Fitted and semi fitted bodice

First step is to trace your basic bodice block,  

 like the picture bellow. left one is the back of the bodice, and the right is the front part of the bodice.

 

 

Second, for the fitted bodice I use the red line and for the semi fitted I use the blue marker line.

Fitted Bodice :
1. raise the arm hole about 0,5 cm up from the arm hole line and about 1 cm in.
2. measure 0,5 on the side seam on the waist and hem part. then true the pattern.(use curve ruler)

Semi Fitted Bodice (blue line) :
1. Extend the side of the bodice by 0,5 and blend the shape using the curve ruler.
2. Drop the armhole by 1 cm and then true the new arm hole using a french curve ruler.
