It's made of fleece and lined in cotton (only the bodice).
The pattern is my own design and though you can't really see it, the lapels are embroidered (in black, because clearly, that's whta this coat needed. More black!).
The buttons are silver and are part of my super special Cheddar Gorge stash (acquired for me by a very kind friend), because I wanted it have one bit of the coat that wasn't black!
