What You’ll Need

Yarn:

• Type: Soft, baby-safe yarn (acrylic, cotton, or bamboo)

• Weight: Light Worsted (Category 3) or DK (Double Knitting)

• Amount: 250–350 yards for 0–6 month size

Tools:

• Tapestry needle (for weaving in ends)

• Stitch markers (optional)

• Buttons or snaps (for closure, 2–4 pieces)

• Scissors

• Measuring tape

Sizing Chart

The instructions below are for 0–6 months. For other sizes, increase chains and rows accordingly.

Basic Stitches Used

This pattern uses simple, common stitches:

• ch – chain

• sl st – slip stitch

• sc – single crochet

• hdc – half double crochet

• dc – double crochet

• inc – increase (2 stitches in one stitch)

• dec – decrease (crochet two stitches together)

If you’re new to any of these, practice on a small swatch first.

Construction Overview

The romper is made top-down in one piece:

1. Start at the yoke (chest/shoulder area)

2. Work downward to form the body

3. Split the bottom into leg openings

4. Add straps and buttons

This method avoids seams and makes it easy to adjust as you go.

Step-by-Step: Easy Crochet Baby Romper (0–6 Months)

Step 1: Make the Yoke (Top Section)

1. Foundation Chain

   • Ch 60 (adjust in multiples of 4 for other sizes)

   • Join with a sl st to form a circle (ensure the chain isn’t twisted)

2. Rounds 1–4 (Establishing Ribbing)

   • Ch 2 (doesn’t count as dc), dc in each stitch around

   • Sl st to join

   • Repeat for 3 more rounds (total of 4 dc rounds)

3. Optional: Add Ribbing Texture

   • For extra texture, alternate fpdc (front post double crochet) and bpdc (back post double crochet) in Round 4

✂️ Step 2: Body of the Romper

Now we start working downward from the chest.

1. Rounds 5–15 (or until desired torso length)

   • Ch 2, dc in each stitch around

   • Increase slightly every 2–3 rows (e.g., add 4 extra stitches evenly spaced)

2. Optional:

   • Add stripes or stitch variations (shell stitch, V-stitch, or mesh)

Length tip: Stop when the piece measures about 9–10” from shoulder to crotch.

Step 3: Split for Leg Openings

Now you’ll divide the tube into two legs.

1. Divide Stitches in Half

   • Count stitches and split in two (e.g., 66 stitches = 33 per leg)

   • Attach a stitch marker to mark the front/back

2. First Leg

   • Join yarn at center crotch

   • Dc around half the stitches

   • Join with sl st

   • Work 3–5 more rounds for leg length

   • Optional: Add ribbing (fpdc/bpdc) or sc edging

3. Second Leg

   • Repeat on the other half

Step 4: Bottom Closure (Optional)

To make changing easier, many rompers have button or snap closures at the crotch.

• After finishing both legs, use sc to create a band across the crotch front and back

• Add 2–3 buttonholes on the front band and sew buttons to the back

• Or sew in plastic snaps

Step 5: Add Straps

1. Mark Placement

   • Try folding the romper flat to find strap positions

   • Mark where you want the front of each strap to start (usually just beside each shoulder)

2. Make Each Strap

   • Join yarn and ch 20–25 (adjust for baby’s shoulder length)

   • Turn and sc back down the chain

   • Attach to the back panel (or make buttonholes to create adjustable straps)

3. Sew Buttons on the Back or use snaps to close the straps

Step 6: Finishing Touches

• Edging: Use sc or decorative stitches around neck, arms, and legs for a clean finish

• Weave in all yarn ends with a tapestry needle

• Steam block (optional) to shape and soften

Design Variations

Once you’ve mastered the basic romper, here are some fun ways to customize:

Color Options:

• Stripes

• Ombre / Gradient yarn

• Color-block top and bottom

Stitch Ideas:

• Shell stitch skirt attached at the waist for a romper-dress hybrid

• Puff stitches or bobbles for texture

• Lacy stitches for summer versions

Embellishments:

• Appliqués (hearts, stars, animals)

• Crochet ruffles on the straps or bum area

• Add pockets

Washing Instructions

Always check the yarn label, but general care for baby garments:

• Machine wash on gentle

• Cold or warm water

• Mild detergent

• Lay flat to dry or tumble dry on low (if yarn allows)
