3 Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel; 4 But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in sight of God of great price.
This verse tells us, it is not what is on the outside. We are suppose to be about furthering the Gospel. We are not to concerned with the outward appearance. Our job, while we are here on the earth, is to serve God. We are to follow as He leads and point others to Him along the way.
Now do not misunderstand me this is not a free pass to wear whatever we want, because it is difficult to lead someone to The Lord when they are to distracted by your body. We still have a responsibility to dress as a woman, and to dress modestly.
The problem is when we over-emphasis things, like wearing skirts, that we become legalistic. I know too many people who have been either standoffish or completely turned off because of how they were treated by legalistic people (some where not "skirts only").
My point is I know that I have been getting too caught up in legalism. I thought once you were saved you should "look" a certain way, so that everyone you came across would look at you and say there is something different about her. I have come to realize that modesty does matter, but what matters even more is winning someone to Christ. Yes, as a daughter of the King of Kings, you should dress and carry yourself as one, but let's stop getting caught up in the legalism of it.
