There’s something timeless about an A‑line dress with a crisp inverted pleat—clean lines, a little swing, and just enough structure to feel “special.” This tutorial walks you through sewing a simple, sleeveless A‑line dress with an inverted front pleat for 18‑inch dolls (such as American Girl®), including fabric requirements, free PDF sewing pattern, and step‑by‑step instructions.
You’re welcome to use this pattern for personal sewing and gifts.
Fabric requirements
For one sleeveless A‑line dress (18‑inch doll):
Main fabric:
Amount: ⅓ yard (30 cm) of 44/45" wide woven
Closure:
Option 1: 4–5 small sew‑on snaps
Option 2: 4–5" strip of hook‑and‑loop tape
Notions & tools:
Thread: All‑purpose polyester or cotton
Marking tools: Fabric pen/chalk
Pins or clips
Iron & pressing surface
Paper & printer (to print the PDF pattern once you lay it out)
Fabric suggestions
For a neat inverted pleat and crisp A‑line shape, choose light to medium‑weight woven fabrics:
Best choices:
Quilting cotton
Cotton poplin
Cotton lawn or voile (for a softer drape)
Also suitable:
Lightweight linen or linen‑blend
Cotton sateen (for a slightly dressier look)
Avoid:
Stretch knits, jersey, heavy denim, thick canvas—these will distort the pleat or feel bulky on a small doll.
You can use a contrast fabric for the pleat underlay or the neckline facing to add a little surprise when the pleat opens.

Step‑by‑step sewing tutorial
Step 1: Cut the paper pattern pieces out from the pattern pdf pages
Step 2: Cut out the pattern pieces from the fabric.
Step 3: Prepare the inverted front pleat
Mark the pleat lines
Transfer the markings for center front and lines A1 and A2 from the pattern for the left and right sides.
On the frontpiece, mark the center front. Fold the pleats. Fold and press the A1 pleat lines on the right (or good) side of the fabric.
With all the pleats folded and pressed, it should look like this:
Now, bring the outer pleat line (A1 pleat line) toward the center front line so the fabric folds under itself. Pin the fold in place.
Press the folds sharply with an iron.
Fold and press the A2 pleat lines on the wrong side of the fabric.Secure the pleat at the top
Stitch across the top of the pleat within the seam allowance (about ¼" from the raw edge) to hold it in place.
Optionally, baste down the pleat for 1–1½" from the waist to keep it crisp while you sew.
Step 4: Serge the raw shoulder seams and side seams
Place front bodice and back bodice pieces right sides together.
Sew the shoulder seams with a ¼" seam allowance.
Open the seams and press.
Step 7: Armholes

With right sides together, sew the side seams of the bodice using a 1/2 inch seam allowance.
Now fold the bias tape to the wrong side and hem it in place. I hemmed it by hand for a neat finish. Also, it is easier to sew by hand than by using the sewing machine, as the armhole round is small.

Step 8: Fold the button plackets at the back
Turn under ¼" along each center back edge; press.
Turn under another ¼" and stitch to create a neat placket. Press well.
Now turn the folds to the right side and press well.
Step 9: Sew the neckline
Measure around the neckline. Take a bias strip that is equal to the this measurement. Fold the bias tape in half.
Step 10: Hem the
dress
Turn up hem
Fold ¼" at the bottom edge of the skirt to the wrong side;
press.
Fold another ¼" and stitch closer
to the folded edge.
Step 11: Add
closure
Hook‑and‑loop:
Sew one side to the
inside of the left back, the other side to the outside of the right back.
Snaps:
Sew 4–5 small snaps
evenly spaced from neckline to the hemline.
Step 12: Final
press
Press the inverted
pleat so it lies flat and crisp.
Give the whole dress a
gentle press for a polished finish.
Optional design variations
Add Collars
Sew decorative buttons
Decorative topstitching:
Add a line of stitching down each pleat fold for a tailored look.
Trim at hem or neckline:
Add lace, rickrack, or piping for a vintage feel.
