This is why it's interesting, and difficult, to write about "Islam" as it can have a large number of meaning to various people.
Nuns wear strict head covering most would consider "Christian". I think most people would consider burka's "Islamic". Not all Christians wear, or think anyone should wear, habits. To say, habits are not in the Bible, therefor they are not Christian, seems like a narrowly defined, ax to grind, argument. Likewise, to say the Burka is not an example of something "Islamic" would be disingenuous. Yet, you'll find a great number of apologists doing just that. Hence these threads go nowhere.
