The writer MK Binodini Devi (also Manipur royalty) with her sister MK Tombasina, both in the striped phanek. Puff sleeve blouses for young women are fairly common at the time (possibly late 1930s/early 1940s).
Her mother’s attire in 1922 while also a sarong+blouse looks a little different.
Another example of the attire on the Maharani of Tripura.
