Picture this: you spot a stunning crocheted dress in a beach shop, check the price tag, and nearly choke. Two hundred bucks for something your hook could create better. That exact moment sparked this navy blue coastal granny square dress. Those bold aqua and navy squares against creamy yarn look like Mediterranean tiles meeting ocean waves. Ready to make your own statement piece that screams boutique without the crazy cost?
Why This Granny Square Dress Steals the Show
This design breaks a big project into bite-sized wins. You crochet individual granny squares first. They travel well in your bag and give quick satisfaction. Then you join them into panels and build the body around them. No overwhelm, just steady progress.
The A-line shape skims your hips and drops to mid-thigh. It flatters most figures and moves with you. Three-quarter sleeves with drawstring ties at the cuffs add that romantic touch without extra fuss.
I sized this for Small/Medium (US 4 to 10). Later tips help you tweak the fit if needed. Want a dress that looks high-end resort ready? This delivers.

Skill Level and Realistic Time Commitment
Call this Advanced Beginner to Intermediate. The granny squares stick to basic stitches: chain, slip stitch, double crochet, single crochet. If you already make granny squares, you own the core skill.
Joining motifs cleanly, shaping with increases, and setting in sleeves bring the challenge. Finished one crochet garment before? You will handle this fine.
Plan on 40 to 60 hours total. Squares take 12 to 16 hours. Body construction adds 18 to 24 hours. Finishing, seaming, and details need 6 to 10 more. This is a labor of love, not a weekend sprint. Grab your favorite podcast and settle in.
Finished Measurements
Bust: 36 inches / 91.5 cm
Waist: 32 inches / 81 cm
Hip: 40 inches / 101.5 cm
Total length from shoulder to hem: 32 inches / 81 cm
Sleeve length from underarm to cuff: 12 inches / 30.5 cm
These numbers give a flattering mid-thigh A-line. Measure yourself and compare before you start.
Materials You Need for Success
Grab worsted weight yarn (CYCA 4) in five colors:
- Color A (off-white/cream): about 1,400 yards / 1,280 meters
- Color B (navy blue): about 300 yards / 274 meters
- Color C (medium aqua/turquoise): about 200 yards / 183 meters
- Color D (light aqua/sky): about 150 yards / 137 meters
- Color E (teal/blue-green): about 100 yards / 91 meters
Good yarn options include smooth worsted acrylics or cotton blends that show stitch definition. Machine-washable choices keep life easy. Skip fuzzy or novelty yarns – they hide the pretty granny pattern.
Hook: US size J / 6.0 mm for squares and body. Optional US size I / 5.5 mm for tighter edging.
Notions:
Yarn needle
At least 8 stitch markers
Scissors
12 to 14 pearl-style shank buttons, 5/8 inch / 16 mm
Sewing needle and matching thread for Color A
Two pieces of coordinating ribbon or twisted cord, each 18 inches / 46 cm, for sleeve ties
Blocking mats and pins
Spray bottle or basin for wet blocking
Gauge – Do Not Skip This
With US size J / 6.0 mm hook:
14 sc x 16 rows = 4 inches / 10 cm in single crochet, blocked.
One completed granny square (after Round 5) = 5.5 inches / 14 cm x 5.5 inches / 14 cm, blocked.
Gauge decides everything on garments. Half a stitch off per inch ruins the fit. Swatch, block, measure, adjust hook if needed.

Key Pattern Notes Before You Start
- The dress front works flat in two panels. The back works flat too. Join all three at the side seams.
- Make all 10 granny squares first, join them, then build the body.
- Color sequence for each square: Rounds 1 and 2 in Color E (teal). Round 3 in Color C (medium aqua). Round 4 in Color D (light aqua). Round 5 in Color B (navy blue). Round 6 in Color A (off-white).
- For single crochet sections, ch 1 at the beginning of each row does NOT count as a stitch.
- For double crochet sections, ch 3 counts as the first dc.
