Coolest Little Boo and Monsters Inc. Character Costumes

For several months we had friends telling us our daughter looks just like Boo from Monsters Inc. Then, I decided she would be Boo this Halloween and me and my husband would be her friends Sully and Mike. The first time she saw the costume she was terrified and she couldn’t even try it. Suddenly she changed her mind and loved to wear the costume. On the Halloween night she walked over 6 blocks in the treat or trick party from our city. We received lots of compliments and many people wanted to make pictures with us, OK I have to admit, with Boo. Everybody said she really looked like Boo.

I have not much experience with the sewing machine so I guess anybody with a sewing machine can do it. I found online ideas about how to make it and I added my personal touch. I used shinny purple (2 yards) and silver fabric (half a yard) from Hobby Lobby and used flannel (1 yard) for lining. To give the fluffy looking of the body I used three layers of batting in between the purple fabric and the flannel and sewed three lines horizontally.  I used a plastic ring from an old pop-up hamper to give the round shape to the body. I used Velcro to close the costume and to attach the hood. Eyes were made out of Styrofoam balls and pipe cleaners, teeth were made out of felt.

  1. Do you have a tutorial on how to make this? People tell us all the time that our daughter looks like Boo, as well. Her twin brother is going to be Sully!

  3. Can you share where you got the how to make info online? Or, are you willing to make it? Our daughter is in the same boat and is 19 months old. Would love to do the same thing you guys did. My email is pugsymalone@ymail.com thanks for sharing! Rupa

    • I layered 1 purple
      shinny fabric (35 in x 21 in), 3 layers of batting (33 in wide each x 20 in), 1
      layer of flannel for lining (33 in x 20 in). The extra inch in the purple
      fabric folds toward the interior (flannel) on both sides and the lower edge.

      Safety pin closed.

      Sew together all the sides but the upper. Then, sew three
      horizontal lines to give the quilted look. I used a plastic ring from an old
      pop-up hamper to give the round shape to the body. Put this ring on the upper
      edge and fold all 4 layers around and sew together. Roll the bodysuit into a
      tube and sew Velcro on both sides to close the tube according to the child’s

      For the armholes, cut out crescent shapes on each side at
      the same height. In my case I cut 3 in diameter circles, the center of the
      circles were 12 inches apart. For the sleeves I used silver shiny fabric lined
      with felt. I sewed by hand to the holes in the tube.

      For the hood I looked in internet instructions of how to
      make a hood. It was 9 in x 9 in with a outer layer of purple fabric, two layers
      of bathing and a inner layer of grey fabric. The outer layer was a little
      longer to fold over a wire (hanger) to keep the hood open. I put velcro on the
      upper edge of the tube to attach the hood.

      • Hi, you did an awesome job making those costumes! Can you tell me what kind of fabric you used to make the sully costume? Or where you got the fabric? I saw this photo on pinterest and am trying to make this for my daughter, husband and myself. Thanks for any advice!

      • I’m not sure what plastic ring you used from an old pop up hamper you are talking about. I’ve seen them being wire in those hampers. What size was the plastic ring? Did that go over her head?

      • Love it!!! Quick question, I’m unsure as to what plastic ring you are talking about from an old pop up hamper. I’ve seen them to be wire. How big was the ring? Was it big enough to go over her head? Thanks!

  4. When I saw this pic I had to do a double take! Our daughters could be twins! I thought I was looking at my little girl in a costume I never put her in! Oh my! The resemblance is scarey! I would love to send you a pic of my daughter! We live in Kentucky. She is 7 now. Please email me at jennyosborne73@gmail.com! Look forward to hearing from you!

  5. Hi! It seems that others have asked the same question. My daughter is 2 1/2 and I would love to have that costume. I’m just really bad at making them on my own and it is hard to find one like this in stores. Please email me if you are interested in making my daughter one for this year. Email at Randilynn.Cole@hotmail.com Thank you so much and hope to get a response. Have a good day.
