Lacy Shell Pattern crochet vest — Step-by-Step Pattern

This pattern guides you through making a beautifully simple lacy shell crochet vest from start to finish. Constructed in two identical panels with a straightforward shell stitch motif, shaped armholes and neck, and neat straps, this garment is perfect for layering or summer wear. The finishing touch: dainty picot edging for a polished, feminine look.

Pattern Overview

Easy Construction: Two flat panels (front and back) are crocheted identically, then seamed.
Classic Shell Motif: Open lacework created using (2 dc, ch 1, 2 dc) shells separated by single dc for a breezy, elegant effect.
Clear Armhole & Neck Shaping: Gradual decreases for a well-fitting armhole and neckline.
Customizable Lengths: Adjust panel and strap length for a personalized fit.
Decorative Edging: Picot and single crochet edging along neck, arms, and hem for a finished, refined trim.

Notes

1. Foundation & Body Panel

Step 1: Make Foundation Chain

Ch 115. (This is the width and should measure approximately 41 cm or 16″.)

Step 2: Row 1 (WS) — Single Crochet Foundation

Ch 1 (does not count as a stitch), sc in each ch across. (115 sc)

Save

Step 5: Row 4 — First Shell Pattern Row

Ch 3, turn.
Dc in first st, skip next 2 sts.
(2 dc, ch 1, 2 dc) in next st (makes a shell), skip 2 sts, dc in next st; repeat from * to end of row.
At the end, your row should alternate between shells and single dc stitches across.

Rows 5–19: Continue Shell Pattern

Each row: Ch 3, turn.
(2 dc, ch 1, 2 dc) in ch-1 space of previous row’s shell, dc in next dc; repeat to end.

Save

2. Armhole & Neck Shaping (Rows 20–28)

Step 6: Begin Armhole Decreases

Row 20: Ch 3, turn.
Skip the first ch-1 space (first shell), continue shell pattern up to the last shell, skip last ch-1 space, dc in turning ch or last st at the end of row.
This removes one shell motif at each side, starting the curve of the armhole and neckline.

Rows 21–28: Continue Decreasing

Each row: Continue shell pattern, skipping an extra shell at both the beginning and end of each new row.
Repeat for a total of 8 decrease rows.
Your panel will now be narrower at the top for armholes and neck.

3. Straps (Make Two)

Step 7: Attach Straps at Shoulder Corners

At each top corner (shoulder area), attach yarn and ch 3.
Row 1: Dc in same place; (2 dc, ch 1, 2 dc) in next ch-1 space; repeat across strap width.
Work in this pattern for about 11 rows, or until the strap is 12 cm (4.7 in) long.
Fasten off.
Repeat for the other shoulder to make two straps.

4. Finishing Body & Edges

Step 8: Make Second Panel

Make a second identical panel following steps 1–7 for the back of your top.

Step 9: Join Panels

With right sides (RS) facing, align panels.
Use a yarn needle or sc/whip stitch to seam side edges from armhole (row 19) down to bottom hem.
Seam shoulder tops, joining strap ends.
Leave armholes and neck opening unseamed.
Save

Step 10: Work Edging Around Openings

Attach yarn at neck, armhole, or hem.
Work sc evenly around the opening of each armhole and neck for a neat finish.

Step 11: Picot Edging for Hems and Sides

Along bottom and side seams:
- Work 2 sc, ch 3, sl st into first ch (picot made), 3 sc, ch 3, sl st into first ch (repeat).
Continue this pattern all around.
Fasten off and securely weave in all ends.
