The safety and comfort play more and more important roles in foundation wear design. In this paper, the change of skin blood flow under pressure is focused on. Three healthy young females were recruited to participate in the experiment. The subjects were required to wear girdles of different design, and the pressures and skin blood flow at five feature points were measured by using AMI system. Moreover, pressures of different magnitudes were exerted at the convex points of pelvis and hip by using the AMI pressure chamber, the change of skin blood flow under these pressures were observed. Some conclusions were drawn as follows: the pressure distribution under girdle was not uniform on skin surface; SBF increased under pressures, but it turned to decrease if pressure was very high; the skin pressure could be eased to varing degrees by the soft tissue, and SBF was influenced by the pressure exerted on capillaries rather than skin pressure.
