I almost forgot about Anandi during that phase, even though someone posted a picture of Ganga afte divorce. Now it seems most probable that creatives think rural look is not complete without mang tika - so Anandi and Ganga persisted with this ornament. But Anandi knows this - plus the little girl with pallu on head (plus she is illiterate in this age - improbable for a girl if she is living with her parents unless they are too poor and the girl does not look poor at all) - so she should have immediately deduced that the little girl is married.
@ Bold Yesterday I was watching old BV episodes (before AnSh marriage) and girls from Anandi school were not wearing pallu on head including Gulli. Of course they didn't put on any mang tika.
Ashima wore Anandi's lehenga choli when she came to BH and Sanchi tried to impress KB & BH elders showing fake love for traditional costumes but they never put pallu or mang tika on head.
Found this in picture gallery.
I observed Bhago, Harki, Nimboli and few other women always wear the same borla. But people who belong to rich families use different styles of mang tika like Sumithra, Gehna, Anandi (as BH bahu), Ganga etc...and Suguna, Anandi (after her marriage with Shiv)...
