DIY Lord Business Costume

LB - Header Horizontal

In mid September, my wife asked the kids what they wanted to be for Halloween and my son was having a hard time coming up with something.  An idea popped into my head and I suggested to him that he could be “Lord Business” from the Lego movie.  His eyes immediately lit up.  A quick search turned up absolutely no results for Lord Business kid costumes.  My son had already set his heart on the idea, so we had no choice but to make the costume ourselves.  Boy… is this a slippery slope!

I had heard the term “cosplay” before, but had NO IDEA how intense and creative this hobby could be.  After doing (far too much) research on costume making, I decided my son and I could take on this project and have a bunch of fun doing it.  I didn’t have a lot of time to order materials, so I had to improvise on a few things.  Luckily, at work we were going through a big cleanup of our facilities so I was able to get most of my materials from stuff that was destined to be thrown out.  Mainly cardboard boxes and foam.

Materials List:

  • Scavenged Foam + Additional Foam Roll from Wal-Mart
  • Cardboard
  • 3M 77 Spray
  • Hot glue gun
  • Sandpaper (various grits)
  • Paintable Caulk
  • Rustoleum FlexiDip Spray Paint
  • Utility Knife
  • Sharpie
  • Electric Carving Knife
  • Scroll Saw (optional, but it helps)


I should mention that I didn’t have any template to work from.  However, I did find some 3D models someone had made of the shoulder pads and helmet.  I downloaded those files and used this website to view them.   This made a huge difference in how accurate I could get with the dimensions of the costume.

I should also mention that the Wal-Mart poly foam (used for seat cushions etc.) was not very dense, which made it much more difficult to cut and sculp.  My scavenged foam was pretty dense and made cutting and sanding a lot easier.

Shoulder Pads

I wanted the shoulder pads to be more rigid, so I decided to use cardboard as a base layer with foam on top of the cardboard to give it dimension.  I used my tape measure to take some quick/rough measurements of my son from the top of his shoulders to the middle of his chest, as well as how wide and deep his head was.  I almost screwed up by making the opening of the shoulder pads too small, which would have meant he couldn’t get it over his head!  Using a straight edge, tape measure and a utility knife…. I laid out my template and made my cuts, including cut outs for the tie.

One little trick I used to get the cardboard to bend consistently and straight was to flip over the cardboard and carefully cut out a “V” along the bend line without puncturing all the way through the cardboard.  This made the cardboard bend in a straight line without wrinkling.

After cutting all my foam pieces and glueing them to the cardboard, I used the black FlexiDip to paint the whole shoulder pad piece.  I also decided to replace the cardboard tie with a foam tie so that I could bevel the edges.  The red FlexiDip covered the tie pretty well because the foam was white.

Finally, I used a hot glue gun to attach the tie pieces to the shoulder pads and then added some elastic (not pictured) to help keep them in place.

I can’t take much credit for the cape.  My wife has developed some sewing skills over the past couple years and volunteered to help.  She found a cheap, red Wal-Mart bed sheet to use.  Because the actual lego cape is stiff, she sewed two pieces together so we could fill it with foam (to keep it stiff) if we wanted.  I had some extra volera foam left over from making a poker table a couple years back, so i decided to cut a triangle shape out of it to stuff into the bottom of the cape.  This kept the bottom spread out without adding too much weight.  To attach the cape to the shoulder pads, I simply hot glued some velcro onto the cape and shoulders pads.

The helmet was much more difficult to make with all of the odd angles involved and the fact that I was making it out of foam.  Because I didn’t have pieces that were big enough, I used 3M 77 spray to glue pieces together.  I started with the front of the helmet and used my scroll saw to cut the bevel on the outside and my electric carving knife to cut out the zig zags in the middle of the mask.  Don’t worry if your cuts are not exactly perfect…. you can smooth everything out later with your electric knife and sandpaper.  After I had all my pieces cut, I used the 3M 77 to glue all the pieces together for the main part of the helmet.

The red paint did not cover the dark foam very well at all, so I had to improvise.  I had some extra white paintable caulk laying around and decided to cover the entire helmet with caulk using a putty knife.  Just squirt on some caulk and spread it, working it into the little holes in the foam.  Below is a picture of the helmet that has been partially painted, but shows the caulk covering parts of the helmet.  After applying the caulk, the red paint definitely covered much better, but it did add a little more weight to the helmet.

One little problem…

The helmet is MUCH bigger than my son’s head.  In order to make this helmet actually wearable, I created a little foam ring that goes inside the helmet.  I also added some extra foam blocks for the foam ring to sit on.  After that, I just added some other foam pieces here and there to make the fit a little more snug.

I made the “wings” as a separate piece to be glued on later (after painting).  I glued together several pieces of foam to make them into thicker “blocks”, and used my scroll saw again to cut the bevel on the edges.

After making a few minor adjustments, I painted the wings with black FlexiDip.  This took several coats, but I didn’t have to worry about covering the foam with caulk because the paint covered pretty well.

To make the little pendant that goes in the middle of the wings, I just cut out several pieces of volera foam, hot glued them together and spray painted them yellow.  Then I hot glued the pendant onto the wings.

I made the little coffee cups (as my son calls them) that sit on top of the wings by cutting up some different sized round foam insulation that is used to insulate pipes.   Then I glued all the little pieces together and spray painted them before hot gluing them onto the wings.

I used hot glue to put all the helmet pieces together.  Here is how the helmet came out!

Finally…. it was time to put it all together! The only thing left to add was some grey clothes to wear under the costume.  What a fun project!  My son and I definitely had way too much fun with this.  He even told me that the whole family should make costumes for next year.
