Skill Level: Easy – Intermediate
Estimated Time: 4–6 hours (depending on your speed)
Size: 0–3 months

🧵 Materials Needed:

Yarn: Soft baby yarn (size 3 or light worsted weight) — approx. 200–250 yards
Hook: 4.0 mm (G-6) crochet hook
Tapestry needle (for weaving in ends)
Scissors
2 small buttons (for back closure)

📏 Measurements (approximate for 0–3 months):

Length: 12 inches (30.5 cm)

🪡 Stitches Used (US Terms):

CH – Chain
SC – Single Crochet
DC – Double Crochet
HDC – Half Double Crochet
SL ST – Slip Stitch
V-Stitch – (DC, CH 1, DC) in same stitch
Shell Stitch – 5 DC in same stitch

🧤 Step-by-Step Instructions:

🧩 Part 1: Yoke (Top Bodice)

Foundation:
- CH 60 (this will fit a 16″ chest; adjust in multiples of 10 if needed).
- Join with a SL ST to the first CH to form a ring (be careful not to twist it).
Round 1:
- CH 2 (counts as DC), DC in each CH around. Join with SL ST to top of CH 2.
- Total: 60 DC
Round 2 – Yoke Increase:
- CH 2, DC in next 9 STs, 2 DC in next ST; repeat * around. Join.
- Total: 66 DC
Round 3:
- CH 2, DC in next 10 STs, 2 DC in next ST; repeat * around. Join.
- Total: 72 DC
Rounds 4–5:
- Continue increasing similarly until you have about 84–90 DC.
- You want 4 points of increase for raglan sleeves if you prefer that shaping.

🧩 Part 2: Armhole Separation

Round 6:
- CH 2, DC in next 12 STs (front), CH 5 (armhole), skip next 18 STs (sleeve),
  DC in next 24 STs (back), CH 5, skip next 18 STs (other sleeve), DC in last 12 STs.
Round 7:
- CH 2, DC in every ST and CH space across — this forms the base of the skirt.

👗 Part 3: Skirt

Now that you’ve joined the sleeves, work on the skirt portion. You can customize this with different stitch patterns (shell, V-stitch, etc.).

Option A: Shell Stitch Skirt

Round 8:
- CH 2, skip 2 STs, 5 DC in next ST (shell), skip 2 STs, SC in next; repeat around.
Round 9–20:
- Repeat Round 8, placing shells into the center of each shell from the previous row.
- Continue until desired length (approx. 12 inches from shoulder).

🪡 Finishing:

Edging (optional):
- SC or picot edging around armholes and neck for a finished look.
Back Closure:
- Leave a small slit at the top back. Sew on 2 small buttons and use CH loops as buttonholes.
Weave in all ends using the tapestry needle.
