Can I make this vest bigger or smaller than the example?

Yes, the whole pattern is built from your own bust, hip, or stomach measurement divided by two for the back piece. The front panels and all the shaping scale from that same number, so the proportions stay correct at any size.

Why does the pattern use two different hook sizes?

The 5.5 mm hook is used just for the starting chain, which keeps that foundation row loose enough to work into easily. The 4.5 mm hook works the rest of the fabric a bit tighter, giving the vest more structure and drape.

How do I know which side of the front panel to mark for decreases?

Mark the side of each front panel that will sit at the armhole before you start the shaping rows. That marker keeps your decreases on the correct edge through all the rows, especially since you're making two panels that mirror each other.

Do I need to add a closure to this vest?

No, the closure with beads or a small button is listed as optional in the materials. The vest is designed to be worn open as a layering piece, so you can skip the closure entirely if you prefer that look.

What's the best way to check my panels will fit together before finishing?

Align both front panels over the back piece before you work the edging, matching them up at the shoulders and armholes. This lets you confirm the fit and spacing while you can still adjust, rather than after the shell stitch edging is in place.

About This Pattern

This one has an easy, open feel to it, like a cardigan that decided to be casual about buttons. Three simple panels come together into something you'd actually reach for on a cool evening. It reads polished without trying too hard, which is exactly the vibe I'm after.

Your hands get a nice mix here: steady rows of alternating single and double crochet, then the focus work of shaping the armholes and neckline. You'll measure yourself before you even pick up the hook, which makes the whole thing feel personal. Then it's rhythm, decrease, rhythm, decrease, until the shoulders line up.

Draped over a chair or worn over a tank top, this vest has presence without shouting. The shell stitch edging catches the light and gives it a finished, boutique look. It's the kind of piece that makes a plain room, or a plain outfit, feel considered.

Measure your widest part first, then divide by two to set the width for the back piece.
Build the back piece in alternating single crochet and double crochet until it reaches just below the armpit.
Shape the back armholes with a short run of decrease rows, then work straight again toward the shoulder.
Chain and work each front panel using the back chain count to figure its width, mirroring the pair.
Shape the armhole and neckline on each front panel, marking the armhole side so decreases land correctly.
Align the two front panels over the back piece to check the fit, then sew the shoulder and side seams.
Finish by working the shell stitch edging around the outer edges, the back neckline, and each armhole, then weave in ends.
Add the optional beaded cord closure at the neckline if you want a way to cinch the vest closed.

Three-panel crochet bolero vest with shell edging

Easy to get wrong

Losing the sc/dc alternation

Keep checking that you're placing sc over dc and dc over sc as you go, since one missed row throws off the texture for the rest of the piece. Lay the work flat every few rows to spot-check the pattern.

Front panel width miscalculated

Double-check that each front panel chain equals half your back chain count plus 4 before you start the first row. Recount rather than estimate, since this sets the whole fit.

Shell edging spacing drifts

Keep the 3 sc, skip, slip stitch rhythm consistent, especially around the curved neckline where spacing naturally wants to shift. Pause at the curve and adjust gaps slightly so the edge lies flat instead of rippling.

Between the songs

What I love about this vest is how the alternating single crochet and double crochet rows build a subtle basketweave texture without any fancy stitch names to memorize. You just place sc over dc and dc over sc, row after row, and the fabric does the rest. The armhole and neckline shaping on the front panels is where it gets interesting, decreasing on the marked side while keeping the fabric even. Then the shell stitch edging, that rhythm of 3 sc, skip, slip stitch, ties the whole piece together and turns raw edges into a clean, finished line. It's a project that rewards paying attention without demanding perfection.
