NOTE: The words modest and modesty are too often used in an incomplete manner. Modesty refers to a person's character, and not merely to a manner of dress. Clarification needs to take place in discussions about modest dress so we understand that there is more to modesty than making sure your skirt hits your knees. Charity, virtue, humility, constraint, and meekness are all characteristics that make a person "modest". That being said, this post will concentrate only on modest dress.
So you see: Dressing modestly ─ it's totally a plan of salvation thing.
