The late 1940s was a time of somewhat boxy, padded blouses.  This blouse on the actress and dancer Suryakumari for example is almost like a man’s shirt (or perhaps more correctly a pyjama top).  As can be seen from the second pic, it is teamed with a bordered handloom sari. The translucent head covering seems an addition – these used to be common say around the 1890s and 1910s as the sari was evolving but perhaps not as late as the 1940s. The movie is 1948’s Samsara Nowka.
