The general issues are these:
- Between sports or leisure wear and more āprofessionalā wear, the professional wear is preferred for Sunday and Holy Day Masses. Sunday Mass is the high point of a Catholicās week, and it deserves to be prepared for in its own right and dressed for in its own right, rather than to be a āstopā between the events for which the Catholic chooses clothing appropriate to those venues. (In contrast, people normally wear the clothing proper to their work day to daily Mass. Although the high point of their work day, daily Mass is part of a work day, not the high point of a day set aside primarily for worship and resting in God.) It is often remarked-upon that less affluent people are actually the least likely to dress in a slovenly manner for Mass. By the plain reading of the New Testament, OTOH, between the choice of solemn but simple or solemn but obviously expensive, the more simple clothing is to be preferred generally.
- Unless one of your duties at your parish is to establish and communicate dress codes for certain peopleāsuch as the choir or the altar servers or the lectors, et ceteraāthen dress codes at church are for you to think about in your own closet. It is very rare that a Catholic needs to have an opinion about what other people wear to Mass. Even if it is your duty to communicate dress codes, it is best to confine yourself to the audience that it is your duty to address.
On that account, this kind of thread really ought to be a place for Catholics to sound out how others respond to the various clothing choices they might make. It is better if it
doesnāt become a place to complain about our brothers and sisters in the faith who see things differently or for reasons we cannot fully know seem to put little care into dressing for Mass, as tempting as that obviously is.
I would point out that I know a family in which the parents required a āno jeansā policy until their children reached age 18. The children report that they eagerly wore jeans to church for a few Sundays after it became their decision, but they all went back to wearing clothing that was nicer. They found that they liked being dressed especially for Mass, rather than dressing as if they were just out and about for a leisure activity. Those who have never tried making an effort to look their best for Mass ought to try it, then. They may find it changes the experience for them in a positive way.
