Young Teen College Girl Without Brassiere

Construction and fit
A brassiere usually consists of a cup for each breast, a center panel (gore), a band running around the torso under the bust, and shoulder straps. Standard, well-fitting bras are constructed in the form of a "square frame", anchored by a chest band, with all dimensions fitted (i.e., adjusted) for each prototypical wearer, assuming they are standing with both arms at their sides. The design also assumes that both breasts are equally sized and positioned. Some bras are strapless. Prior to 1900, fabrics like linen, cotton broadcloth, and twill weaves that could be sewn using flat-felled or bias-tape seams were used to make early brassieres.
Bra components, including the cup top and bottom (if seamed), the central, side and back panels, and the straps are cut based on manufacturer's specifications. Many layers of fabrics are usually cut at once using a computer-controlled laser or a bandsaw shearing device. The pieces may be assembled by piece workers on site or at various locations using industrial grade sewing machines, or by automated machines. Coated metal hooks and eyes are attached are sewn in by machine and heat processed or ironed into the two back ends of the bra band and a label is attached. The completed bras are transported to another location for packaging, where they are sorted by style and folded (either mechanically or manually), and packaged or readied for shipment.
