To date, the characterization of bra support and contact pressure mainly relies on human wearer trials where reproducible testing is difficult to achieve and experienced technicians are always required. Through a scientific analysis of the bio-mechanical interface between the human body and the bra, a novel soft manikin system is developed for the evaluation of bras ‒ taking into account the level of breast support, displacement and wearing comfort during dynamic body movements and physical activities. Through this innovation, the most beneficial bra design features for different end-uses can be objectively identified.
