This is ONE of my absolute favorite baby projects to date, and I’m so excited to share it with you! The Lavender Ruffle Baby Playsuit works up faster than you might think, taking roughly 8 to 12 hours depending on your pace. That gorgeous ruffled collar? Way easier than it looks.
If you’ve been saving a special skein of soft lavender yarn for the perfect project, this is it. The combination of ribbed texture, delicate scalloped edges, and those sweet tie straps at the shoulders creates a showstopper piece that looks like it belongs in a boutique.
Trust me when I say this playsuit makes an incredible baby shower gift. Every person who sees it will assume you spent weeks on it. Our little secret that you didn’t.
Why You’ll Love This Baby Playsuit Crochet Pattern
This charming playsuit brings together several beautiful techniques in one cohesive garment. The off-shoulder ruffled collar gives it that vintage sweetness, while the ribbed bodice adds stretch and texture. Three wooden buttons run down the front placket, and adjustable tie straps mean you can customize the fit as baby grows.
The construction is smarter than it first appears. You’ll work the collar separately, build the bodice flat with a front opening, then join everything in the round for the shorts section. This approach keeps the project manageable and lets you see progress quickly.
Skill level: Intermediate. You should be comfortable working in the round, creating ribbed fabric, seaming pieces together, and finishing button bands. If you’ve made a basic garment before, you’re ready for this.
Who can resist a little one in soft lavender ruffles?
Materials You’ll Need
Gather these supplies before you start:
Yarn: Approximately 300 yards (274 meters) for size 3 to 6 months, or 375 yards (343 meters) for size 6 to 12 months. Use DK weight yarn (CYCA #3) in lavender or your preferred color.
Recommended yarn options:
- Lion Brand Pound of Love (100% premium acrylic, 975 yards per skein)
- Paintbox Yarns Simply DK (100% acrylic, 137 yards per 50 g ball)
- Drops Safran (50% cotton, 50% acrylic, 175 yards per 50 g ball)
Choose yarn with good drape and machine washability. Avoid fuzzy or heavily textured yarns since they’ll hide the beautiful ribbing and ruffle definition.
Hook: US size E-4 / 3.5 mm, or whatever size you need to match gauge.
Notions:
- Yarn needle
- Scissors
- 3 wooden shank buttons, approximately 12 mm diameter
- Sewing needle and matching thread for attaching buttons
- 4 to 6 locking stitch markers
- Rust-proof pins for blocking
FYI, a soft DK cotton-blend keeps the playsuit gentle on baby skin and easy to wash.
Finished Sizes
Size 3 to 6 months:
- Chest: 16 in / 40.5 cm
- Total length (shoulder to crotch): 13 in / 33 cm
- Leg opening: 5 in / 12.5 cm
Size 6 to 12 months:
- Chest: 18 in / 45.5 cm
- Total length (shoulder to crotch): 14.5 in / 37 cm
- Leg opening: 5.5 in / 14 cm
Throughout this pattern, instructions are written for size 3 to 6 months with size 6 to 12 months in parentheses. When only one number appears, it applies to both sizes.
Gauge
18 single crochet (sc) x 20 rows = 4 in / 10 cm worked in single crochet, blocked
14 half double crochet (hdc) x 12 rows = 4 in / 10 cm worked in half double crochet ribbing through the back loop only, blocked
Gauge matters here because this is a garment. If your stitches are too loose, the playsuit will be too big and saggy. Too tight, and baby won’t fit into it. Swatch first and adjust your hook size as needed.

Special Stitches Explained
Ribbing Stitch (hdc blo ribbing)
This creates that stretchy vertical texture you see on the bodice. Chain any number, then work half double crochet across. On every following row, chain 2 (does not count as a stitch) and work half double crochet in the back loop only of each stitch.
Always work the first stitch into the base of the chain-2 so the edge stays clean.
Scallop Edging
This decorative edge appears on the collar and leg openings. Slip stitch, chain 3, work 4 double crochet in the same stitch, skip 2 stitches, and slip stitch in the next. Repeat for a pretty shell border.
Ruffle Shell Stitch
This creates the gorgeous collar ruffle. Alternate single crochet with 5-double-crochet shells, then build the next row by working shells into the single crochets and single crochets into the center of previous shells.
Adjustable Tie Strap
Join yarn at the shoulder, chain 30 (or desired length), then slip stitch back down the chain to form a firm cord. Secure the base and tie the free end into a bow.
Step by Step Crochet Pattern Instructions
Section 1: Collar Ruffle
The collar is worked flat and attached later. It creates that beautiful off-shoulder look.
Chain the foundation, work three rows of ruffle shell stitch, then add scallop edging along the lower edge. Set it aside until the end.
Section 2: Bodice
Work the front and back panels in half-double-crochet back-loop-only ribbing. Split the front panel to create the button opening, then seam the sides. Leave the top and bottom open.
Checkpoint: The seamed bodice should measure approximately 6 inches tall and the correct chest circumference for your size.
Section 3: Lower Body and Shorts
Join yarn at the bottom of the bodice and work in the round. Shape the crotch with decreases, divide for the legs, and finish each leg opening with scallop edging.
Section 4: Button Band
Pick up stitches along the front placket, work a buttonhole row on one side, and finish with a firm edge. Sew on the three wooden buttons.
Section 5: Straps
Make four adjustable tie straps (two front, two back). Chain, slip-stitch back down for a sturdy cord, secure at the shoulders, and tie into bows.
Section 6: Collar Attachment
Pin the ruffle collar around the top edge of the bodice, centering it for the off-shoulder effect. Whipstitch it in place and weave in every end.
Block the finished playsuit so the ruffles open fully and the ribbing sits evenly.

FAQ’s
Can I make this in a different color?
Absolutely. Soft pastels, soft neutrals, or even a soft pink look just as sweet. Lavender just feels especially dreamy for this design.
Are the straps secure enough?
When slip-stitched firmly and tied in bows, they stay put. You can always add a tiny button or snap underneath for extra security if you prefer.
How do I keep the ruffles from looking messy?
Consistent tension and a good blocking session make all the difference. The scallop edging also helps the edges stay neat.
Is this suitable for beginners?
Confident beginners who already know ribbing, shells, and basic seaming can handle it. Take each section one step at a time.
How do I wash the finished playsuit?
Machine wash on gentle in cool water and lay flat to dry. Choose a soft, machine-washable DK yarn for best results.
Can I adjust the length?
Yes. Add or remove rows in the bodice or extra rounds in the shorts section. The modular construction makes length changes straightforward.
Final Thought
There you have it—a soft, ruffled playsuit that looks boutique-ready but comes together in a surprisingly manageable number of hours. The ribbed bodice gives stretch and structure, the cascading collar adds pure charm, and those wooden buttons plus adjustable straps make it practical as well as pretty.
IMO, the moment you attach the ruffle collar is when the whole piece transforms from “cute project” into “showstopper.” Take your time with the seams and the blocking, and enjoy every lavender stitch.
When that little one is finally bouncing around in their handmade playsuit, every hour will feel completely worth it. Happy crocheting, friend!
