Why You’ll Love This Granny Square Vest Pattern
Granny squares have had a massive comeback in recent years, and it’s easy to see why. They’re satisfying to make, endlessly customizable, and work up quickly in smaller sizes. Using them to build a garment is a brilliant approach for beginners because you’re not working one giant piece of fabric — you’re working small, manageable motifs and assembling them like a puzzle.
A vest is also one of the most forgiving garments to crochet. Because it doesn’t have sleeves and doesn’t need to fit perfectly around the arms, there’s a lot more room to play with sizing. A slightly larger or smaller finished vest still looks intentional and stylish. This makes the pattern forgiving for beginners who are still getting comfortable with gauge and tension.
The boho aesthetic of this design also means that a relaxed, airy fit looks completely intentional. Worn over a flowy white dress, a crochet bralette, a simple tank top, or even a bikini at the beach, this vest instantly elevates any look. It’s one of those pieces that photographs beautifully and earns compliments every time you wear it.
Materials You’ll Need
Before you start, gather your supplies. Because this is a summer top, you want a yarn that’s lightweight, breathable, and comfortable against the skin.
Yarn: For the best results, choose a cotton or cotton-blend yarn in a DK or worsted weight. Cotton is perfect for summer wear because it’s cool, holds its shape well, and has a lovely drape when crocheted at a slightly looser gauge. You’ll need approximately 400–600 yards depending on your chosen size. Popular yarn choices for this type of project include Paintbox Simply Cotton Worsted, Lion Brand 24/7 Cotton, Paintbox Simply DK, or any budget-friendly cotton from your local craft store.
Hook: A 5mm (H/8) crochet hook works well for most worsted weight cotton yarns. If you’re using a DK weight, try a 4mm (G/6) hook. Always check your gauge before starting.
Additional supplies: A yarn needle for weaving in ends and joining squares, scissors, stitch markers (optional but helpful), and a measuring tape.
Gauge
Gauge matters for garments, but this pattern is more flexible than most because the vest is assembled from individual squares. Make a test square and measure it. Your finished square should measure approximately 4 inches by 4 inches using worsted weight cotton on a 5mm hook. If your square is larger, go down a hook size. If it’s smaller, go up a hook size.
Don’t stress too much about this. The beauty of a square-constructed garment is that your finished measurements will simply reflect the size of your squares. Once you know your square size, you can plan your layout accordingly.
Sizing
This pattern works in a range of sizes. The vest is constructed using a grid of granny squares arranged across the front and back panels. Here is a basic sizing guide based on 4-inch squares:
For a Small/Medium (finished bust 32–38 inches), you’ll work 4 squares across each panel and 5 rows tall, for a total of 40 squares across the entire vest.
For a Medium/Large (finished bust 38–44 inches), you’ll work 5 squares across each panel and 5 rows tall, for a total of 50 squares.
For a Large/XL (finished bust 44–50 inches), you’ll work 5 squares across each panel and 6 rows tall, for a total of 60 squares.
These are approximate guides. Measure yourself and plan your layout before you begin, keeping in mind that the vest has an open front and is meant to hang loosely rather than fit snugly.
The Granny Square Pattern
This is a classic three-round granny square with a simple, open design that works up quickly and creates a lovely lacy texture ideal for warm weather.
Foundation ring: Make a magic ring or chain 4 and join with a slip stitch to form a ring.
Round 1: Chain 3 (counts as first double crochet throughout), work 2 double crochets into the ring, chain 2, (3 double crochets into ring, chain 2) three more times, join with a slip stitch to the top of the beginning chain 3. You will have four clusters of 3 double crochets separated by chain-2 corner spaces.
Round 2: Slip stitch into the next 2 stitches and into the chain-2 corner space. Chain 3, work 2 double crochets into the same corner space, chain 2, 3 double crochets into the same corner space (this creates your first corner). Chain 1, then work (3 double crochets, chain 2, 3 double crochets) into the next corner space, chain 1. Repeat from the asterisk around. Join with a slip stitch to the top of the beginning chain 3.
Round 3: Slip stitch into the next 2 stitches and into the corner space. Chain 3, work 2 double crochets into the same corner space, chain 2, 3 double crochets into the same corner space. Chain 1, work 3 double crochets into the chain-1 side space, chain 1, then work (3 double crochets, chain 2, 3 double crochets) into the next corner space. Repeat from the beginning of the round. Join with a slip stitch and fasten off.
Weave in your ends. Your square is complete.
For a single-color vest, make all of your squares in the same yarn. For a more vibrant boho look, experiment with different colors. You can do one color per round, change colors each square, or create a gradient effect by slowly shifting between shades of the same color family.
Color Palette Ideas
One of the most fun parts of this project is choosing your color palette. Since the design is boho, you have a lot of latitude to be creative and expressive.
