So I made shawl collar morning coat.
Cutting. Needs seam allowance 0.5 - 1 centimeter. The gray line of facing does not need seam allowance.
Sew up the middle of the back (b - g). Sew the front and the back at the shoulder (a - c).
Sew the sleeve to the body (d - c - d).
Sew up the underarm (e - d - m).
Sew up the middle of the under collar (b - i).
Sew the facing to the body (f - e - i' - e - f').
Notch deeply the seam allowance of the collar (a and a').
Turn inside out.
Sew the collar and under collar to the body (a - b - a).
At this time, you may sew the back facing together. I didn't do so.
I sewed the back facing to the body with ladder stitches (h - a' - b' - a' - h).
Slip-stitch the hem (j - k), the vent (g to bottom), and cuffs.
Fold the collar. Make a buttonhole. Sew a button.
