2021 Update: I hope to give this costume another whirl given some of the lessons I learned making this costume. In the meantime, if you are interested in making this costume keep scrolling! 
Finally finished my Halloween Costume!

2021 Update: Ok here is how I went about making this costume. I will try my best to break it down as to how you can make some, all or none of it yourself. Most of the details will be on how to make all of it yourself. 

Do It Yourself  

The Boots

Materials

• Pair of old boots or new boots 
• Fine or Chunky Silver Glitter
• Mod Podge 

What you will want to do is cover the boots with the Mod Podge and pour the glitter on the glue. You will do this until the entire boot is covered. Check out the video below for a quick tutorial on how to do this with a pair of shoes.  

The Shirt and Pants

Materials

• Silver and Black Rhinestone Trim (links redirect to Amazon so you can see what they look like, but you can buy them at another store) 
• Confetti Dot Sequin Fabric 
• Shirt and pant patterns like this one or this one
• E6000 Craft Glue

I used McCall’s pattern 7195 to make the pull over top

I can’t remember the pants pattern I used, they may have been self drafted, but I would recommend making a quick pair of pants from a pajama pants pattern like Simplicity 8518 or Simplicity S9020.

Even though I bought shiny confetti fabric, I did not use the correct side of the fabric – I thought it was a little too shiny. I used the wrong side of the fabric – essentially turned the fabric wrong side out and used that for my costume.

After you make the shirt and pants you will cut strips of black and white rhinestones and glue the rhinestones onto the shirt and pants. I cut the white rhinestones so I had four rhinestones in a row. I cut the black rhinestones so that I had three rhinestones in a row.

Before you put the rhinestones on the shirt and pants. Make sure to put a piece of cardboard inside the legs of the pants and inside the sleeves and body of the shirt. This will prevent some of the glue from seeping through the clothes.

You will see on my pants that there is about 7 inches of fabric at the bottom of my pants that don’t have rhinestones. You will also want to make sure that you do not put rhinestones on the part of your pants that will go inside your boot. If you don’t your going to crush the rhinestones when you put your boots on.

Please keep in mind that the glue makes the rhinestones stay on, but the end result is that you will have a fairly stiff shirt and pants. Once I try this costume again, I will post how I avoid making a stiff suit.

Feel free to leave comments with questions and I will do my best to answer them!
