As one of my own personal projects I designed and made this trench coat myself.
I designed the coat to have a purple lining, welts and dogtooth buttons, which I also made myself using a laser cutter through plastic and CAD and CAM software.
These pictures show the final product.

A close up of the detail on the front including the welts. The buckle was slightly too wide which I was disappointed with.
The under side of the band also has the purple lining to be in keeping with the rest of the coat.
I even made the belt loops and band around the cuff myself.
