@beamgoes99.am Only exposed seam allowances need to be overlocked to prevent fraying. The coat has a lining so everything is covered. In traditional tailoring only leg seams of trousers need to be overlocked.

Hi there the 3/8" seam allowance has been already included in the draft (in forepart and sidepart). Check points 17 and 17A in the draft. Alterations will be done at the side seam if necessary so no inlay needed here.
