Can Women Wear the Same Clothes after Menses?
Question

I had my period. Is it permissible for me, after the period ends, to put on the clothes that I was wearing during my period or must I purify them again?
Praise be to Allah.There is nothing wrong with a woman whose period has ended putting on the clothes that she was wearing whilst menstruating , so long as they are still clean and pure and none of the menstrual blood got on them. 
But if some of the menstrual blood got onto the clothes, then the place where it is must be washed before praying in them. 
A woman came to the Prophet (peace and blessings of Allah be upon him) and said: Menstrual blood may get onto the clothes of any one of us; what should she do with it? He said: “She should scratch it, then rub it with water, then wash it, then pray in it.” (Narrated by Al-Bukhari, 227 and Muslim, 291)
So the Messenger of Allah (peace and blessings of Allah be upon him) enjoined purifying the clothes before praying in them.
