Homemade Lego Costume

Sharing is caring!

Are you making Halloween costumes at home this year? Don’t you miss doing this as a kid? I remember my mother making ours for many years of our childhood.

I have the simplest tutorial  for making a homemade Lego costume.  This literally can be made in about 30 minutes and costs next to nothing.

I am not sure if you remember or not, but last year we shared 31 days of easy DIY Halloween costumes from other bloggers all over the internet. It was such a fun way to share simple costume ideas with other moms. Ever since then I have wanted to make a Lego costume for my boys.

Let me show you how simple this was.

(I do not have pictures of us making this during the process because we did it in a hurry after getting an invite to a local morning show segment to talk about DIY Halloween costumes. But this is an easy one. )


Take a regular large box (we used one that large air conditioning filters come on) and stand it up in a vertical position.

Cut the back off of the box with scissors  or an xacto knife.

Then cut a half moon shaped opening out of the top and bottom of the box as shown below so that the child has a place to step into the box.

Cut arm holes out of the box.

At this point we applied a layer of red spray paint evenly over the box.

We (ok, my husband)  also lined up 8 clear disposable drinking cups. Spray paint them as well.

Once they are dry, cut them down to about 1/2 the size salvaging the bottom portion of each cup to glue onto the box.

Line the cups up and hot glue them, bottom end of the cup facing out, to the box. Do this in four rows of two cups.

Now, spray another even layer of paint onto the box and the cups for an even look.

Let it dry 100% before letting a child use it.

Your kiddo can easily step into the box and place his or her arms through the arm holes.

I had our son wear a red thermal shirt, since the Lego is red.

Black jeans and regular play shoes went along perfectly.

This is how the costume looks from the back when the child is in the box.

This literally costs nothing to make.

It is super light and easy for your kiddo to wear.
