The original push-up bra was created by designer Louise Poirier in 1964. In 1994, the Wonderbra Push-Up bra took the country by storm—the garment was sold at the rate of one every fifteen seconds. While there have been many imitators since then, the Wonderbra continues to be the top selling push-up due to its superior design and comfort.
