Kids Halloween Costumes | DIY Scooby Doo and Shaggy

September 24, 2018

Halloween is slowly starting to creep up on us once again. I don't know if it's because I'm pregnant but I feel like I blinked and BAM a whole year just flew by and we will be welcoming a baby girl by the end of December! You all know that I love to DIY as much as possible with my kids halloween costumes (and who wants to spend $40-$50 on a costume that will only be worn for a few hours) not me! This year my kids started watching Scooby Doo so of course I came up with the idea of turning them into Shaggy and Scooby. 

Recreating this costume idea was easier than I expected. For the shaggy outfit, Giovanni already had those khaki pants so all I needed for him was a green t-shirt which I found at JCPenny for only five dollars. 

For the Scooby costume I was looking for a brown shirt and pants but came across this top and bottom at Target. The outfit came out under $20 and the good thing is he will be able to wear these pieces separetly this fall season! As you can see the only thing I had to make were the ears and collar which cost me a total of $2.60

Ears and Collar Steps & Supplies 

1 Cat ear headband 
4 Felt sheets (blue, yellow, brown, & beige)
Glue gun


I looked for an image of the collar online and started cutting pieces according to what I needed. I used the blue felt to cut out two 1 inch strips and one small diamond shape to fit on top of the yellow diamond shape I cut. I then cut out a very thin strip off the yellow felt to create a ring. Then just free cut the letters and glue everything together. 

(I did not glue the collar together until the day my son wore it because you need to make sure its loose enough not to be uncomfortable and I simply cut it off after he was done wearing it) You can always add a piece of velcro at the end for more use but I knew he would only wear it once so I chose not to do so.


The ears were just as simple to make as the collar. As you can see below I placed the cat ears on the felt and traced a shape that I thought was appropriate for Scooby's ears then cut out two pieces per ear. I placed one on top and one below and glued the front and back pieces together. Then I traced a smaller piece on the beige felt to go in the middle of the ear and voila, you have a dog headband! 

Again I found this cat ear headband in the Target dollar spot this year so I am sure they still have it :)

Mystery Machine Prop 

I ended up making them a prop of the Mystery Machine which in my opinion tied the whole costume together. You don't have to make one but if you decide to all you need is a foam board (dollar tree), paint, and an x-acto knife to cut out the window. I only had to buy the board because I had everything else. However if you choose to make it paint should only cost you about four dollars for the colors you need. I drew the design on the board with a pencil and then painted each section.

If you decide to recreate this costume idea I'd love to see how it turned out so make sure to tag me on Instagram here!
