I really don't see why Sania needs to be apologetoc at all about what she wears and I definitely don't think that what one chooses to wear needs to be justified to anyone. Her dress is not a reflection of her morality. Adherence to religious and societal norms is a part of it but morality and character goes beyond just that. Those who are not able to look beyond her skirt have no right to comment on her religion. This is not just an issue of a dress code of sports. this is a larger issue about our chioces too.
