This is a classic bubble-style baby romper worked in single crochet with a sweet pumpkin applique on the front. The construction is straightforward. You will use basic stitches throughout the main body, add a decorative shell border around the bib, and finish with a three-dimensional pumpkin that gives it all that cozy fall charm.
I love how this design combines a timeless romper silhouette with seasonal details that are not over the top. The burnt orange color, the cream shell frame around the bib, and that little stuffed pumpkin with its curling vine make this the perfect outfit for autumn photo sessions, pumpkin patch visits, or simply keeping your little one looking adorable during the cooler months.
The romper is sized for 3 to 6 months and features adjustable button straps plus a snap or button crotch closure for easy diaper changes. If you are comfortable with basic shaping and seaming, you can absolutely tackle this project.
Why You Will Love This Crochet Baby Romper Pattern
This autumn pumpkin baby romper hits that sweet spot between impressive and achievable. The main body uses only single crochet, which creates a dense, structured fabric perfect for baby garments. The intermediate rating comes from managing a few different techniques rather than difficult stitches.
You will work the front and back panels flat, shape the leg openings with simple increases and decreases, construct a square bib with a granny-style border, and create a cute stuffed pumpkin applique. Each piece is manageable on its own. When you assemble everything, you get a romper that looks like it took far more skill than it actually requires.
The finished piece has a boxy, relaxed fit through the torso with gathered leg openings. Those wooden buttons on the straps and crotch add a natural, handmade feel that photographs beautifully.
Materials You Will Need
Before you start, gather these supplies:
Yarn:
Hook: US size G-6 / 4.0 mm (adjust to meet gauge)
Notions:
Yarn Suggestions
Any smooth worsted weight cotton or cotton-blend that meets gauge will work beautifully. Here are some specific options:
Lion Brand 24/7 Cotton works wonderfully for this project. It is 100% mercerized cotton with crisp stitch definition and washes like a dream. Grab 2 skeins in Terracotta or Pumpkin Spice for Color A, 1 skein in Ecru for Color B, and a small amount of Olive for Color C.
Paintbox Yarns Simply DK Cotton is another excellent choice with a matte finish that matches the look in the photos. You may need to use a US H-8 / 5.0 mm hook and reswatch to match gauge.
Avoid fuzzy or textured yarns. They will obscure the stitch definition and make the shell border less crisp.
Gauge
18 single crochet stitches by 22 rows equals 4 inches by 4 inches (10 cm by 10 cm), worked in single crochet and blocked.
Gauge matters here. Even being one stitch off per four inches will throw off your finished chest measurement. Make a swatch of at least 20 stitches by 24 rows, block it the way you plan to block the finished romper, and measure the center 4 inches before you start.
Finished Measurements
This pattern is written for size 3 to 6 months.
Abbreviations and Stitch Definitions
Here are all the stitches you will use in this crochet tutorial:
Shell stitch: Work 3 double crochet stitches into the same stitch or space. This creates one shell unit.
Magic ring: Make a loop with your yarn, insert your hook through the loop, yarn over and pull up a loop, chain 1 (this chain does not count as a stitch). Work the specified stitches into the ring, then pull the yarn tail to close the center hole.
Pattern Notes Before You Begin
Read through these notes before starting. They will save you confusion later.
1. The back panel and front lower body are worked flat, back and forth in rows. The turning chain at the start of each row does NOT count as a stitch throughout this entire pattern.
2. The bib is worked upward directly from the top edge of the front lower body. You do not cut the yarn between sections.
3. Right side (RS) and wrong side (WS) are noted at key points. The RS is the side facing you on Row 1 of each panel.
4. Stitch counts appear in parentheses at the end of each row, like this: (42 sc).
5. Use stitch markers to track increase points at the leg openings. Move them up as you work each row.
6. All pieces should be blocked before assembly for the cleanest finish.
7. Color A is used for all main body sections, straps, and the pumpkin applique. Color B is used only for the bib border. Color C is used only for the pumpkin stem and vine.

