The oversized, relaxed fit gives it that effortlessly cool look, and it’s one of those crochet sweater vest ideas that works just as well styled loose over jeans as it does tucked into trousers. Simple enough for an advancing beginner, with a finish that looks anything but. Fall wardrobe sorted, tap through for the free pattern.
A sweater vest is one of those layering pieces that looks intentional over almost anything, and this one works up so quickly the tutorial is titled a one-day project. The same dense knit-look rib that makes it feel substantial also makes it beginner-friendly because the stitch repeat never changes, which is the same quality that makes this slouchy sweater such a popular make. Two flat panels seamed at the shoulder and sides is all the construction there is.
Crochet Slouchy Sweater Vest
The mock turtleneck neckline is worked directly onto the body once the panels are joined so there is no separate piece to attach. It layers cleanly over a fitted long-sleeve shirt the way the finished photos show and the boxy proportions mean one size works across a wide range of fits.
Materials
- Paintbox Yarns Simply Aran (100% acrylic, 100 grams / 184 meters per skein)
- A 10 mm crochet hook
- Stitch markers
- Tapestry needle
The panels are worked side-to-side, and every stitch after the first row is worked in the back loop only to create the ribbing. The one stitch to know is the closed half double crochet: yarn over, insert your hook, yarn over and pull up a loop, then immediately pull that same loop through both remaining loops on your hook — a tidy, dense stitch that keeps the ribs crisp.
Basic Stitch to Know
The Pattern
Back Panel
- Foundation: Chain 65.
- Row 1: Skip the first chain from the hook. Work 7 slip stitches across the next 7 chains (place a stitch marker on the last slip stitch to track your ribbing border). Then work 57 closed half double crochet to the end of the chain. This gives 64 stitches total.
- Row 2 (back loop only): Chain 1 and turn. Skip the first stitch. Work 57 closed half double crochet in the back loop only until you reach your marker, then work 7 slip stitches in the back loop only to the end of the row.
- Row 3 (back loop only): Chain 1 and turn. Skip the first stitch. Work 7 slip stitches in the back loop only, then work 57 closed half double crochet in the back loop only to the end.
- Rows 4–56: Repeat the Row 2 and Row 3 pattern until you have completed 56 rows total, which creates 29 visible ribbing ridges. Tie off.
Front Panel
Shoulder Part 1 (Rows 1–18)
- Chain 65 and repeat the exact pattern as the back panel for 18 rows total (9 ribbing ridges). Make sure your 18th row ends at the slip-stitch (bottom waist) side.

Neckline Decreases (Rows 19–30)
- Row 19: Work 7 slip stitches in the back loop only, then work 56 closed half double crochet in the back loop only, leaving the very last stitch unworked at the top neck edge to decrease by 1.
- Row 20: Chain 1 and turn. Work 56 closed half double crochet in the back loop only, then 7 slip stitches in the back loop only.
- Rows 21–30: Repeat this decrease rhythm 5 more times, decreasing 1 stitch every 2 rows at the neck side. You will end with 30 total rows.
Neckline Increases (Rows 31–42)
- Row 31: Work 7 slip stitches in the back loop only, then work 51 closed half double crochet in the back loop only to the neck edge. At the very end of the row, chain 2 and turn.
- Row 32: Skip the first chain from your hook and work 1 closed half double crochet into the second chain (this creates your increase). Continue with closed half double crochet in the back loop only (52 total) across, ending with 7 slip stitches in the back loop only.
- Rows 33–42: Repeat this increasing rhythm 5 more times until your stitch count climbs back up to 57 closed half double crochet and 7 slip stitches, mirroring the neck cutout.
Shoulder Part 2 (Rows 43–59)
- Repeat the standard row instructions with no more shaping for 16 more rows. Add 1 final layout row to bring the working tail to the top-right corner, finishing with 59 rows total for the front panel.
Assembly and Side Sewing
- Lay your back panel down, then lay the front panel directly on top of it, making sure the foundation chain sides align correctly.
- Using a tapestry needle and yarn, sew across the two top shoulder seams.
- Sew up the side seams from the waist ribbing upward, leaving an adequately sized opening at the top of each side for the armholes.
High Neck Collar
- Find the middle ribbing ridge on the back neckline and insert your hook into the last “V” loop of that ridge.
- Base chain: Chain 12, plus 1 turning chain (13 total).
- Row 1: Skip the first chain and work 12 slip stitches back down toward the vest body.
- Anchor: Anchor your collar row to the neck opening by slip-stitching into the gap right between the next two panel ridges.
- Row 2 (back loop only): Turn your work. Skip the anchor loop you just made, and work 12 slip stitches in the back loop only outward to the edge of the collar.
- Row 3 (back loop only): Chain 1 and turn. Work 12 slip stitches in the back loop only back inward toward the body, then anchor into the next ridge loop on the collar line.
- Repeat: Keep working back and forth in back-loop-only slip stitch all the way around the neck opening. Cut the yarn leaving a long tail, sew the two short ends of the collar together, fold the collar over in half, and sew the raw edge down to clean up the neckline inside.
Shaping the Structured Shoulders
This gives the padded-shoulder look without any foam inserts.
- Turn the garment inside out.
- At the very top of the armhole seam, fold the shoulder edge inward by roughly 5 centimeters (about 3 ribbing ridges deep).
- Taper this fold gradually down toward the bottom of the armhole so it transitions smoothly into zero fold near the armpit.
- Using a tapestry needle and a loose whip stitch, secure the folded fabric flaps inside.
- Once both shoulders are folded and lightly sewn, flip your vest right-side out to reveal the structured silhouette.
A Few Tips
- Count ridges, not just rows. The pattern gives you ridge counts at every stage, so if you lose your place mid-row, count the visible ribs to check your progress.
- Keep the foundation chain relaxed. On a 10 mm hook, a tight starting chain pulls the whole edge in — chain loosely so the panels lie flat.
- Go light on the shoulder fold stitches. The structured shoulders should hold their shape but still feel soft, so secure the folds with a loose whip stitch rather than pulling them tight.
Frequently Asked Questions
1. Can I really finish this in a day? With the chunky 10 mm hook and simple repeated rows, it works up fast, so a focused day is realistic for many crocheters. Your own pace and the shaping rows will decide how close you get.
2. What makes the shoulders look structured without padding? You fold and tack the top of each shoulder inward, tapering the fold toward the armpit. That folded fabric props the shoulder line up, creating the padded look with yarn alone.
3. How do I size it up or down? The panel width comes from your foundation chain length and the body width from the number of rows. Add rows for a wider fit or remove them for a closer one, keeping the front and back panels matched.
