All of these subjects fall under the category of dress and grooming, a highly personal area. However, our dress and grooming speak volumes about us as individuals and as Christians. Though the ministry of the Church of the Great God does not "police" members in these areas, modest dress and grooming are expected of them.
Although God expects us to groom ourselves properly, setting a good example for others, the use of cosmetics may reveal a problem of vanity and pride (see Isaiah 3:16-23; I Peter 3:1-4). The use of earrings by men or tattoos and other ornaments of the counter-culture, may show rebelliousness. Much depends on a person's attitude. As we grow in the grace and knowledge of God—becoming more humble, modest and holy—our involvement with such questionable practices should diminish and disappear.
Notice Ezekiel 16:9-13. Christ decorated His own wife with ornamentation. Verses 14-15 show that as long as she displayed them to the credit of her Husband, they were wonderful, but as soon as she took personal pride in them and used them for selfish reasons, they became a curse to her. Isaiah 3:16-24 show these same decorations being taken away because of vanity and self-glory. Money, food, sex, alcohol, clothing or jewelry are not intrinsically wrong. Misused, abused or over-indulged, they are a stumbling block to a true Christian.
Beyond that, the Bible makes plain statements on hair length (I Corinthians 11:2-16) and tattoos (Leviticus 19:28). In principle, Peter covers both cosmetics and dress lengths in I Peter 3:1-4, stressing modesty. Men wearing earrings, traditionally female ornamentation, falls under the principle of cross-dressing, which God calls an "abomination" in Deuteronomy 22:5.
