WHY WOMAN NEED TO PROVE??

I was wondering from few days why female need to show her married status by changing her clothing and also putting bindi,sindoor etc…

Is it not enough that girl already comprised her identity by changing her last name ,lifestyle even she  left her home and moved to new house to make it home.I was travelling couple of days ago and saw all these taboos are limited to women who are not much famous or could not take her own decisions .Life is not easy and everyone knows it but why woman have to understand every situation and end up compromising????

If you ever give it thought  woman who is Doctor,Lawyer ,Judge or any dignified position  will never carry any taboos like bright cloths,bindis and even some don’t wear sindoor..So Does that mean they all are rebel? they cannot manage personal life but the truth is these taboos will never show how well woman mange her family and how happy the family is…

If man doesnot need to show the proof of being married WHY WOMAN???
