With attention to the dynamic functional property of commercially produced brassieres, this study was conducted to clarify the relationship between clothing pressure and breast vibration. The clothing pressure was measured at rest and during exercise in 11 adult females aged 21 to 26 years. Movements of the breast were visualized by stripping of the brassiere cup without deflecting its functions. The clothing pressure on the breast at rest was obviously higher under the lower half of the brassiere cup than under the upper half of the brassiere cup because of the gravitational force. They were also influenced by respiratory movement of the chest. The analysis of the relationship between clothing pressure and breast vibration during exercise revealed that the clothing pressure of the lower half of the brassiere cup increased during downward movements of the breast and decreased during upward movements of the breast.
