Necessity is the mother of invention.
"The idea initially came from (Lisa) Lindahl, an avid runner living in Burlington, Vermont, who found that conventional bras lacked the support or design that would make physical exertion comfortable. She wanted a bra with stable straps, breathable fabric, and compression. So she asked Smith, a childhood friend and costume designer, for help.This ain't no peep show, pervs. Safe for work.
Smith sewed two men’s athletic supporters together, which Lindahl tested while running. Later, the garment was modified with non-chafing seams and an elastic band for support. Lindahl partnered with Miller to co-found Jogbra Inc. in 1977, with the garment being patented in 1979. The sports bra market grew into a multi-billion dollar enterprise, and their invention is credited with helping millions of women take up running."
