I recently began construction on a civilian double breasted frock coat, and thought there might be some interest in seeing all of the work that goes into one. For myself, I'm estimating about 100 hours, but for a beginner, it could easily be 200 or more hours for such a coat.
If you have any questions, please ask away.
I drafted the pattern from Devere's 1866 guide according to my exact measurements.
Muslin fitting, front view. The lapels are just in place by hand to see what looks best. Need to let out the front a tiny bit, unfortunately.
I love the back view. The skirt, which I cut a little fuller than usual, drapes almost perfectly.
Notice how the armscye comes right up to the bottom of the arm. This was the practice back then, and is still used on higher end coats today.
