It is either what the Lord requires of you, or it is not.
Now, if it is as many believe, commanded in the Scriptures for women to cover, then any women who do not are in sin.
I don't think it's either or. And you will discern as you read, that it is not either or with those who write on this subject.
Some even go to the extreme and believe that the women who do not cover, or who even trim their hair, are hell-bound. I have personally spoken to some of those who believe this so I am not exaggerating.
"He has told you what is good and what it is the LORD requires of you: to do justly, to love mercy, and to walk humbly with your God." Micah 6:8
