Ever wanted a crochet set that screams “I just stepped off a yacht” without the actual yacht price tag? This navy blue nautical ruffle set delivers exactly that vibe. Double-layered ruffles, wave-like chevron texture, crisp white picot edges, and those adorable anchor buttons turn a simple crop top and mini skirt into pure coastal drama. Let’s make it together.
A Stunning Two-Piece Coastal Ensemble You’ll Love Creating
This set pairs an off-the-shoulder crop top with cascading double ruffles and a high-waisted mini skirt that sports matching tiered ruffles. Both pieces share the same chevron ripple stitch so they look like they belong together. The white picot trim pops against the deep navy, and the corset-style lacing on the skirt waistband lets you tweak the fit on the fly.
I went hard on the ruffles because one layer never felt dramatic enough. The chevron pattern gives that gentle wave motion every time you walk. And those little gold anchor buttons? They seal the whole nautical deal.
About This Navy Blue Nautical Crochet Pattern
You work the crop top flat so the center front can open for buttons. The skirt starts as a ribbed waistband tube and grows downward in the round. Every ruffle gets picked up from an existing edge and built outward for that layered look.
The top features a stretchy ribbed underbust band, a short chevron body, and two ruffle tiers that create the off-the-shoulder effect. The skirt gives you a wide ribbed waistband with grommets for lacing plus two full ruffle tiers that move like water.
Everything stays coordinated because both pieces use the same stitch language and the same white picot finish. One pattern, two pieces, zero mismatch risk.
Skill Level
Advanced Beginner to Intermediate
You only need chains, single crochet, half double, and double crochet. The chevron pattern just asks you to pay attention to where the peaks and valleys land. Managing the double ruffles and the button opening adds a little extra focus, but nothing scary. Basic sewing skills handle the buttons and grommets.
If you have already finished a few garments and can follow a pattern without panic, you can handle this set.
Time Estimate
Plan on 18 to 25 hours total. The crop top usually takes 8–12 hours. The skirt takes 10–13 hours. Your actual time depends on how fast you crochet and how often you stop to admire the ruffles (no judgment).

Special Stitches Explained
Ripple Chevron Pattern
This creates the wave texture. It runs on a multiple of 12 stitches plus edge stitches. Each repeat works a valley decrease (dc2tog), four regular dc, a peak of 3 dc in one stitch, four more dc, then the next valley. Keep peaks stacked over peaks and valleys over valleys. The fabric instantly looks like little ocean waves.
Picot Edging
Join the white yarn with a slip stitch. Work sc, sc, sc, then chain 3 and slip stitch into the first of those three chains to form a tiny loop. Repeat the three sc plus picot all the way across. The picots sit every three stitches and give that clean scalloped finish.
Back Loop Ribbing
Work every single crochet through the back loop only. The ridges form automatically and the fabric gains stretch. Perfect for both the crop top band and the skirt waistband.
Important Pattern Notes Before You Begin
- The crop top works flat so the center front stays open for buttons. Side seams come later.
- The skirt works in the round from the waistband down.
- Every ruffle starts by picking up stitches along an existing edge.
- Turning chains for double crochet count as one stitch.
- For a tighter fit, drop one full 12-stitch repeat. For more ease, add one. Adjust yarn amounts.
- Block both pieces before you add buttons or grommets. The chevron opens up beautifully.
- Reinforce the grommet spots with stabilizer on the wrong side so the fabric does not tear.
- Keep the picot tension relaxed or the edge will curl. Block it flat afterward.
Crop Top Instructions
Section 1: Bottom Ribbed Band
With E-4 hook and navy, chain 13.
Row 1 (WS): Sc in second chain from hook and across. Turn. 12 sc.
Row 2 (RS): Ch 1, sc in BLO of every stitch. Turn.
Repeat Row 2 until the strip measures 32 inches. Fold the short ends together with right sides out and slip stitch them closed into a tube. The seam sits at the left side.
Your band should feel snug around the underbust and stand about 2.5 inches tall.

Section 2: Crop Top Body (Chevron Main Panel)
Chain 146 with the E-4 hook and navy.
Foundation row: Dc in fourth chain from hook (the skipped chains count as the first dc). Continue the chevron: dc2tog, 4 dc, 3 dc in next stitch (peak), 4 dc, and repeat across. End with two regular dc. Turn. You now have 144 working stitches (12 full repeats).
Rows 2–12: Ch 3 (counts as first dc), keep the same peak-and-valley rhythm. Work until the body measures about 4.5 inches from the foundation row.

