You could Modify the Neo (Matrix) trench coat pattern that Simplicity carries in thier costume section. Basically cut back the lapels a touch and make a front panel with buttons, then modify the collar. Make a muslin mock first to make sure everything fits right cause vinyl can be mean to work with. (tissue paper between layers to prevent some stretching and paper clips instead of pins to hold layers together are some sugguestions.)
