Ocean Blues Alpine Tank Dress: Free Crochet Pattern
Introduction
The Ocean Blues Alpine Tank Dress is a beginner-friendly crochet dress that looks far more complicated than it is. Worked in the round from hem to underarm in textured alpine stitch, it forms a simple straight tube, then splits into flat front and back panels with thin straps for a Y2K tank silhouette. Horizontal stripes in light, medium, and dark blue flow up the body like ocean waves, and the raised alpine texture gives the fabric a soft, squishy, store-bought feel. Because there is no waist shaping, the length is easy to customize, making this a wonderful first dress project for anyone comfortable with single and double crochet.

Gauge
16 stitches and 12 rows = 4 inches (10 cm) in alpine stitch pattern. Work a small swatch in pattern and measure a 4-inch section; adjust your hook size if your stitch count differs.
Tips Before You Start
- Count your stitches after every single crochet row; the alpine pattern depends on keeping 128 stitches around the body.
- Change colors at the end of the last stitch of a row so the stripe edge stays clean.
- Try the tube on as you go; because there is no shaping, length is the only thing to adjust.
- Keep your tension relaxed so the textured fabric drapes rather than stiffens.
Step-by-Step Instructions
Body (worked in the round from hem to underarm)
With A, ch 128, join with sl st to first ch to form a ring, being careful not to twist.
R1: Ch 1, sc in each ch around, join with sl st to first sc (128 sc).
R2: Ch 2 (counts as first dc), dc in next st, *[dc, ch 1, dc] in next st, skip next st; rep from * around, join with sl st to top of ch-2 (64 groups of [dc, ch 1, dc]).
R3: Ch 1, sc in each dc and ch-1 sp around, join with sl st to first sc (128 sc).
R4: Ch 2, dc in next st, *[dc, ch 1, dc] in next sc, skip next sc; rep from * around, join with sl st to top of ch-2 (64 groups).
Repeat R3–R4 for pattern. Work stripes as follows: 6 rows A, 6 rows B, 6 rows C, then repeat the stripe sequence. Continue until the piece measures 22 inches (56 cm) from the hem, ending after a R3 (sc row). Fasten off.
Divide for Front and Back
With right side facing, count 64 sts for the front and 64 sts for the back. Mark the underarm sts.
Front
Join yarn at the first st of the front. Work in alpine stitch pattern (R4 and R3 alternately) across 64 sts for 16 rows, ending after a R3. Fasten off.
Back
Join yarn at the first st of the back. Work the same as the front for 16 rows, ending after a R3. Fasten off.
Straps (make 2)
With A, ch 4.
Row 1: Sc in 2nd ch from hook and in each ch across (3 sc).
Row 2: Ch 1, turn, sc in each sc across (3 sc).
Repeat Row 2 until the strap measures 10 inches (25 cm). Fasten off.
Armhole Edging
With A, join yarn at the underarm, ch 1, sc evenly around the armhole, join with sl st. Repeat for the other armhole.
Assembly and Finishing
Sew the straps to the front and back at the shoulders, positioning them 4 inches (10 cm) from the side edges. Sew side seams from underarm to hem if desired for a closer fit (optional). Weave in all ends. Block gently to open the alpine texture and even out the stripes, then lay flat to dry.
Pro Tips and Variations
- Make it a midi or maxi by adding more stripe repeats before the underarm split.
- Swap the three blues for a single color for a minimalist look, or use a self-striping yarn.
- Add a few sc rows to the neckline or widen the straps to 5 sts for extra coverage.
