As a niqabi myself i think it's none of anyone's business what I wear. i think government needs to poke their noses out of what women wear.

secondly, for the scholars and islamic group saying that the niqab is not obligatory in islam they have to realize not every muslims goes by that. there are islamic scholars who say its obligatory for women to wear. and i know some women who believe niqab is a must.

me personally i wear niqab because i want to get extra blessings from my lord. i don't think its a must but i think it's a very good thing to do.
