After we finish perfecting the design in the prototype phase, we make a size set so that we can evaluate the fit of each size. Another reason we use the size set is to test the placement of labels and final trims. Size sets can also be used as a salesman sample because they are standard that we use for quality when running production on a style.
WHY is this step needed?
This step is the meat of the process. This where you see, test, feel and wear your product. The final prototypes are representative of EXACTLY what production will look like.
