Peculiarities and characteristic raw materials of the nursing bras available in the retail market were established. The requirements to be put forward for a nursing bra and its fabrics were established. The aim of the research – to qualimetrically estimate the industrial prototype project of the nursing bra with moulded openable cups. By applying the objective measurement, experimental wearing and expert evaluation methods, the arithmetically weighted qualitative summary index of the nursing bra prototype was established. The physical-mechanical properties of the cup fabric (art. M/17952/066) and the base fabric (art. 539S) of nursing bra were tested in laboratory conditions to establish the permeability of air (LVS EN ISO 9237:2001), stretch properties (BS 4294:1968), and thermal and water-vapour resistance (LVS EN ISO 11092:2014). In addition, the physiological comfort of a woman in the just-designed nursing bra pursuant was forecasted.
