The invention discloses a human body model system for optimized design of a bra, which comprises: a support; the power driving device is arranged on the bracket; the power driving device is in transmission connection with the lifting device; the human body model is connected with the driving end of the lifting device, the lifting device can drive the human body model to move up and down, the human body model is a soft human body model and comprises a main body and a simulation skin layer, a simulation mammary gland is filled at the breast of the main body, and the surface of the main body is coated by the simulation skin layer. The manikin system for the optimized design of the bra disclosed by the invention supplies power to the lifting device through the power driving device, so that the lifting device drives the manikin to move up and down, the motion of a human is simulated, and the problem of inaccurate data caused by different testees is avoided. In addition, the human body model is a soft human body model, the breast of the main body is filled with a simulation mammary gland, and the surface of the main body is coated by the skin-imitated layer, so that the accuracy of the test is further improved.
