Vests are the smart shortcut into garment crochet. No sleeves means no set-in shaping, no seaming rounds, no ten hours of stockinette down each arm — just two panels and a bit of finishing. This loose crochet sweater vest layers over a shirt, a tee, or nothing at all, and the relaxed fit means your gauge doesn’t have to be perfect to wear it. Free pattern’s below if you’ve been putting off making clothes.
Sage green and cream alternate row by row to build the houndstooth texture on this sweater vest, giving it a polished two-color look that reads far more complex than it actually is. If you enjoy colorwork vests, the free crochet slouchy sweater vest pattern is another structured layering piece worth adding to your queue.
Loose Crochet Sweater Vest
Front and back panels are worked flat in the houndstooth stitch, then seamed at the shoulders and sides with a solid green ribbed band added along the hem and V-neckline to frame the colorwork cleanly. The relaxed length hits at the hip, making it easy to layer over shirts or fitted tops through the season.
Why I love this one: the houndstooth pattern is built entirely from alternating single and double crochets — two stitches you already know — and yet the result looks intricate and intentional every time.
Materials and Tools
- Medium-weight yarn in two contrasting colors — green and off-white or cream
- A 5.5 mm crochet hook
- Measuring tape
- Scissors
- Tapestry needle
Common Stitch to Know
Difficulty and Time
This is an easy-to-intermediate project. The stitch work is simple — single crochet and double crochet alternating across the row — but the color-switching rhythm (every 2 rows) and the dual shaping of the armholes and V-neck take a little concentration. Everything is worked flat, and the body panels build steadily once you’re into the houndstooth repeat. Allow yourself a relaxed few sessions and it comes together comfortably.
The Pattern
The vest begins with a horizontal ribbed border in green, then turns to build the body upward in the houndstooth two-color pattern, with armhole shaping and a V-neck added at the upper chest. The shoulder seams are joined at the end.
1. Bottom Ribbing Border
The bottom ribbing is made horizontally with the green yarn, using back-loop-only stitches to create a stretchy ridged band.
- Foundation chain: Start with a slip knot in green yarn and chain 12.
- Row 1 (front loops only): Turn and insert your hook only into the front loops of the chain. Work a single crochet into each loop across. (11 single crochet total.)
- Row 2 onwards (back loops only): Chain 1 and turn your work. Insert your hook only into the back loops of the stitches and work a half double crochet into each back loop across.
- Length adjustment: Repeat Row 2 until the ribbed border strip stretches to a width of 56 cm, or until it matches your body circumference measurement. If you crochet slightly too much, simply undo rows until it hits your target.

2. The Houndstooth Body Section
The houndstooth effect comes from alternating single crochet and double crochet across every row, while switching between two colors every two rows.
- Transition row: Once the ribbing reaches your target measurement, turn your work horizontally so you’re crocheting along the long edge of the ribbed border. Attach your yarn and stitch evenly across the top side edge to establish the base row for the body panel.
- The stitch sequence: Work across every row alternating 1 single crochet, then 1 double crochet, all the way across the row.
- Color-switching rule: Work 2 rows in green, then 2 rows in off-white. Keep swapping colors after every two rows, carrying the yarn upward along the side edge or cutting and weaving in ends as you prefer.
- Panel growth: Follow this consistent alternating-color pattern, building the body panel upward, until you reach the underarm level where the armhole shaping begins.
3. Armhole and V-Neck Shaping
- Armhole cutouts: Once at the underarm height, decrease or leave a specific number of stitches unworked at both the left and right outer edges to create the flat vertical recesses for the arm openings.
- V-neck front slit: At the same time, split your row work directly down the exact middle of the front panel to begin shaping the V-neck.
- Decreasing for the shoulders: Work each side of the upper chest independently. Gradually decrease 1 stitch along the neck-facing edge every few rows to create an angled slope inward. Continue until the remaining stitches form a flat shoulder band. Repeat the same process symmetrically on the opposite side.
- Sew the shoulder seams together to close the top of the vest, matching the bands neatly across the back.
Tips and Troubleshooting
- Measure your ribbing against your body. The 56 cm target is a medium-sized guide — hold the growing strip around your torso as you work and stop when it fits, not when you hit an exact row count.
- Carry your yarn up the side rather than cutting. With a two-row color swap, you can easily carry the unused yarn up the edge by twisting it around the working yarn at the turn. This saves dozens of ends to weave in.
- Keep the alternating stitch pattern consistent. In the houndstooth section, the single crochet and double crochet should alternate on every row in the same order. If a row starts with a single crochet, the next should also start with a single crochet — shifting this breaks the houndstooth alignment.
Customization Ideas
- Change the color palette. The houndstooth effect works in any two contrasting colors — navy and cream, rust and black, or even two tones of the same color for a subtle tonal effect.
- Make it longer. Add more body rows before starting the armhole shaping to take it from a standard vest length to a longline version.
- Skip the V-neck. Working straight across the top and leaving a wider neck opening gives a simple crew-neck or boat-neck silhouette instead.
- Adjust the width. Work more or fewer ribbing rows before the transition to widen or narrow the vest to suit your measurements.
Frequently Asked Questions
1. How does alternating single and double crochet create a houndstooth look? The height difference between single crochet and double crochet in each stitch position, combined with the two-row color swap, creates diagonal flecks that optically read as the classic houndstooth diamond pattern when worked consistently. The effect becomes clearer as the panel grows — trust the process through the first few color repeats.
2. Can I use a different yarn weight? Yes, though you’ll need to adjust the hook accordingly and re-measure the ribbing to your own body circumference rather than relying on the 56 cm measurement. A DK weight on a smaller hook gives a finer, more drape-forward vest; a bulkier yarn makes a chunkier, warmer one.
3. The source doesn’t give specific stitch counts for the armhole or V-neck shaping — how do I manage that? Because this pattern is built to your own measurements, the armhole and V-neck shapes are sized by how far you’ve grown the panel and how it lines up with your body. Work the armhole by leaving stitches unworked at the outer edges to match your arm opening measurement, then split the center and decrease toward the neck edge gradually until each shoulder reaches the width you need. Watching the original video for the visual guidance on these sections is recommended.
4. Should I cut the yarn or carry it when switching colors? Carrying it up the side (by twisting it around the working yarn at each turn) is much cleaner with a two-row swap — you’ll change colors frequently enough that cutting and rejoining creates a disproportionate number of ends to weave in. Carry it unless the float becomes too long or the edge starts to pull.
