Navy Blue Nautical Crochet Ruffle Set Free Pattern
There is something timeless about nautical style. The crisp combination of navy blue and white, the suggestion of sea breezes and salt air, the way a well-crafted piece can feel both classic and completely fresh — it never goes out of fashion, and it translates beautifully into crochet. If you have been looking for a project that combines elegant ruffles with that iconic coastal color palette, this navy blue nautical crochet ruffle set is exactly what you need. Best of all, this pattern is completely free, and it is written for crocheters of every skill level who want to create something truly special.
In this post, you will find the complete free pattern for a coordinating crochet ruffle set worked in navy blue yarn. The set includes a ruffled top and a matching ruffle-trimmed skirt, both designed with that breezy nautical spirit in mind. Whether you are making this for a little girl, a toddler, or even adapting it for yourself, the instructions below will walk you through every stitch.
Why Navy Blue and Nautical Go Together So Perfectly
Before we dive into the pattern, let us take a moment to appreciate why the nautical aesthetic has endured for so long. Navy blue has been associated with the sea since the days of the Royal Navy, when deep indigo-dyed wool was the standard uniform color for sailors. Over time, that connection between navy blue and maritime adventure became deeply embedded in fashion and decorative arts alike.
In crochet, navy blue yarn has a richness that photographs beautifully and pairs effortlessly with white, cream, coral, and gold. Ruffles, meanwhile, evoke the frothy foam of ocean waves crashing on a shore — there is an organic, fluid quality to a well-worked ruffle that feels inherently connected to water. Put the two together and you have a combination that is hard to beat for charm and visual impact.
This set draws on those ideas deliberately. The ruffles are worked to cascade lightly, mimicking the layered look of waves, while the navy blue yarn anchors the whole piece with depth and sophistication.
Materials You Will Need
To complete this nautical crochet ruffle set, gather the following supplies before you begin.
For yarn, you will want a medium weight (category 4) yarn in navy blue as your main color. You will need approximately 400 yards for a child’s size 2T-3T, scaling up to about 600 yards for a size 4T-6. A small amount of white yarn — around 80 yards — will be used for optional accent details on the ruffle edges. Cotton or cotton-blend yarn works especially well for this pattern because it gives the ruffles a lovely drape and is comfortable against skin in warm weather. Popular choices include Lion Brand 24/7 Cotton, Paintbox Simply DK in cotton, or Drops Paris.
For your hook, a size 5mm (H/8) crochet hook is recommended as the starting point, though you should always make a gauge swatch and adjust accordingly.
Additional materials include a yarn needle for weaving in ends, scissors, stitch markers, a measuring tape, and optionally a few small anchor or shell buttons for decorative purposes on the straps or waistband.
Gauge and Sizing
Gauge matters for this project if you want the set to fit as intended. Work a 4-inch by 4-inch swatch in half double crochet using your chosen yarn and hook. You are aiming for approximately 14 stitches and 10 rows per 4 inches. If your swatch is larger, go down a hook size. If it is smaller, go up a hook size.
The pattern as written is sized for children as follows: Size 1 fits approximately 12-18 months with a chest measurement of 19-20 inches. Size 2 fits approximately 18-24 months with a chest measurement of 20-21 inches. Size 3 fits 2T-3T with a chest of 21-22 inches. Size 4 fits 4T-6 with a chest of 22-24 inches. Adjustments for larger or smaller sizes are noted throughout the pattern.
Abbreviations Used in This Pattern
The following standard US crochet abbreviations are used throughout. Ch means chain. St means stitch. Sl st means slip stitch. Sc means single crochet. Hdc means half double crochet. Dc means double crochet. Tr means treble crochet. Inc means increase (two stitches worked in the same stitch). Dec means decrease. Rep means repeat. Sk means skip. BLO means back loop only. FLO means front loop only. Sp means space. PM means place marker. RS means right side. WS means wrong side.
The Nautical Ruffle Top Pattern
Starting the Bodice
The top is worked from the top down, beginning with the back panel. Foundation chain: Using navy blue yarn, ch 38 (40, 44, 48) depending on your size.
