Our Experience Making A Homemade LEGO Costume
We try to make the kids costumes each Halloween. This year, Lowes inspired us to “think outside the box” and with the help of a giant appliance box (Thank you handy shopping assistant Doug!!) and a couple of cans of spray paint as well as several smaller boxes we had Legos. Human Legos.
Lego blocks are one of our favorite things to play with. All. Day. Long. The kids absolutely love building and creating.
Red is my son’s favorite color. He’s thrilled with his costume – and I was thrilled with how easy it was to create. All it took was a short trip to my local Lowes.
LEGO Costume Is Perfect In A Pinch
These LEGO brick costumes are some of my most favorite homemade Halloween costume because they’re simple and easy to make in a pinch. And there are many different ways to make these LEGO bricks, but this is the easiest costume to me. This can also be a family costume!
Simple arm holes, favorite colors, cardboard…it’s awesome and one of the best costume ideas. It can be kid costumes or adult LEGO costumes, regardless they’re perfect for Halloween night.

Love the LEGO… tried to talk my son into that a few years ago. He is always coming up with super creative there’s no way you could buy it if you wanted to costumes… This year, he wanted to be a sloth bear! I blogged about it here: http://www.childcentralstation.com/2011/10/sloth-bear-costume.html and you can see more photos here: http://www.facebook.com/media/set/?set=a.807762316087.2249106.40608739&type=1&l=5bec297ca8

Very creative idea! Love it, love it, love it…
Here’s what my son will be sporting this weekend…
I LOVE the Lego costumes! So great. This year my daughter is going to be Rogue from X-Men, but last year we dressed up as a family: Mario, Luigi and Toad. Here’s a picture: http://franticallysimple.com/2010/10/30/happy-halluigi/
Like a previous comment, one year I wrapped a large box in birthday wrapping paper and went as a birthday present including a large bow on my head with lots of curly ribbons. The next year, my sister turned the present box into a Sponge Bob Square Pants and I went as Patrick (We taught kindergarten at the same school and wanted to have costumes that “went” together.) I have to say, it’s difficult to function while wearing a large box!
My absolute favorite costume was the year that my mom made my 2 year old son a monkey costume and my husband created a “man in the yellow hat” costume. We used a basket wrapped in yellow duct tape and a cardboard circle painted yellow to make the hat. We dyed a white shirt and white pants yellow and even made the polka dot tie. My husband is 6′ 4″ with dark brown hair, so they made the perfect Curious George and man with the yellow hat.
Last year we dressed my husband up as a dead miss pageant winner he looked so great he wore fingernails heels/makeup it all… he looked hilarious!
The Lego idea is awesome! I may have to keep that in mind for next year 🙂
Eli’s costume this year is “Rocket Man”, as he calls it. I found an awesome tutorial for a jet pack on Pinterest, and that is the foundation of his costume. http://pinterest.com/pin/285325884/
To complete his costume I embellished some grey pants and a grey shirt with shiny duct tape. He loves it and we got tons of compliments on it at a costume parade that we attended today! https://www.facebook.com/photo.php?fbid=521495882029&set=a.520241745329.2014010.111800877&type=3&theater
I LOVE the lego costume! The long brick and short brick. That is too cute! We always make R’s costumes as well. My favorites where when he was Squirtle from Pokemon (my husband use to love pokemon.. lol.. husbands) and last year’s when he was a pterodactyl. Here’s last years..

This year he wants to be a cat. I still haven’t made it though. Isn’t that horrible? I never learn.
