"The distinguishing signs" in the Jews' clothes related to their form, colour or additional details have existed in all the countries where the Jews lived. In Middle Asia the the "distinguishing signs" of people of different religion were to be a head-dress, an overcoat and a belt, this clothing distinguishing the Jews from the Moslem population. After a detailed study of these kinds of the Bukhara Jews' clothes the author has drawn a conclusion that the sources and stability of the "distinguishing signs" in these clothes should be sought in the Jews' historical and cultural own experience of interaction with the surrounding peoples. On one hand, the clothes performed differentiating functions typical of all the peoples of a region, and therefore neither the Jews, nor the Moslems thought therm to be humiliating. On the other hand, "the distinguishing signs" were one of the ways of distancing by the Bukhara Jews themselves from the other religions communities and corresponded to the norms of Jewish tradition.
