breeches again

I'm down to the mostly handsewing part of the breeches which is when I always slow down on a garment.  I know some of you can handsew like lightning but I am just a tortoise.  So the waistband is on, and I decided that the edges were not as crisp as I would like, so I am hand top-stitching them (just a running stitch) and that is looking much nicer.  One side is done, the other partway.

I found the amazingly nice metal buttons from a few years ago's scrapped 18th c suit, and they might work on this one, but I really want to use plain self-fabric-covered ones at the breeches waist and then just use nice ones on the legs and coat.  I'm trying to convince myself this is period.