Front Bib
The bib is worked on the center 19 stitches of Row 32. Here is how to find them: Row 32 has 37 stitches. The center 19 stitches begin at stitch 10 and end at stitch 28. This leaves 9 stitches on each side.

Bib Rows 1 through 18: Chain 1, single crochet across. Turn. (19 sc each row)
Fasten off, leaving a long tail for assembly.
Checkpoint: After completing the bib, the front piece from foundation chain to top of bib should measure approximately 9 inches (23 cm) tall.
Bib Border
The bib border creates that beautiful granny-square-style shell frame you see in the photos. You will work it around all four edges of the bib panel using Color B.
Round 1 (pickup round): With Color B, join with a slip stitch to any corner of the bib panel. Chain 1.
Work across the top edge: 19 single crochet. At the corner, work (1 single crochet, chain 2, 1 single crochet).
Work down the right side: 18 single crochet evenly (approximately 1 single crochet per row end). At the corner, work (1 single crochet, chain 2, 1 single crochet).
Work across the bottom edge: 19 single crochet. At the corner, work (1 single crochet, chain 2, 1 single crochet).
Work up the left side: 18 single crochet evenly. At the corner, work (1 single crochet, chain 2, 1 single crochet).
Slip stitch to first single crochet to join. (74 sc plus 4 corner chain-2 spaces)
Round 2 (shell round): Chain 3 (this counts as your first double crochet), work 2 double crochet in same stitch to complete your first shell. Skip 2 stitches, slip stitch in next stitch, skip 2 stitches, work 3 double crochet (one shell) in next stitch. Repeat from to around each side. At each corner chain-2 space, work (3 double crochet, chain 2, 3 double crochet). Slip stitch to top of beginning chain-3 to join.
Fasten off Color B. Weave in ends.
Pumpkin Applique
This is the fun part. You will create a three-dimensional stuffed pumpkin to attach to the center of the bib.
Pumpkin Body
With Color A, make a magic ring.
Round 1: Chain 1, work 6 single crochet into ring. Pull ring closed. Slip stitch to first single crochet to join. (6 sc)
Round 2: Chain 1, work 2 single crochet in each stitch around. Slip stitch to first single crochet to join. (12 sc)
Round 3: Chain 1, single crochet in next stitch, work 2 single crochet in next stitch. Repeat from to around. Slip stitch to first single crochet to join. (18 sc)
Round 4: Chain 1, single crochet in next 2 stitches, work 2 single crochet in next stitch. Repeat from to around. Slip stitch to first single crochet to join. (24 sc)
Rounds 5 and 6: Chain 1, single crochet in each stitch around. Slip stitch to join. (24 sc each round)
Creating the Pumpkin Segments
Thread a yarn needle with Color A. Using long surface slip stitches, pull the yarn from the center back of your disc to the outer edge at 6 evenly spaced points. That is every 4th stitch on the outer edge (24 stitches divided by 6 segments equals 4 stitches per segment). Pull slightly to create those characteristic indented pumpkin lobes. Secure on the back. Your disc will curve upward and look three-dimensional.
Round 7 (optional, for a cleaner finish): Work on WS. Chain 1, single crochet in next 2 stitches, sc2tog. Repeat from to around. Slip stitch to join. (18 sc)
Stuff lightly with a tiny amount of fiberfill or yarn scraps before closing.
Round 8: Chain 1, single crochet in next stitch, sc2tog. Repeat from to around. Slip stitch to join. (12 sc)
Round 9: Chain 1, sc2tog around. Slip stitch to join. (6 sc)
Fasten off, leaving a tail. Thread the tail through the remaining 6 stitches and pull to close. Knot and weave in.
Stem and Vine
Stem: With Color C, chain 5. Starting in 2nd chain from hook, slip stitch in each of next 4 chains. (4 slip stitches) Fasten off, leaving a 6-inch (15 cm) tail for sewing.
