When we become a Christian, we put off the old self, and put on the new self, which means we are clothed with Christ. Part of this means to put of pride in all its forms, and to put on humility and meekness, which is precious to God. This humility should be expressed even in the way we dress, which is what is called modesty. If modesty is humility expressed in dress, then we should examine the motivation for our appearance and dress.
