Initially in every religion initially people opt to wear particular type of dress ,different from other region people ,be in prescribed dress, be beard or be without beard,follow the rules of their religions strictly , being orthodox.But I think .these are acts of class or standard one students only for initiation.Afterwards once we understand the meaning of religions ,and our hearts/brains are colored in the color of divine and love then these are not at all required.As we have to promote ourselves go to higher classes where color code ,dress code ,code of conduct ,are not at all required ,where every body is one and the same without discrimination.Even then,
if you want to be retained in lower classes always,then be orthodox,dressed as per religion ,keep beard ,it is all your will and wish.But I have always seen great people have/had always keep themselves away of all these ties, barricades and reservation.However ,I like white dresses very much..
