I assume that you are a Christian who is concerned with imitating Jesus and being Christlike. Jesus never wore jeans, a t-shirt, and sneakers. He never wore a watch or a baseball cap. For formal occasions, he would never have worn a tophat and tuxedo. If you wear these things on informal and formal occasions, does that mean that you are not acting in a Christlike manner and that it would be appropriate to question your Christian commitment? I hope that you agree that such a question answers itself. Our Christian commitment is not demonstrated by wearing exactly the clothes that Jesus would have worn, but by imitating his example of holiness.
In the pope’s case, he wears a simple robe called a cassock and a simple cap called a zucchetto in ordinary life. For special occasions, such as when he celebrates Mass, he wears a formal robe called a chasuble and a formal headdress called a miter. These clothes signify his status as Christ’s Vicar and honor the occasions on which he wears them, much as our clothing signifies our state in life and honors the occasions on which we wear them. If it is okay for ordinary Christians to wear clothing for such reasons, it is okay for the pope to do so.