Vine: With Color C, chain 8. Slip stitch in 2nd chain from hook, slip stitch in next chain, single crochet in next chain, half double crochet in next 2 chains, single crochet in next chain, slip stitch in last chain. Fasten off.
Sew the stem to the top of the pumpkin body. Curl the vine and tack it to the stem with your yarn needle. The finished pumpkin should measure approximately 1.75 inches (4.5 cm) in diameter.
Sew the completed pumpkin applique to the center of the bib panel using the yarn tail and a yarn needle. Take small stitches around the perimeter of the pumpkin, through the bib fabric, to secure it firmly.
Straps (Make 2)
With Color A, chain 6.
Row 1: Single crochet in 2nd chain from hook and in each chain across. Turn. (5 sc)
Rows 2 through 35: Chain 1, single crochet in each stitch across. Turn. (5 sc each row)
Row 36 (buttonhole row): Chain 1, single crochet in first 2 stitches, chain 1, skip 1 stitch, single crochet in last 2 stitches. Turn. (4 sc plus 1 chain-1 space)
Row 37: Chain 1, single crochet in first 2 stitches, single crochet in chain-1 space, single crochet in last 2 stitches. Turn. (5 sc)
Row 38 (second buttonhole row): Chain 1, single crochet in first 2 stitches, chain 1, skip 1 stitch, single crochet in last 2 stitches. Turn. (4 sc plus 1 chain-1 space)
Row 39: Chain 1, single crochet in first 2 stitches, single crochet in chain-1 space, single crochet in last 2 stitches. Turn. (5 sc)
Rows 40 through 42: Chain 1, single crochet across. Turn. (5 sc each row)
Fasten off.
Each strap measures approximately 7.5 inches (19 cm) long by 1.1 inches (2.75 cm) wide. The two buttonholes near one end allow you to adjust the fit as baby grows.
For a professional finish, work a border of slip stitches around the entire perimeter of each strap. This is optional but makes a noticeable difference.
Crotch Button Band
The crotch opening runs along the bottom edge of the front lower body and closes with buttons for easy diaper access.
With Color A, join yarn at the bottom right corner of the front panel foundation chain edge.
Row 1: Chain 1, single crochet evenly across the bottom edge of the front panel. Turn. (43 sc)
Row 2: Chain 1, single crochet across. Turn. (43 sc)
Row 3 (buttonhole row): Chain 1, single crochet in first 5 stitches, chain 1, skip 1 stitch, single crochet in next 9 stitches. Repeat from to 3 more times, ending with single crochet in last 3 stitches. Turn.
Fasten off.
Work a matching band on the back panel bottom edge (without buttonholes) so the two edges align when buttoned.
Assembly
1. Block all pieces before seaming. Lay them flat, spray lightly with water, pin to size, and let dry completely.
2. Seam the side edges of the front and back panels together using a mattress stitch or whip stitch. Start at the underarm and work down to where the leg opening begins.
3. Attach the straps to the back panel first by sewing the non-buttonhole end securely to the back upper corners. Then sew 2 wooden buttons to the front panel at each shoulder, positioned to align with the strap buttonholes.
4. Sew buttons to the back crotch band, positioned to align with the buttonholes on the front crotch band.
5. Weave in all remaining ends and give the finished romper a final light blocking.
Tips for Success
Take your time with the bib border. The shell round can feel tricky the first time you work it, but once you establish the rhythm of skip 2, slip stitch, skip 2, shell, it flows quickly.
When sewing the pumpkin applique, use matching thread and small stitches so the attachment is invisible from the front. The pumpkin should sit slightly raised from the bib surface for that three-dimensional effect.
The double buttonholes on each strap are intentional. They give you two positions for the buttons, which extends the wearable life of the romper as baby grows.
This autumn pumpkin baby romper is the kind of project that makes people ask, "You made that?" The construction is simpler than it looks, and the finished result is genuinely adorable. I hope you enjoy making it as much as I enjoyed designing it.
