The original design plan was to make "hinges" of leather to serve as button plackets across the front, but once it passed midnight, I just wanted to get it wearable so I could go to bed. (Work in the morning at 6!) I made a fingerweave braid of brown and white and stitched it along the front seam, leaving loops to act as buttonholes. It made a nice finish, and is easily removable when I have time to re-visit the doublet and finish it the way I originally planned.
And yeah, I know what you're thinking. I did forget the epaulets. But I can add them later too.
