Brace yourselves for the answer, because, if you're Christian or Jewish, your religion commands the same thing!
Yes, I know I look like a ninja - especially because I like to wear black... a lot...
But, if you're of any Abrahamic religion - Islam, Christianity or Judaism....
You are supposed to wear hijab, too!
And, this is not my personal opinion...although I would greatly prefer not to see your boobs, and your bellybutton, and your butt cheeks... at least not all in one outfit. The Bible and Torah mention hijab as well!
