Materials Needed

Before you begin, gather the following materials. Having everything ready will make your knitting experience smooth and enjoyable.

Yarn

• Worsted weight cotton or cotton-blend yarn in soft butter yellow (approx. 300-350 yards). Cotton is ideal for this project because it's breathable, durable, and machine-washable—perfect for baby items.

Needles & Hooks

• US Size 6 (4.0 mm) knitting needles (straight or circular for flat knitting)
• US Size E/4 (3.5 mm) crochet hook for the edging

Notions

• Stitch holders or waste yarn
• Tapestry needle for weaving in ends
• Two wooden buttons (approximately ½ inch diameter)
• Scissors
• Measuring tape
• Stitch markers (optional but helpful)

Gauge

20 stitches and 28 rows = 4 inches in stockinette stitch (knit flat). Be sure to check your gauge before starting—this ensures your finished romper will match the intended measurements. If your gauge is off, adjust your needle size accordingly.

Step-by-Step Instructions

This pattern is written for sizes 0-3 months (3-6 months, 6-12 months). Finished chest measurements are 16 (18, 20) inches, and length is 14 (16, 18) inches. The instructions are provided for the smallest size, with larger sizes in parentheses. Follow the numbers that correspond to your desired size throughout.

Abbreviations

• K = knit
• P = purl
• K2tog = knit two stitches together (decrease)
• SSK = slip, slip, knit (decrease)
• YO = yarn over (increase/hole)
• RS = right side
• WS = wrong side
• St(s) = stitch(es)
• Rep = repeat
• M1 = make one (increase by lifting the bar between stitches and knitting into the back of it)

Legs (Make 2)

You'll begin by knitting the two legs separately, then join them to create the body of the romper.

1. Cast on 36 (40, 44) stitches.
2. Work in stockinette stitch (Knit on RS, Purl on WS) for 2 inches, ending with a WS row.
3. Shape crotch: On the next RS row, increase 1 stitch at each end as follows: K1, M1, knit to the last stitch, M1, K1. You now have 38 (42, 46) stitches.
4. Work 3 rows even (no increases).
5. Repeat the increase row every 4th row 2 more times. You now have 42 (46, 50) stitches.
6. Work even (no shaping) until the leg measures 5 (6, 7) inches from the cast-on edge.
7. Place the stitches on a holder or waste yarn. Repeat the entire process for the second leg.

Body

Now you'll join the two legs to create the main body of the romper.

1. Join legs: With the RS facing, knit across the stitches of the first leg, then knit across the stitches of the second leg. You now have 84 (92, 100) stitches on your needle.
2. Work in stockinette stitch for 4 (5, 6) inches, ending with a WS row.
3. Shape armholes: On the next RS row, decrease 1 stitch at each end as follows: K2, SSK, knit to the last 4 stitches, K2tog, K2. You now have 82 (90, 98) stitches.
4. Work 3 rows even.
5. Repeat the decrease row every 4th row 2 more times. You now have 78 (86, 94) stitches.
6. Work even until the armhole measures 3 (3.5, 4) inches, ending with a WS row.
7. Shape neckline: On the next RS row, knit 18 (21, 24) stitches, bind off the next 42 (44, 46) stitches, then knit to the end of the row. You will now work each shoulder separately.
8. Left shoulder: Continue on the 18 (21, 24) stitches. Decrease 1 stitch at the neck edge every RS row 3 times as follows: on RS rows, K1, SSK, knit to end. You now have 15 (18, 21) stitches.
9. Work even until the armhole measures 4 (4.5, 5) inches. Bind off all stitches.
10. Right shoulder: Rejoin yarn to the remaining stitches with the WS facing. Work to match the left shoulder, decreasing at the neck edge with K2tog on RS rows. Bind off when armhole reaches the same length.

Bib (Knitted Separately)

The bib is the charming front panel that gives these overalls their distinctive look. It's worked in garter stitch with decorative buttonholes.

1. Cast on 24 (28, 32) stitches.
2. Work in garter stitch (knit every row) for 2 rows.
3. Row 3 (RS) – Buttonhole row: K2, YO, K2tog, knit to the last 4 stitches, K2tog, YO, K2. This creates a buttonhole at each end.
4. Work in stockinette stitch for 6 rows, ending with a WS row.
5. Next RS row – Buttonhole row: K2, YO, K2tog, knit to the last 4 stitches, K2tog, YO, K2.
6. Work 6 rows even in stockinette.
7. Repeat the buttonhole row once more.
8. Work 2 rows in garter stitch.
9. Bind off all stitches.

Finishing

This is where your romper comes together. Take your time with the finishing steps—they make all the difference in the final look.

1. Sew side seams of the body using a mattress stitch or whip stitch, matching the armhole openings.
2. Sew the crotch seam between the legs, joining the two leg pieces together.
3. Sew the bib to the front of the romper, aligning the buttonholes with the top edge of the body. Position the bib so it sits centered on the chest, covering the upper front area.
4. Crochet edging: Using the US E/4 (3.5 mm) crochet hook, work a round of single crochet around the armholes and neckline for a neat, finished edge. For a delicate shell stitch effect (as shown in the photo), work 5 double crochets into the same stitch, skip a stitch, and slip stitch into the next—repeat this pattern around the edges.
5. Attach buttons: Sew two wooden buttons to the back straps (or to the front bib, depending on your preference). If you're using the buttonholes on the bib, position the buttons on the back of the romper to align with the buttonholes when the straps cross over.
6. Weave in all ends with a tapestry needle, being careful to secure them well.
7. Block gently: Lay the romper flat, shape it to the correct measurements, and lightly steam or mist with water. Allow it to dry completely before gifting or using.

Straps (Optional)

If you prefer traditional straps over the buttoned bib style, here's an alternative:

1. Cast on 6 stitches.
2. Work in garter stitch (knit every row) until the strap measures 8 (9, 10) inches.
3. Bind off. Make 2 straps.
4. Sew the straps to the back of the romper and add buttons to the front bib for closure.

Tips for Success

• Check your gauge before starting—this is the most important step for a well-fitting garment.
• Use stitch markers to mark the decrease points for the armholes and the center of the neckline.
• Count your rows regularly to ensure your shaping is symmetrical.
• Choose soft, washable yarn—babies need comfort and easy care.
• Block your finished piece to even out stitches and give it a professional finish.
