The aim is to study the factors taken into account in determining the cost of a camisole in the commune of Kanshi, town of Mbujimayi and province of Kasaï-Oriental, in the Democratic Republic of Congo. The aim of the study was to ascertain whether the factors used were subjective or objective. After analysis, the investigations showed that the factors are more subjective than objective, because for the same model of camisole, the costs are different.
