Alice in Wonderland is one of the most popular stories in English fiction. She has wild adventures and meets a crazy cast of characters. If you’ve been thinking of what to dress up as for Halloween, how about her? Here’s an easy Alice in Wonderland blue dress DIY you can whip up in less than a day!

I also made an Alice in Wonderland apron for this costume, so be sure to check out that tutorial too.

Tools and materials:

  • Pale blue fabric - 1 yard
  • White fabric for trim
  • Your own sleeveless dress for a pattern
  • Elastic
  • Needle and thread
  • Sewing machine
  • Paper
  • Pen
  • Marking chalk
  • Measuring tape
  • Pins
Running a basting stitch along the skirt

1. Make the skirt

Cut a piece of blue fabric that measures your bust size plus ½ an inch seam allowance, by the length you want the skirt. For me, that measurement is 62 x 23 inches. Hand baste the top of the skirt fabric to create gathers.

Set aside for now.

Folding the fabric in half to make the bodice

2. Make the bodice

Fold the rest of your fabric in half. 

Tracing an existing dress to make the bodice

Lay your own sleeveless dress folded in half lengthwise on top to serve as a pattern. Trace the outline on a piece of paper. The side will be straight and not curved because we are going to add elastic to gather it at the waist.

Cutting the fabric for the bodice

Add a ½-inch seam allowance. Cut the folded fabric.

Cutting the back bodice piece

Use the front cut piece as a pattern for the back. Lay it on top of another piece of folded fabric. The back neckline is higher and the armhole is smaller than the front.

3. Sew the top

Pin both shoulders and one side seam. Sew them with a straight stitch on the sewing machine.

Tracing the back neckline to make the collar

4. Make the collar pattern

Trace half of the back neckline and half of the front neckline on paper to make a Peter Pan collar. 

Alice in Wonderland dress pattern

Draw the collar as a half of a round circle with a vertical line in the center. One end should be curved in a half-moon shape and the other should be straight.

This pattern will be cut twice.

Attaching the bodice to the skirt

5. Attach the bodice to the skirt

Pin the bodice to the skirt. Sew them together on the wrong side using a straight stitch. 

Measuring elastic for the waistband

6. Make the waistband

Measure a piece of elastic to fit your waist snugly. 

Pinning and sewing the waist elastic

Pin the elastic and then sew it directly to the wrong side of the dress.

Marking fabric for the dress sleeves

7. Make the sleeves

Puffed sleeves are wider than normal sleeves. 

Fold the fabric in half. Then fold it in half again. Draw a curved ruffle. Watch the video from 3:42-3:55 to see the shape.

Cutting out the sleeves

Cut the fabric as marked.

Hand sew the straight edge to ruche or pleat it in. 

Adding white fabric for the sleeve cuffs

8. Make the cuffs

Sew down one edge of a piece of white fabric at the gathered end of the sleeve.

Then, fold the fabric over to form a white border at the edge of the sleeve. Pin into place.

Sew the white border down at the very edge.

Pinning the sleeves to the armholes

9. Attach the sleeve

Fold the sleeve in half and tuck it into the dress. Have the white band inside and the raw edge at the armhole. Line up at the side seams and armhole seams. Pin at the bottom to secure it. 

Sewing the sleeves on the dress

Tuck in a few pleats at the top as the sleeve is bigger than the armhole. Sew them together on the wrong side. 

Making the collar for the dress

10. Make the collar

Cut out the 2 pieces in both blue and white fabric using the collar pattern, with a ½-inch seam allowance. 

Cutting snips in the collar so it lays flat

Sew only the outer edge together on the wrong side. On the seam allowance, cut tiny snips so it lays perfectly flat when it’s turned inside out. Turn the collar inside out.

Pinning the collar to the dress

11. Attach the collar

Attach the collar to the dress by pinning, then sew it with the white underneath and the blue on top. You’re done!