Row 1 (WS): Starting in the 3rd ch from hook, hdc across. You should have 36 (38, 42, 46) hdc. Ch 2, turn.
Rows 2-8: Hdc across each row. Ch 2, turn at end of each row. This creates the back bodice panel. When you have completed row 8, do not turn. Instead, ch 12 (14, 14, 16) for the strap. Sl st to the other end of row 8 to create a strap loop. Cut yarn and pull through. Rejoin at opposite end and repeat for the second strap.
Alternatively, you can work continuous straps by picking up stitches at each shoulder and working them upward, which creates a sturdier construction. For simplicity, the tied strap method is described here, but either works beautifully.
The Front Bodice Panel
Work exactly as the back panel through row 8. On the front panel, you will create a small optional anchor motif in white yarn as a decorative detail. To do this, after completing row 4, use a separate strand of white yarn and surface slip stitch a simple anchor shape onto the center of the front panel once the piece is complete. The motif is entirely optional but adds a wonderful nautical touch.
Joining the Bodice
With RS facing, sl st the side seams of the front and back panels together using whip stitch or sl st seam through the BLO. Leave the top open for the straps and the bottom open for attaching the ruffle skirt. You should now have a joined bodice tube that is open at both the top and bottom.
Working the Bodice Ruffle Band
At the bottom edge of the joined bodice, you will add the first ruffle band before attaching the skirt.
Round 1: Join navy blue yarn to the bottom edge of the bodice. Work 2 sc in each stitch around the entire bottom edge. Join with sl st to the first sc. Ch 1.
Round 2: Work 2 sc in each sc around. Join with sl st. This doubling creates the fullness of the ruffle.
Round 3: Dc in each st around. Join with sl st.
Round 4: Work 2 dc in each st around. Join with sl st. Ch 3, turn.
Round 5: Tr in each st around. Join with sl st. Fasten off, leaving a long tail for seaming.
This ruffle band creates a beautiful cascading effect at the waist of the top. If you are using white yarn for contrast, you can work round 5 in white instead of navy for a classic nautical stripe effect.
Neckline and Armhole Finishing
Around each armhole opening, work one round of sc evenly around, then one round of reverse sc (also called crab stitch) for a polished edge. This keeps the armholes from stretching out and adds a neat finish.
For the neckline, work the same — one round sc followed by one round reverse sc. If you prefer a more decorative edge, work one round of shell stitch instead: (Sc, ch 2, 3 dc, ch 2, sc) in every 5th stitch around the neckline for a scalloped effect reminiscent of ocean waves.
The Nautical Ruffle Skirt Pattern
The skirt is worked in the round from the waistband down. It can be worn as a standalone piece or attached directly to the bodice top for a dress effect.
The Waistband
Ch 4 and join with sl st to form a ring, or use a magic ring. This is the starting point of a worked-in-the-round waistband.
Round 1: Ch 2. Work 60 (64, 70, 76) hdc into the ring — or more accurately, chain the number matching your child’s waist measurement at roughly 3 stitches per inch. Join with sl st.
Rounds 2-4: Hdc in each st around. Join with sl st after each round. This creates a 4-row waistband that can fold over to create a casing for an elastic waistband if desired.
To add elastic: After completing the waistband rounds, fold the band in half to the inside of the skirt and sl st in place around the bottom of the fold, leaving a small gap. Thread 3/4-inch elastic through the casing, adjust to fit comfortably, and close the gap. This creates a practical, comfortable waistband perfect for little ones.
The Skirt Body
Now you will begin building the skirt body, which creates the base onto which the ruffle tiers are worked.
Round 1 (Increase Round): Ch 2. Work 2 hdc in every stitch around. Join with sl st. You have now doubled your stitch count.
Rounds 2-4: Hdc in each st around. Join with sl st.
Round 5 (Second Increase Round): Work (2 hdc in next st, hdc in next st) around. Join with sl st.
Rounds 6-8: Hdc in each st around. Join with sl st.
Round 9 (Third Increase Round): Work (2 hdc in next st, hdc in next 2 sts) around. Join with sl st.
Rounds 10-12: Hdc in each st around. Join with sl st. You should now have a nicely flared skirt body that will serve as the framework for the ruffle tiers.
