Photo Diary: Making a Wonder Woman Costume

How I Made a Wonder Woman Costume

Halloween Costume | Wonder Woman!

Back in July, my friend Gina asked me if I would make her a Wonder Woman costume for Halloween. She showed me pictures of costumes she liked (especially this one) and added a couple of requests (like a headband), and I took it from there!

I designed the costume myself, but I hadn’t actually seen the movie. So I did a lot of Googling. The image results for Wonder Woman were pretty much permanently open in my browser. πŸ™‚

As you’d expect, there was some trial and error (especially with the W belt), but 80% of the time, I was super impressed with myself. The other 20% of the time, I was annoyed. Or dejected. (“Whyyyyyy won’t it work??”)

Here are the pictures I took along the way!

If You Want to Make Your Own …

Here’s an overview of what I did!



This is basically a fit and flare dress with princess seams on the top. You can either make your own pattern or find a good pattern for a fit and flare dressΒ andΒ a pair of shorts.

Note: You’ll see that I go back and forth a lot — drawing patterns, cutting fabric, sewing, etc. That’s what worked best for me here, so that’s what I did!

The Top

1) Take a basic pattern for a fitted dress top and cut it so that it has a sweetheart neckline in front.

2) Save the top of the pattern (neckline to shoulders) and use that as the pattern for the illusion neckline.

3) Add princess seams to the bodice pattern (if they don’t already exist) and cut the pieces out of the red fabric. (If you’re making/enhancing a pattern remember to add seam allowances for the princess seams! I forgot that part when I made the mock-up …)

4) Sew the front and back pieces together at the princess seams. But don’tΒ sew the side seams or the center back.

5) Cut the shoulder pieces out of the tulle and sew them to the bodice pieces. Note: Since you’re sewing two curves, it’s going to seem a bit weird. But it looks really nice when the seam is done!

6) Trace the sweetheart neckline, measure down two inches, and trace the neckline again. Then, add a triangle/bird head in the middle. Cut 1 out of gold fabric . This will be the gold enhancement for the front.

7) Measure the length of your back pieces (from the side seam to the center back) excluding the seam allowances for the princess seams. Draw a piece that’s this length and 2″ tall. Cut 2 out of gold fabric. This will be the gold enhancement for the back.7)

8) Sew the gold pieces on top of the bodice. The gold edge should fall right where the red and tulle meet.

9) Sew the side seams and shoulder seams.

The Skirt

10) Cut out an A-line skirt that is about 13″ from waist to hem. For reference, Gina is 5′ 3″, so a 22″ skirt would be about knee length. [Use the blue fabric here.]

11) Make a mark every 3″ around the skirt. Then draw a horizontal line 3″ down from the waist. Cut a straight vertical line at every mark, starting at the hem and stopping at the horizontal line you drew. These are the pleats for your skirt. Note: The cosplay fabric I used didn’t fray, so I didn’t need to finish the sides or the hem. I recommend finding fabric like this!

12) Use the top of the skirt pattern to draw a blue “belt” pattern to go on top of the skirt. My belt was 3″ at its shortest, and it came down in two points to make a W shape. Cut one on a fold for the front; cut two for the back.

13) Shorten the blue “belt” pattern by 1″ and cut it out of gold fabric. Then cut two triangles out of the front waistline to make a true W. (Leave the back in triangles.)

14) Cut another W — roughly 1 1/2″ thick — out of the gold fabric.

15) Layer the “belt” pieces on top of each other — blue trianges, gold W, second gold W — and be sure to stagger the gold pieces so that they overlap slightly. Stitch the gold fabric down.

16) Baste the “belt” to the skirt.

The Finishing Touches

17) Sew the top to the skirt.

18) Cut an extra triangle of gold fabric and sew it onto your existing gold Ws. (This makes a true W shape — it just didn’t look right without the point!)

19) Cut two 1″ wide strips of gold fabric that go from the center back to the side of your W.

20) Sew the extra gold pieces in place and stitch all around the waistline (about 1/4″ from the seam).

21) Sew in your invisible zipper.

22) Made a very short pair of shorts to go under the skirt. [Use the blue fabric here.]

23) Cut two gold rectangles (both on the fold) that are 3 1/2″ x 5″ x 4 1/2″ x 5″ (that last side will be a diagonal). Stitch the long ends of each rectangle together to form a tube. These are your wrist guards. (I was foolish and didn’t cut these on a fold. Which means I had two seams on each wrist guard. But that works, too!)

24) Draw a 1″ x 6″ rectangle and add a (half) triangle that extends down another 3/4″. (My triangle was 1″ across x 1 3/4″ down x 2″ hypotenuse.) This will be the bottom piece of your headband.

25) Draw another rectangle — this one 1/2″ x 6″ — and add a triangle that extends down another 1″. (Total dimensions: 1″ across x 1 1/2″ down x 1 3/4″ hypotenuse) Then cut off the inner corner of the triangle so you have a shape that basically looks like this (when you turn it on its side). This will be the top piece of your headband.

26) For each piece, cut one (on fold) of gold fabric and one (on fold) of interfacing (if you have it. If not, no big deal). Iron on interfacing.

27) Layer the pieces on top of each other and stitch.

28) Cut a piece of elastic to fit around the rest of your head (probably about 13″). Sew the ends of the elastic to the ends of the gold.

Phew. You’re done!
