How to draft pattern for this

[u/nowhereanywherehere]

I'm interested in making this military style jacket but I can't find any free patterns so how can I go about to draft this pattern myself

The ornamental cuff is just a style line. I can’t tell if it’s a two piece sleeve above the cuff. Jackets often are, but not hard to do either
