How to make a doll dress

1. Materials & tools

Materials (27 cm doll)

• Main fabric (lawn, broadcloth or double gauze — something thin) — about 40 × 30 cm (16 × 12 in)
• Tiny snap fasteners or narrow hook-and-loop — 2–3 sets
• Narrow bias tape (about 6 mm / ¼ in finished) — about 60 cm (24 in)
• Optional: narrow lace or ribbon

Tools

• Sewing machine (or needle and thread)
• Fabric marker or pencil
• Ruler and scissors
• Iron
• Pins or clips

2. Make the pattern (auto-generated in Katagami)

With the Katagami pattern tool, you just enter the finished size and it drafts a seam-allowance-included pattern, tiled to print at actual size on Letter or A4.

1. Open the tool
   Open the pattern tool and choose “Accessories” → “Doll dress” from the tabs at the top.
2. Enter the size
   Enter the doll's chest, length, shoulder width, hem flare and ease. Presets cover 20 cm, 27 cm and 40 cm dolls.
3. Set the seam allowance
   Use the slider at the bottom (beginners: 1.0–1.5 cm / about 3/8–5/8 in).
4. Print
   Press “Print (actual size)”, then in the print dialog set Scale = 100% and turn “Fit to page” OFF. Check the 50 mm calibration box on the first guide sheet with a ruler.

3. Cutting the fabric

1. Trace the pattern
   Use a mechanical pencil rather than chalk — a thick chalk line is a 1–2 mm error at this scale.
2. Cut
   Cut one front on the fold and a left and right back. Each back has an overlap beyond the center back for the snaps.
3. Finish the edges
   Seam allowances are 5 mm, so pinking shears are more manageable than a zigzag.

4. Sewing

4-1. Sew the shoulders

1. Place front and backs right sides together and sew both shoulder seams with a 5 mm allowance.
2. Press the allowances to one side rather than open — at this scale, pressing open adds visible bulk.

4-2. Finish the back opening

1. Each back has an overlap beyond the center back for the snaps. Turn that edge under twice — 5 mm and 5 mm — and stitch.
2. Doing this before the neckline lets you tuck the ends of the neckline binding in neatly.

4-3. Bind the neckline and armholes

1. Sew narrow bias tape around the neckline, turn it to the inside and topstitch. Fold each end of the tape in by 1 cm at the back opening.
2. Bind the armholes the same way.
3. Wide tape will not follow a doll-sized neckline. Use narrow tape, or cut your own bias strips from the main fabric.

4-4. Sew the sides

1. Sew both side seams from the underarm to the hem, backstitching at the underarm.

4-5. Hem and fit the snaps

1. Turn the hem under twice — 5 mm and 5 mm — easing the flare in as you fold, and stitch.
2. Lap the right back over the left with the center-back marks together. Fit two or three snaps, or narrow hook-and-loop, on the overlap.

✏️ Two things decide whether doll clothes look right: a 5 mm seam allowance and thin fabric. A standard 1 cm allowance makes the side seams so bulky the dress will not go on.

5. Tips & variations

• Hook-and-loop is easier: much simpler for a child to manage than tiny snaps.
• Small prints only: a large print puts no complete motif on a garment this size.
• Practice piece: bias-bound necklines and flared hems, in miniature and using almost no fabric.
