A navy nautical striped mini dress that looks straight off a vintage postcard? Let us make it happen. This dress is worked top down in continuous rounds with just one stitch — single crochet — so the construction is about as straightforward as garments get. The stripes do all the visual work.
Here is what makes this pattern so clever: negative ease in the bodice gives you that fitted sailor look without any complicated shaping, then aggressive increase rounds turn the skirt into a dramatic 1950s flare. And because you never turn your work or join rounds, the whole thing is one smooth, seamless tube until the finishing.
Fair warning: this is a big project. The skirt grows to 280 stitches at the hem, so the later rounds take real time. But if you love rhythmic, meditative crochet with a showstopper payoff, this dress is your next big make.
Why You Will Love This Navy Nautical Flared Mini Dress
The silhouette is everything here. Fitted bodice, nipped waist, dramatically flared skirt — it fans out like a vintage sundress. The squared neckline and spaghetti-style braided straps finish the sailor look.
The stripe colorwork sounds fancier than it is. You alternate colors every two or three rounds and carry the unused yarn up the inside by crocheting over it loosely. No charts, no floats, no cutting and rejoining every round.
Cotton or cotton-blend yarn is strongly recommended. Cotton has less stretch than acrylic, which keeps the fitted bodice in shape, and it gives excellent stitch definition so the navy and white stripes pop beautifully.
Skill Level and Time Commitment
This is an intermediate crochet pattern. The stitches themselves are beginner-friendly — single crochet throughout — but the project asks for comfort with continuous rounds without joining, stripe colorwork management, evenly spaced increase and decrease rounds, and simple braided embellishments.
If you have never made a garment before, this is a great first dress project because the construction is straightforward. The challenge is keeping your tension even and managing two colors neatly.
Time estimate: Approximately 25 to 40 hours depending on your speed. The bodice takes roughly 8 to 12 hours. The skirt, with its growing stitch counts, takes 15 to 25 hours. Finishing, blocking, and the braided straps add 2 to 3 hours.
Materials You Will Need
Gather everything before you start and the project flows so much better. Here is what you need:
Yarn:
- Yarn A (Navy): Approximately 900 yards / 823 meters
- Yarn B (White): Approximately 700 yards / 640 meters
- Total: Approximately 1600 yards / 1463 meters
- Yarn weight: DK weight (CYCA #3 Light), 100% cotton or cotton-blend recommended
Suggested yarn options:
- Lion Brand 24/7 Cotton (100% mercerized cotton, 186 yards per 100g skein) — smooth with excellent stitch definition. You will need approximately 5 skeins Navy and 4 skeins White.
- Paintbox Yarns Simply DK (100% premium acrylic, 137 yards per 50g ball) — budget-friendly with great color saturation. You will need approximately 7 balls Navy and 6 balls White.
- Drops Safran (50% cotton, 50% linen, 175 yards per 50g ball) — the linen content adds structured drape that suits the nautical aesthetic. You will need approximately 6 balls Navy and 5 balls White.
Avoid fuzzy or hairy yarns — they obscure the crisp stripe contrast.
Hook:
- US size E-4 / 3.5 mm crochet hook (or size needed to obtain gauge)
Notions:
- Stitch markers (at least 4)
- Tapestry needle for weaving ends
- Measuring tape
- Scissors
- Optional: dress form or blocking mats
Gauge
20 sc x 22 rows = 4 inches / 10 cm in single crochet, worked in continuous rounds, blocked.
Gauge is mandatory for this garment. A difference of even 1 stitch per 4 inches will result in a significant size difference across the bodice circumference. Make a flat gauge swatch at least 5 inches x 5 inches, block it, then measure the center 4 inches. Adjust your hook size up or down as needed before beginning.

Special Techniques
Stripe Single Crochet
This dress uses single crochet in continuous rounds with color changes carried up the inside. At the last yarn-over of the final sc before a color change, pull through the new color instead of the working color. Do not cut yarn between colors. Carry the unused yarn along the inside by crocheting over it loosely on every round it is not in use. This keeps floats short and the interior neat.
Working in Continuous Rounds
You will work without turning and without joining at the end of each round. Place a removable stitch marker at the beginning of each round and move it up as you work. The right side faces outward at all times. Because rounds spiral slightly, you may notice a slight jog between color changes. This is normal for continuous-round stripe work.
Braided Straps
Each strap is made from 3 individual crochet chains worked with both colors held together, then braided. Full instructions appear in the Straps section.
