Young Teen College Girl Without Brassiere

A brassiere (UK: /ˈbræzɪər/, US: /brəˈzɪər/; commonly referred to as a bra /ˈbrɑː/) is an undergarment that covers, supports, and elevates the breasts. Since the late 19th century, it has replaced the corset as the most widely accepted method for supporting breasts. A wide variety of bras are manufactured today.
Depending on her desire to conform to or rebel against cultural norms, a woman can choose from a wide assortment of bras for a variety of purposes: to enhance the perceived shape of her breasts, to minimize or to enlarge the perceived breast size, to restrain breast movement during an activity such as exercise, to enhance her cleavage, to conceal her nipples, to overcome sagging, for prosthetic purposes, or to facilitate nursing. In certain circumstances, like the work place, employers may require a woman to wear a bra. In most Western countries, the majority of women wear bras, although a minority choose to go without, sometimes for health or comfort reasons. Breast support is built into some garments like camisoles, tank-tops and backless dresses, alleviating the need to wear a separate bra.
Most bras are designed to be form-fitting and to lift the breasts off the chest wall if they sag and to restrain their movement. Bra designers and manufacturers originally produced bras that were purely functional and gradually added elements to improve the design, but they have now largely shifted from functionality to fashion. Manufacturers' standards and sizes vary widely, making it difficult for women to find a bra that fits. Bra-measurement procedures conflict with one another. Even professional bra fitters disagree on the correct size for the same woman. Women's breasts vary widely in size and shape; most are asymmetric to a degree and can change from month to month depending on the menstrual cycle, pregnancy, or weight gain or loss. As a result, from 75-85% of women wear the incorrect bra size.
