Young Teen College Girl Without Brassiere

Commenting about brassiere design, British Chiropractic Association representative Tim Hutchful said, "Bras are like suspension bridges. You need a well-engineered bra so your shoulders don't end up doing all the work. Bras that don't fit will affect the shoulders and chest, and will almost certainly cause back pain as you get older."
Types of bras
There is a wide range of brassiere styles available, designed to match different body types, situations, and outer garments. The degree of shaping and coverage of the breasts varies between styles, as do functionality, fashion, fabric, and color. Common types include backless, balconette, convertible, cupless, custom-fit, demi cup, front-fastening, full coverage, halter, longline, minimizing, padded, plunge, posture, push-up, racerback, sports/athletic, sheer, strapless, strapless-backless, support, t-shirt, underwire, wireless, sports bra, and invisible. Many designs combine one or more these styles. Breast support is built into some garments like camisoles, single-piece swimsuits, and tank tops, eliminating the need to wear a separate bra.
