Make your own DIY LEGO costume with some cardboard, cups, and a little bit of spray paint. This is a great last minute costume idea – you probably have all the materials!
LEGO Block Costume
Since Jack was a baby, I have done matching costumes for our family. Some years are a little more extravagant (like last year’s Harry Potter costumes), and then there’s years like this where I wait until the last minute to put things together.
I honestly wasn’t even planning to do much of anything. There’s not a lot of Halloween festivities going on, and I’m just tired. But when it came down to it – even if the costumes are just for us, I felt it was worth doing.
My boys both got some LEGO costumes from the thrift store (sooo much cheaper than buying them new), so I decided that rest of us would be LEGO blocks. I mean, Andrew is one and doesn’t have an opinion on costumes yet, and it seemed simple enough for Forrest and me.
This is seriously the EASIEST costume to throw together – especially if you have lots of diaper boxes like us. I made all these in under an hour, and I had all the supplies laying around the house. I don’t know about you, but the less I have to spend, the better!
This makes for a great last minute costume or one that you’ve spent all month planning!
How to Make a LEGO Costume
Materials:
- Cardboard box (we used a large diaper box for Forrest and mine’s costumes and then a smaller box for Andrew’s. They were the PERFECT size!)
- Spray Paint
- Plastic cups (I used red solo cups for the adults and smaller, clear plastic cups for the baby)
- Ribbon
- Hot glue and hot glue gun
- Scissors or box cutter
Instructions:
Cut out the front for your LEGO box – rectangular is ideal. This is why I loved the diaper box – perfect shape!
Cut the bottom off of your plastic cup. I actually cut about half way up the cup and then trimmed the cup down. Otherwise, it’s too easy to just break the whole cup in half.
Hot glue the cups to the cardboard. I made the mistake of gluing them to the side with the pictures, rather than the plain side. Definitely use the plain side unless you want to use a lot of extra spray paint!
Spray paint everything – two coats is going to be ideal.
Hot glue the ribbon for hanging to the back.
Enjoy! Wear a matching colored shirt to make it look even better.

These turned out so cute! I never would have thought to use cups for the bumps on the LEGO bricks!

Great looking and easy to do costumes that every kid (including senior kids) can relate to. Legoland should see this post!
