I used this tutorial over at Dana Made It to make the vest
I used the tutorial over at Lilybug Designs as my inspiration for the chaps but I had to come up my own pattern. There is also this tutorial to make the chaps or there is this tutorial as well which will work well. I made a belt out of fabric and put it through the jeans belt loops and the chaps loops I made. The chaps were made out of faux leather. The vest was made out of a non-pilling fleece.
I also made mustache tattoos with my inkjet printer and silhouette machine. Add a cute pin on sheriffs badge and some handcuffs and you have a great birthday present.
