When did Chudamani, Sindoor, Mangalsutra became mandatory for married women, no one wear it in epics

In both of the epics, Ramayana and Mahabharata, these aren't the signs of being a married women, Chudamani is specific to Sita because that's her personal and recognisable head ornament which she gave to Hanuman but no such mention of Draupadi or any other women wearing Chudamani. Sindoor and Mangalsutra are just not present at all. When did they become mainstream in Hinduism for married women?