Pattern Notes Before You Begin
- The dress is worked in continuous rounds from the top down with no join or turning chain.
- The foundation chain forms the neckline and is joined to create a ring.
- The bodice achieves its fitted look through negative ease. The single crochet fabric stretches around the body.
- Waist shaping uses decrease rounds followed by increase rounds.
- The skirt flare is created through aggressive, evenly spaced increase rounds. The skirt grows from 140 stitches at the waist to 280 stitches at the hem.
- Bodice stripe sequence: 2 rounds YA, 2 rounds YB, repeated throughout.
- Skirt stripe sequence: 3 rounds YA, 3 rounds YB, repeated throughout.
- All stitch counts include the marker stitch.

CHECKPOINT: After Round 106, total piece height should be approximately 26 inches / 66 cm from neckline. Hem circumference should measure approximately 56 inches / 142 cm. The skirt should fan outward dramatically.
Hem Finish
At the end of Round 106, with YA, sl st in each st around the hem edge. This creates a clean, firm navy border. Fasten off. Weave in end.
Neckline Finish
With YA and hook, join yarn at any point along the top neckline edge. Sl st in each st around the neckline. Sl st to join. Fasten off. Weave in end. This stabilizes the neckline and creates a matching navy edge.
Braided Straps
The dress has 2 braided spaghetti straps. Each strap is composed of 3 crocheted cords braided together.
Strap Cord (make 6 total, 3 per strap):
With YA and YB held together as one, ch 90. Fasten off leaving a 12-inch / 30 cm tail at each end for attachment.
Braiding the Strap:
Group 3 cords together. Hold all 3 at one end and tie a loose knot to anchor during braiding. Braid in a standard 3-strand braid. When complete, the braided strap should measure approximately 12 inches / 30 cm.
Strap Attachment:
Hold the bodice with the right side facing. Identify front center. Measure 3.5 inches / 9 cm to the left and right of center. These are the front attachment points.
Thread tail ends onto a tapestry needle. Insert through the front neckline edge at the attachment point from outside to inside, passing through 2 to 3 stitches. Knot firmly on the inside. Double-secure with another knot.
For back attachment, try the dress on or place it on a dress form. Bring the straps over your shoulders to a comfortable length and mark the back attachment points. Attach as described above.
Trim the excess after knotting. Finished braids should sit flat across the shoulder.
Blocking and Finishing
Weave in all ends throughout the dress. There will be many color-change ends along the inside of the bodice. Weave each over at least 1 inch in multiple directions to prevent unraveling.
Wet blocking: Submerge the dress in cool water. Gently press out excess water without wringing. Roll in a clean towel. Lay flat on blocking mats. Shape the bodice to the correct dimensions. Fan out the skirt evenly in a circular shape. Pin the hem if desired. Allow to dry completely, approximately 24 to 48 hours.
Blocking is especially important for cotton to set stitch definition and relax the fabric.
Size Customization Tips
- To size up: Add stitches to the foundation chain in multiples of 10. Adding 10 stitches (chain 180) adds approximately 2 inches of circumference. Adjust the waist decrease math proportionally.
- To size down: Subtract stitches in multiples of 10. Chain 160 for size XS.
- To lengthen the bodice: Add more 2-round stripe repeats between the neckline and waist shaping. Each 2-round repeat adds approximately 0.36 inches.
- To lengthen the skirt: Add more 6-round increase blocks after Round 106. Each block adds approximately 1.1 inches and 10 stitches.
- To shorten: Remove skirt increase blocks from the end. Fewer blocks will also reduce flare width.
Care Instructions
Machine wash on gentle in cold water if using machine-washable cotton. Use a mesh laundry bag to protect the braided straps. Do not tumble dry. Lay flat or hang briefly to dry. Do not wring or twist. Iron on low with a pressing cloth if needed. Store folded or hung, but avoid long-term hanging as the weight may stretch the neckline.
Tips for Success
- Do not skip the gauge swatch. Even 1 stitch per 4 inches off will noticeably change the bodice circumference.
- Move your round marker up every single round. In continuous rounds, losing your place is easy and painful.
- Weave in ends as you finish each color block instead of saving them all for the end.
- Try the dress on before attaching the back straps. Strap length is personal — get it right while you can still adjust.
- Block it. Blocking sets the stitch definition and relaxes the cotton, and it makes all the difference in the finished look.
