Giggles Galore Handmade DIY Octopus Costume

I love homemade costumes and this DIY Octopus Costume is all kinds of fabulous!  Did I mention it’s no sew, quick and affordable?

I’ll admit, I’m somewhat of a costume snob.  So when the Hub Network asked me to share a DIY costume for kids I was thrilled.  You see I have a really hard time buying those cheap’o polyester costumes at the big box costume stores and I am sure I have my super creative mother and even grandmother to thank for it.  I remember having some of the coolest costumes as a kid, my mom would tell you we had homemade costume because she was frugal but I still remember that cute little pumpkin costume and who could forget the year I went as Pippi Longstocking!  While brainstorming ideas with my mom she mentioned that one of her favorite Halloween costumes was the year she was an octopus.  Bingo. I decided to recreate that costume idea for my ocean loving daughter.

DIY Octopus Costume Giggles Galore

This easy handmade costume took me less than hour to put together.  Here is how I created this sassy sea creature:


    • 4 pairs of tights in your daughter’s size 
    • Matching long sleeve shirt
    • Matching hat
    • Belt
    • White and black felt
    • Cotton Batting

**I purchased the tights, shirt and hat from Old Navy for $30 and once Halloween is over she’ll have a new outfit to wear!**

1. Begin stuffing 3 pairs of the tights with cotton batting.  I learned that you want to stuff them to just above the crotch area of the tights, that will give the the fullest look and it won’t bunch in that area when you put them on the belt.

2. Next, lay your belt flat and begin wrapping the top part of the tights around the belt.  Secure in place with a safety pin.

3. Cut out two large ovals and two small circles for the eyes.  Use double stick tape or glue to attach them to the hat.  **I used double stick tape since this is a hat my daughter will wear again and we didn’t want to ruin it.

4. Have your daughter put on the unstuffed pair of tights and the coordinating long sleeve shirt.  Wrap the belt with the stuffed tights around her waist and fasten.

5. Put on the hat to complete the costume.

There you have it a super easy, sassy DIY Octopus Costume that is sure to be the talk of the “ocean!”

  9. This is the cutest costume I think I’ve ever seen. I just love it! 🙂

  10. What a cute idea! I must confess when I first saw this I thought there was no way I could put together something like this. But your easy insructions you may have me looking like the “cool” Mom at this years Halloween parade afterall. 🙂 Thanks for sharing!

  11. O saw that and said “OH that’s SO CUTE” about 10 seconds later “HEY I know her!”


    ADORABLE! You are so talented, girl!

  12. Super cute — my daughter wants me to make her one for this year. After last year’s peacock, I think this looks much simpler and far less time consuming! Do you recall how much cotton batting you had to purchase? Is it in bags or by the foot? And did you get it at Michael’s or JoAnn’s? Thanks!

    • Thanks! My other daughter loves peacocks, I bet that costume was adorable! I used 1 big bag of cotton batting and purchased it from Hobby Lobby. I would suggest finding it at JoAnn’s though since I know they sell it for sure. Good luck with the costume, and of course send us pictures if you do make it! 🙂

      • Thanks for responding! I will post a pic if I can convince my daughter that she does NOT want to be a “sea monster” after all….wish me luck! I don’t even know what a sea monster looks like! Plus, I do NOT sew, so if I cannot glue-gun it, which typically results in 3rd degree burns and subsequent scarring, or Superglue it (resulting in fused fingers and/or adherence to whatever it is I’m making), then I cannot accomplish it!!!

      • Turns out that I am going to be the octopus! My one daughter is a jellyfish (super cute!) and the other is a dolphin. The dog is a sea monster, so it made sense that I be the octopus, since it’s so cute and I couldn’t talk one of them into it! Perhaps I’ll save it and one of them will want to use it next year?!

  13. Love this costume. I am looking for ideas for me to take the kids trick or treating. I think something like this will be simple but cute for walking around.
