9.5, 9.5) inches. Fasten off.

Front Panel

The front panel begins exactly like the back panel.

Chain 64 (70, 76, 82, 88, 94).

Row 1 (RS): Starting in the third chain from the hook, hdc across. You should have 62 (68, 74, 80, 86, 92) stitches. Chain 2 and turn.

Row 2: Hdc across. Chain 2 and turn.

Repeat Row 2 until your piece measures 13 (13.5, 14, 14, 14.5, 14.5) inches from the foundation chain, just like the back panel.

Begin Armhole Shaping for Front

Work the armhole shaping exactly as you did for the back panel, following the same row instructions. Once you have completed the decreases and have 44 (50, 52, 58, 60, 66) stitches, work even until the armhole measures 5 (5.5, 6, 6, 6.5, 6.5) inches. Now you are ready to shape the front neckline.

Front Neckline Shaping

With the RS facing, hdc across the first 14 (16, 17, 19, 20, 22) stitches. Chain 2 and turn. This is your right shoulder section. Work even on these stitches only for 3 (3, 3, 3, 3, 3) more rows. Fasten off.

Return to your remaining stitches. Skip the center 16 (18, 18, 20, 20, 22) stitches for the neckline opening and join your yarn to the 15th (17th, 18th, 20th, 21st, 23rd) stitch from the edge. Chain 2, hdc across to the end. Chain 2 and turn. This is your left shoulder section. Work even for 3 (3, 3, 3, 3, 3) more rows. Fasten off.

Assembling the Vest

Now that you have both panels finished, it is time to sew them together. Lay both pieces flat on a clean surface with the right sides facing each other.

Using your yarn needle and a length of matching yarn, seam the shoulders together. You will be joining the top 14 (16, 17, 19, 20, 22) stitches on each side of the back panel to the corresponding 14 (16, 17, 19, 20, 22) stitches on each shoulder of the front panel. A mattress stitch seam works beautifully here and creates an almost invisible join. A simple whipstitch seam also works well and is faster.

Once your shoulder seams are sewn, join the side seams. Starting at the bottom hem, seam up the sides, stopping at the armhole opening. The length of your side seam should be approximately 13 (13.5, 14, 14, 14.5, 14.5) inches — the full length of your lower body section. Leave everything above that open for the armholes.

Turn your vest right side out and try it on at this point if possible. This is the best moment to catch any fit issues before you add the border.

Adding the Border

The border is what gives the Coco Vest its clean, polished finish. You will be working a single crochet border all the way around the front and bottom opening, and a separate simple edging around each armhole.

Front and Bottom Border

Join your yarn at one of the bottom corners of the front panel. Working with the RS facing, sc evenly around the entire front and bottom opening. Along the bottom, you will work one sc per stitch. Along the front vertical edges, you will work approximately one sc per row, adjusting slightly to keep the edge from pulling or flaring. Work 3 sc into each bottom corner to help the edge lie flat. At the neckline, work one sc per stitch around the curve.

When you have worked all the way around, join with a sl st to the first sc. Work one more round of sc if you want a slightly more substantial border. Fasten off and weave in the end.

Armhole Border

Join your yarn at the underarm point of one armhole. Work sc evenly around the entire armhole opening, working one sc per stitch across the bound-off stitches at the top and one sc per row along the vertical sections. Join with a sl st. Work a second round if desired. Fasten off. Repeat for the second armhole.

Weave in all remaining ends using your yarn needle. Give your vest a gentle wet block by hand washing it carefully, pressing out excess water with a towel, and laying it flat to dry in the correct dimensions. Blocking will even out any uneven tension and help the vest drape beautifully.

Styling the Coco Vest

Part of what makes this vest such a useful piece is how easily it adapts to different looks. Here are a few ways to style it once it is finished.

For the most casual everyday look, wear the Coco Vest open over a striped or plain fitted t-shirt with your favorite jeans and a pair of sneakers or sandals. The open front creates a relaxed, effortlessly layered effect without any effort at all.

If you want something slightly more put-together, layer the vest over a silk or satin camisole and pair it with wide-leg trousers and flat mules. This works especially well in neutral colors like cream, camel, or soft grey, where the vest reads almost like a relaxed blazer alternative.

In cooler weather, the Coco Vest layers beautifully over a long-sleeve fitted top or a lightweight turtleneck. The generous armholes and relaxed shoulders mean it sits comfortably over thicker fabrics without bunching or pulling.

For a more boho or artisan aesthetic, try it in a warm earthy tone like terracotta, rust, or olive. These colors photograph beautifully and work well across multiple seasons.

Tips for a Perfect Finished Vest

A few final thoughts to help your project go smoothly from start to finish.

Swatch seriously. It takes an extra twenty minutes and it can save you from making an entire vest in the wrong size. Measure your gauge swatch after washing it, since many yarns will relax and grow slightly once they are wet.

Count your stitches regularly, especially during the decrease rows for the armhole shaping. It is easy to lose track during shaping, and catching an error after a few rows is much easier than catching it after ten.

If you find the chain-2 at the beginning of your hdc rows creates a gap you do not like, try chaining just 1 instead. This tightens the edge and can give a cleaner look, though it requires adjusting your turning technique slightly.

Do not be afraid to adjust the body length before you begin the armhole shaping. If you are tall, work the lower body section for a few extra rows. If you are petite, work a few fewer. The armhole and shoulder measurements are the ones that really need to stay consistent for proper fit.

Finally, if this is your first garment project, be patient with yourself during the seaming process. A well-seamed vest looks truly beautiful and professional, and it is worth taking the time to do it neatly.

Final Thoughts

The Coco Vest is a pattern that rewards you long after the last stitch is woven in. Every time you pull it on over a simple outfit and suddenly feel more put-together without really trying, you will remember why you made it. That is the real magic of handmade garments — not just the process, but the way the finished piece becomes a genuine part of your life.

Whether you make it in a crisp off-white cotton for summer, a warm rust tone for autumn, or a deep navy for year-round wear, this vest is going to earn its place in your wardrobe. Share your finished Coco Vest using the hashtag so others can find inspiration from your color choices and styling. And most importantly, enjoy every single row of the process.

Happy crocheting.