Section 3: Attaching Body to Band
Lay the chevron panel right side up and align its bottom edge with the top edge of the ribbed tube. Center the panel so the front opening lands correctly. Whip stitch them together with matching yarn, easing any extra fabric evenly.
Section 4: Double Ruffle Construction
Switch to the F-5 hook.
First ruffle: Join navy at the top right corner of the body. Ch 3, work 2 dc in every stitch across for instant fullness. Continue in the chevron pattern for six more rounds.
Second ruffle: Join yarn again at the base of the first ruffle and repeat the same process so the two layers stack.

Section 5: Picot Edging on Ruffles
With white yarn and the E-4 hook, work the picot edging along the bottom of each ruffle tier exactly as described in the special stitches section. Keep the tension relaxed.
Section 6: Button Band Finishing
Along each center-front edge, work a row of single crochet for a clean button band. On the right side (as worn), mark five even buttonhole spots. Create each buttonhole with chain 2, skip 2 stitches. Sew the five anchor buttons to the left band so they line up perfectly.
Skirt Instructions
Section 1: Ribbed Waistband
With E-4 hook and navy, chain 17.
Row 1: Sc in second chain and across. 16 sc.
Row 2: Ch 1, sc in BLO across. Repeat until the strip measures 26–28 inches. Join the short ends into a tube with the seam at center back.
Section 2: Grommet Placement
Mark eight evenly spaced spots along the center front of the waistband—four on each side of the middle, about one inch apart. Reinforce each spot on the wrong side with a small stabilizer square, then set the grommets according to the tool instructions.
Section 3: First Ruffle Tier
Switch to F-5 hook. Join navy to the bottom edge of the waistband. Ch 3, work 2 dc in every stitch around for fullness. Continue in the chevron pattern for eight rounds.
Section 4: Second Ruffle Tier
Join yarn again at the bottom of the first tier and work ten rounds of chevron for extra length and drama.

Section 5: Picot Edging
Work the white picot trim along the hem of both ruffle tiers the same way you did on the top.
Section 6: Corset Lacing
Thread the ribbon or cord through the grommets in a classic criss-cross pattern, starting at the bottom and finishing with a bow at the top. Adjust the tightness until the waistband hugs just right.
Finishing Your Nautical Crochet Set
Wet block both pieces. Soak them in cool water, gently squeeze out excess moisture, and pin them to the finished measurements on blocking mats. Let them dry completely so the chevron waves open up and the ruffles settle into perfect shape.
Weave in every remaining end. If you want extra nautical flair, sew a couple of spare anchor buttons onto the skirt waistband for visual balance.
Sizing Adjustments
For a smaller size, drop one full 12-stitch chevron repeat from both starting chains and shorten the ribbed bands to match your measurements. For a larger size, add one full repeat and lengthen the bands. Always check gauge and measure as you go so the fit stays intentional.
Care Instructions
Hand wash in cool water with mild detergent. Lay flat to dry and reshape the ruffles while the fabric is still damp. Store the set folded so the ruffles keep their bounce. The cotton softens with every wash yet holds its shape beautifully.

FAQ’s
Can I use acrylic yarn instead of cotton?
You can, but cotton or a cotton blend gives better stitch definition and a cooler summer feel. Acrylic tends to look a bit fuzzier and may stretch more over time.
How do I keep the ruffles from looking limp?
Work the ruffle rounds with the larger hook and deliberately increase stitches in the first round. Blocking also helps the layers stand out instead of collapsing.
What if I hate sewing on buttons?
Try snap fasteners hidden under the button band or make the front a continuous panel and add a side zipper. The look changes slightly, but the set still works.
Can I make the skirt longer?
Absolutely. Add extra rounds to the second ruffle tier or introduce a third tier. Just budget more yarn.
Do the grommets need special tools?
A basic grommet setter kit from any craft store does the job. Reinforce the fabric first so the holes stay neat.
Is the set wearable without the lacing?
The waistband has enough stretch to pull on, but the lacing gives you fine-tuned fit and the full nautical look. IMO the bow is worth the extra minute.
You Did It!
You now own a coordinated navy blue nautical set that looks like it came from a high-end coastal boutique. The chevron waves, dramatic double ruffles, white picot edges, and those little anchor buttons create something that feels special every time you put it on. Wear it to a beach brunch, a summer party, or just around the house when you need a confidence boost. Either way, you made it—and it shows.
