The pattern draft for the front part of the dress is over. Now we will draft the pattern for the back.
Mark M 0.5 inch from L. Mark N 1 inch from I. Join G-M-N-I to shape the back armhole. Other measurements are same including the dart. Draw the empire line as you did for the front side.
Cut through the empire line to get the back bodice and skirt pieces.
The only change to the back bodice is to mark the new dart base point X and extend the dart legs to increase the dart intake to 0.50 inch (this will be 0.75 for persons above 14 years) as you did for the front.
Unfold the back bodice draft and cut through the center back to separate right and left back pieces. Draw the seam allowances. It is 0.5 inch on all the sides except for the neckline and for joining the button and buttonhole closures, for which a 0.25 inch seam allowance is required. Extend the dart legs as shown in the figure.
I joined the button and buttonhole closures separately. They are drafted as follows:
A to B = C to D = Center back length + 1.5 inch (1 inch for fold at the neckline and 0.5 inch for seam at the waistline.)
A to C = B to D = 2.5 inches
The right one is for buttonhole closure.
E to F = G to H = Center back length + 1.5 inch (1 inch for fold at the neckline and 0.5 inch for seam at the waistline.)
E to G = F to H = 1.5 inches
Add seam allowances---0.5 inch for waist and sides and 1.25 inch for hemline fold.
Tomorrow I will show you how to draft the sleeves.
