What Is An-In-One Facings
An all-in-one facing application is used to clean finish both armhole edge and the neckline simultaneously with a single facing compartment. This facing style is constructed similar to lining, but as opposed to lining, which covers the entire area of the garment's wrong side, an all-in-one facing stops at about 2-3" below the underarm edge. These convenient facings results in an even, structured application along all of the garment's upper edges.
The facing compartment is aligned and stitched similar to the upper portion of the garment. The facing as both shoulder seams and sides seams which naturally correspond to the garment seams in the finished application. Typically, an-all-in-one facing has curved bottom edges to ensure they go around the body's raised edge such as the bust area and shoulder blades. This ensures that the facing layer remains flat agains the upper body portion and does not cause bulk or hinder movement one the lower, more organic portion of the body.
The front facing edge should be curved such that it goes over any darts or tucks as this will ensure the facing lays flush against the garment layer and not visible on its face side. Darts are designed to shape and mold to organic areas of the body - having a flat facing layer taht backs will not only disrupt this smooth shaping, it will also cause bulk and unnecessary thickness taht is often visible from the garment's face side.
