The aim of this study is to analyze the physiological and sensory response based on brassiere types having two different design parameters, i.e., different length of wing and band width of the front panel. This study involved nine middle aged-women who participated in the wear test and data on their subjective pressure sensation, brain wave and skin temperature was collected using Neurodata Acquisition System Model 12 (Grass Co., USA) and MP100 Biopac System. The main physiological parameters that displayed significant differences based on the brassiere types included; slow alpha wave at O₂ and theta wave at O₁. When pressure was exerted around the breast area, there was an decrease in slow alpha while theta wave was increased at O₂ and O₁ respectively. The subjects were very sensitive to the difference in pressure between the experimental brassieres during the subjective evaluation. Lower chest tightness, overall tightness, and overall fit presented the most significant differences. The front panels’ long band enhanced the negative pressure sensation significantly at each level of the wing length. Consequently, it is suggested that the length of the wing should be longer when the band length at the front panel is wider, compared with the scenario where there is no extra band on the front panel.