A natural, earthy palette uses warm cream, terracotta, sage green, and dusty blush. This combination feels grounded and organic, and it photographs beautifully in natural light settings.
A bold and vibrant palette uses cobalt blue, sunshine yellow, hot pink, and turquoise for a true boho festival look. Think summer concert, beachside market stall, or warm vacation evenings.
A coastal palette uses navy, sand, sky blue, and white. This feels effortlessly chic and works well if you tend toward a more minimal wardrobe.
A monochromatic palette in shades of the same hue — like dusty rose, blush, mauve, and cream — gives the vest a sophisticated, modern look that works well for adults who love crochet but prefer something slightly more understated.
How to Assemble the Vest
This is where the magic happens. Once you’ve made all of your squares, you’ll join them into two panels — one front panel and one back panel — and then seam the shoulders and sides to create the vest shape.
Joining the squares: The flat slip stitch join is the most beginner-friendly method. With right sides together, use a slip stitch through the back loops of both edges to join your squares in rows, then join those rows together into panels. This creates a subtle, textured seam on the wrong side.
If you prefer a more decorative join, the join-as-you-go method or a flat single crochet join on the right side creates a visible ridge that adds to the boho texture of the finished piece. Many makers love this look.
Arranging the panels: Lay your squares out on a flat surface before joining to make sure you’re happy with the color placement. Take a photo so you can reference it as you work. There’s nothing more frustrating than getting halfway through joining and realizing you want to switch two squares around.
Front panel: For an open-front vest, the two front panels can be two separate narrow strips joined only at the shoulder and left open at the center. Alternatively, you can make the front panel the same width as the back and leave the front edges unjoined, letting the vest hang open naturally.
Shoulder seams: Join the top edge of the front panel to the top edge of the back panel at the shoulders. Leave enough space in the center for the neck opening. A good rule of thumb is to leave the center third of the top edge open for the neck.
Side seams: Join the front and back panels at the side edges, leaving the top portion open for the armhole. How much you leave open depends on your preference and measurement. A minimum of 6–8 inches (or 1.5 to 2 squares) of open space creates a comfortable armhole for most people.
Finishing the Edges
A beautiful border makes a huge difference in the polished appearance of a finished garment. For this vest, a simple single crochet border worked around all edges (neck, armholes, front opening, and hem) creates a clean, defined look.
Work one or two rounds of single crochet evenly around each edge, working three single crochets into each corner to keep the edges flat. If you want a lacier border, add a shell stitch or a picot edging on the final round. A round of reverse single crochet (also called crab stitch) gives the edges a beautiful, professional-looking cord-like finish that is surprisingly easy once you get the hang of the backwards motion.
You can also add fringe to the hem for an extra boho touch. Cut lengths of yarn twice the desired fringe length, fold them in half, and use a crochet hook to pull the folded loop through the bottom edge of the vest, then draw the ends through the loop and pull snug. Trim to an even length once all fringe is attached.
Tips for Beginners
If this is your first garment project, here are a few tips to make the process smoother and more enjoyable.
Work your squares in batches. Making ten or twenty squares at a time before you start joining means you can work while watching television, listening to podcasts, or just enjoying a quiet evening. Squares are wonderfully portable and low-commitment.
Use stitch markers to mark your corner spaces on the first round of each square. This makes following along much easier when you’re just getting started with the pattern.
Block your finished squares before joining. Wet blocking cotton squares by soaking them in water, gently pressing out the excess moisture, and laying them flat to dry ensures that all your squares are exactly the same size and makes joining them a breeze. It also improves the drape and appearance of the finished fabric dramatically.
Keep a consistent tension. Tight tension is a common beginner habit. If your squares feel stiff, try loosening your grip and letting the yarn flow more freely through your fingers. Cotton can be less forgiving than wool because it has no stretch, so a slightly looser tension usually works better.
Join your squares with a slightly larger hook than you used to make them. This helps keep the seams from pulling and puckering.
Customizing Your Vest
One of the joys of this pattern is how easily it adapts to your personal style. Here are a few ways to make it your own.
Add a tie or ribbon at the front opening for a more defined silhouette. Thread a piece of leather cord, ribbon, or a crocheted chain through the squares at the waist level and tie it in a bow or knot in front.
Make it longer by adding extra rows of squares at the hem. A longer vest that hits at the hip or even the thigh has a completely different, more dramatic vibe than a cropped version.
Incorporate different square sizes. Using a mix of large squares for the main body and smaller squares or half squares to fill in edges can create a more complex, patchwork-style appearance.
Use different yarn fibers for different squares within the same vest. Mixing matte cotton with a slightly shiny bamboo or rayon blend adds subtle texture variation that looks intentional and interesting.