The Ruffle Tiers
This is where the magic of the nautical crochet ruffle set really comes alive. You will work three ruffle tiers at evenly spaced intervals down the skirt.
First Ruffle Tier (worked after round 4 of the skirt body):
Join yarn to any stitch in the round 4 row of the skirt. Work in the FLO of that round.
Row 1 of ruffle: Work 2 dc in each FLO st around. Join with sl st. Ch 3.
Row 2 of ruffle: Work 2 dc in each st around. Join with sl st. Ch 3.
Row 3 of ruffle: Work (dc, tr, dc) in each 3rd stitch, dc in remaining stitches around. Join with sl st. Fasten off.
This creates a full, cascading ruffle that fans out beautifully from the skirt body. Return to the BLO of round 4 and continue working the skirt body normally.
Second Ruffle Tier (worked after round 8 of the skirt body):
Repeat the ruffle process in the FLO of round 8. Because the skirt is wider at this point, the ruffle will naturally be fuller. Work exactly as the first tier.
Third Ruffle Tier (worked at the hem after round 12):
For the hem ruffle, work a slightly extended version for maximum drama.
Row 1: Work 2 dc in each st around. Join, ch 3.
Row 2: Work 2 dc in each st around. Join, ch 3.
Row 3: Work 2 tr in each st around. Join, ch 4.
Row 4: Work (2 tr, ch 1) in each st around. Join, ch 1.
Row 5: Sc in each st and ch-1 sp around. Fasten off.
If you want the classic navy and white nautical look, work rows 4 and 5 of the hem ruffle in white yarn. The contrast is striking and ties the set together visually.
Optional White Accent Details
The nautical theme really sings when you incorporate white accents thoughtfully. Beyond the hem ruffle option described above, consider working a single round of white sc at the very top edge of the waistband for a crisp finishing line. You can also use white yarn to sl st a simple rope or wave motif onto the front bodice panel as a surface embellishment.
Anchor buttons or shell buttons in white or gold affixed to the shoulder straps of the top are another charming touch that reinforces the coastal theme without requiring any additional yarn work. Look for these at craft stores in the notions section, or search for nautical buttons online.
Finishing Your Set
Once all pieces are complete, weave in all ends thoroughly using your yarn needle. Block the finished pieces by lightly misting with water and laying flat to dry, shaping the ruffles gently as you go. Blocking is especially worthwhile with cotton yarn because it opens up the stitches, evens the tension, and gives the ruffles a beautiful drape that really elevates the finished look.
If you are making the set as a dress by joining the top and skirt, simply sl st the waistband of the skirt to the bottom ruffle band of the bodice top, adjusting the strap length as needed so the waistline falls in the right place. Give the joined seam a gentle press with a damp cloth and you are done.
Caring for Your Nautical Crochet Ruffle Set
Cotton and cotton-blend yarns are generally easy to care for. Most can be machine washed on a gentle cycle in cold water and laid flat to dry. Avoid putting crocheted items in a hot dryer as this can shrink the fibers and distort the ruffles. If you used an acrylic or acrylic-blend yarn instead, check the yarn label for specific care instructions. A gentle hand wash and lay-flat dry is always the safest option for preserving the shape and drape of the ruffles.
Tips for Customizing This Pattern
One of the most wonderful things about free crochet patterns is the room they leave for personalization. Here are a few ideas for making this nautical ruffle set uniquely your own.
Swap out the navy blue for a soft coral or bright red and pair it with white ruffles for a different take on the nautical color story. Red and white stripes with white ruffles is a classic alternative that photographs beautifully outdoors against a beach backdrop.
Add a crocheted flower or starfish appliqué to the front bodice for a sweet decorative element. You can find simple starfish patterns with a quick search and attach them with just a few stitches.
For a more bohemian feel, work the ruffles in a variegated blue-and-white yarn that creates a natural stripe effect without requiring yarn changes. This technique is especially stunning for the skirt tiers.
Lengthen the skirt by adding more rounds between the ruffle tiers and a fourth tier at the hem. This transforms the set from a playful summer outfit into something more formal and special-occasion-worthy.
