The idolatry of dress is a moral disease. It must not be taken over into the new life. In most cases, submission to the gospel requirements will demand a decided change in the dress.
(MYP 358.1)
There should be no carelessness in dress. For Christ’s sake, whose witnesses we are, we should seek to make the best of our appearance. In the tabernacle service, God specified every detail concerning the garments of those who ministered before Him. Thus we are taught that He has a preference in regard to the dress of those who serve Him. Very specific were the directions given in regard to Aaron’s robes, for his dress was symbolic. So the dress of Christ’s followers should be symbolic. In all things we are to be representatives of Him. Our appearance in every respect should be characterized by neatness, modesty, and purity. But the word of God gives no sanction to the making of changes in apparel merely for the sake of fashion,—that we may appear like the world. Christians are not to decorate the person with costly array or expensive ornaments.
(MYP 358.2)
The words of Scripture in regard to dress should be carefully considered. We need to understand that which the Lord of heaven appreciates in even the dressing of the body. All who are in earnest in seeking for the grace of Christ will heed the precious words of instruction inspired by God. Even the style of the apparel will express the truth of the gospel.—Testimonies for the Church 6:96.
