Crochet hook: Size appropriate for your yarn (usually G/4.0 mm or H/5.0 mm).

Chain (ch)
Single crochet (sc)
Half double crochet (hdc)
Double crochet (dc)
Slip stitch (sl st)
Increase (2 sc in one stitch)
Decrease (sc2tog – single crochet two stitches together)

🧷 Basic Pattern Overview

1. Create the Bodice (Top Part)

Back Panel:

Chain enough stitches to measure the width of the back (e.g., 40–50 ch for a 0–3 mo size).
Row 1: Work 1 hdc in 2nd ch from hook and across. Ch 1, turn.
Rows 2–10: Continue working hdc rows. Adjust number of rows based on desired bodice length.
Fasten off and set aside.

Front Panel:

Same as back panel. If desired, leave a neck opening (divide the last few rows into two parts and work each side separately).

2. Join at the Shoulders

Use slip stitch or sew together 5–8 stitches on each shoulder side, leaving a gap in the middle for the neck.

3. Make Armholes

Attach yarn to underarm edge and crochet in rounds around the armhole with hdc or sc stitches.
Do 5–8 rounds or until desired sleeve length.
Optional: Make sleeves long by continuing rows.

4. Crochet the Bottom Half

From the bottom edge of the bodice:

Attach yarn and work in rounds or rows, increasing slightly at the hips.
Continue working downward in dc or hdc until reaching the crotch level.
Divide the piece into two leg openings.

5. Make the Leg Openings

Work each leg separately in rounds.
Add a few rounds of sc or ribbing (front post/back post dc) for the cuffs.
Fasten off and repeat for the other leg.

6. Add Button Flap or Snap Closures

You can add a button band at the crotch for easy diaper changes:
- Leave the bottom center open.
- Crochet a short flap (e.g., 5–6 rows) on one side, and add buttonholes.
- Sew buttons on the other side.

7. Finishing Touches

Weave in all ends with a tapestry needle.
Add decorative edging (optional) with a contrasting color.
Sew on any embellishments (like a small bow, applique, or ears for a hooded version).
