Hey @
Brevin Din-Shay ! What @
Tan Djarka is talking about is the piece of material that wraps around Obi-Wan's inner robe and is directly underneath his belt.

It's the light khaki cloth band beneath the brown 'Star Wars Belt'. I don't know that you need to go that far with it. I like the simplicity of your outfit, I would however replace the dress belt with a homemade Tandy Leathers 'Star Wars Belt' or the like.
And as far as your lightsaber choice goes.... NAILED IT! Nothing beats a GRAFLEX!
