In all the most widely used systems

In all the most widely used systems or methods of drafting garment patterns, the so-called structure of the draft is described as being "laid in the square." By this is meant that certain vertical and lateral lines are drawn, thus forming a kind of framework for the various fitting points and style lines which have to be superimposed. The fitting points are those which denote parts connected with the actual fitting together, or joining, of the pattern sections; the style lines are those which indicate the general design of the garment for the cutting of which the drafted pattern is to be used.
