I found this here.

I shopped the second hand stores and found some boots that looked like they would work and a belt. I had recently made a bunch of costumes using a very simple tunic design that I could easily do without a pattern, but I used a costume pattern's hood for a princess (I believe) to make the hood. The top was simply a long rectangular piece of material that I pleated to look like Obi-Wan's top. I also made a white sash on which I glued a section of the belt I had found at the second hand store. I only glued the belt on in 3 spots, so it is easy to clip on the light saber, that I also bought at the second-hand store.
Here is the finished product on my grandson.
So you noticed that the pants don't match the outfit. I decided to not make pants. I knew that he would be wearing it over his clothes and didn't want to make the outfit too hot and too cumbersome to put on.
He loved it!
