Here you can see (and you can click for larger images) the pad stitching which lends the revers its shape. I haven't ironed it, but it maintains a fairly sharp crease, and also curls back toward the point of the revers. Underneath you can see the dart that gives the chest some shape, and a few dimples where the pad stitching is.
Underneath the armscye I've added a little padding. This is batting covered by thin linen which I've pad stitched to the fabric. This will fill out the little hollow under the arm.
A final picture of the completed interior of the front of the coat.
Now I've attached the back and skirts, and added a strip of linen at the bottom hem to help keep the coat draping properly.
In addition to the linen strip, I've also added a few lead weights. This is a very soft linen coat fabric, and the weights will help it hang properly.
I've begun turning in the fronts in anticipation of adding the facings. You can see here an additional piece of linen added to help support the buttons along the front edge.
Now to add some pockets. There are no side or front pockets on this coat, to maintain the proper form, but instead it has two pockets hidden in the tails. I've cut the lining for the tails in two pieces, and made pocket shapes.
In retrospect, I should have cut the pockets to be shaped within the red dotted lines - this would have helped them hang straight, since they would have been supported by the waist seam.
The finished pocket. It may be hard to see, but I've added reinforcement at the corners of the pocket opening so it doesn't rip open.
A closer look at the pocket.
Completed skirt lining. On this side the pocket is at the top left of the lining, by the top of the back vent opening.
