why was national dress needed to define the cultural identity?

(i) A nationalist feeling swept across India by the late 19th century. Indians began devising cultural symbols that would express the unity of the nation.
(ii) Artists looked for a national style of art. Poets wrote national songs. Then a debate began over the design of the national flag.
(iii) The search for a national dress was part of this move to define the cultural identity of the nation in symbolic ways.
