This homemade costume for women entered our 2013 Halloween Costume Contest.

A word from Sarah, the 'Dory' costume creator:

I'm wearing the costume, inspired from Pixar's Finding Nemo. Dory has always been my favorite animated character, and I decided to become her for Halloween.

How to make Dory instructions:


  1. Using balloons create the underlying structure of Dory's face. I used a combination of regular balloons and long balloons and taped them together to a large piece of cardboard.
  2. Use paper mache to coat the balloons. I used a paste of boiled water with flour and strips of newspaper. Typically you want to get 10-15 layers of paper over the balloons. It is best if you can allow a few days of drying time between each layer.
  3. Allow a week or more for the paper mache to completely dry.
  4. Pop the balloons from the back and remove the debris
  5. Paint Dory's face using a photo as a guide. I used acrylics and found a metallic paint that helped bring more of a sheen to Dory's face.
  6. Optional: Apply a spray sealant over the dry and complete head to better preserve it.


  1. Obtain the following: blue fabric, yellow fabric, black fabric paint
  2. Cut 4 large tear drop shaped pieces of fabric out of the blue fabric. Cut out a small hole in the middle to make an arm hole.
  3. Sew 2 pieces together outsides facing in. Do the same with the other two pieces.
  4. After sewing inside out, flip right-side-out and stuff with pillow stuffing (just a bit so there is still flexibility)
  5. Cut a strip of fabric to connect the two pieces together in the back and another strip to connect in the front
  6. Finish stuffing as desired
  7. Using fabric paint and a picture as a guide, paint the traditional Blue Tang markings
  8. Make fins and attach to body
  9. Optional: add magnets so fins can be tacked to Dory's body or to your arms by wearing bracelets with magnets attached

#4 comment by Lexie October 4, 2015

If you are looking to sell this costume, I would love to purchase it.

#5 comment by Sarah October 4, 2015

The entire head (including eyes) were made out of paper mache and then painted.

Unfortunately, this costume is not for sale. In the future, I may consider making replicas in requested sizes. Thanks for your interest!

Wow it looks amazing

#9 comment by michele November 3, 2016

I would love to know how the head was attached since our hospital is doing Dory and Nemo for our Christmas parade float.

The head had elastic straps that allowed me to put it on first like wearing a backpack on your front. Then I put on the body and tucked it into the head.
