Step 1
Trace a copy of basic block with darts and negative ease for stretch fabrics. The ease is reduced in % according to the amount the fabric stretches.
Draw the underbust line and widen waist dart as a rocket: the underbust to waist section is 3cm wide all the way, while the bust to underbust section is shaped as a classic dart.
You also need a copy of the basic sleeve – remember that sleeves on knits do not need ease at cap.
