I know some of you think that certain dresses are not appropriate for mass. Recently some local churches in city where I live begin to make official rules about dress code for attending mass.
I think that such step is very unwise, because attending mass is more important than how to dress for the mass.
Supposedly I have used up all my “polite” clothes during work days, I haven’t got any chance to do my laundry yet, should I come to mass with my “inappropriate” clothes, or should I just stay home?
This is just one example where “Traditionalist mind” could override what’s important with what’s not.
It depends, are you worried about wearing jeans to Mass because everything else is dirty or are you worrying about wearing something that is actually an occasion of sin for others? Obviously, you should not wear jeans to Mass if you have other clothes, especially not to Sunday Mass. But if you honestly do not have anything better, it is no sin.
On the other hand, if you are wearing a tank top and short-shorts to Mass (as I’ve seen in NO parishes and not only on a single occasion or a single person!), then that is indeed sinful because you are creating an occasion of sin for others. It would also be sinful to wear that in public but because you are standing before the Almighty God in the Holy Sacrifice of the Mass, it becomes a much more serious sin.
So it really depends on what you mean by “appropriate” clothes. There are many clothes that you should not even have in your closet because they are always inappropriate (like short-shorts, miniskirts, tube tops/belly shirts, bikinis, graphic T-shirts with inappropriate messages, etc.). But if you are only worried that your Sunday best hasn’t been washed since last Sunday, either wear it without washing it (assuming it’s not too bad) or wear something else that is still modest.
As to whether it is better to go to Mass wearing inappropriate (immodest) clothes or to stay home, I would think of it this way. If you intentionally skip Mass, that is a mortal sin; but if you wear immodest clothes to Mass, that is also a grave sin (mortal or venial, depending on intention – mortal if your intention is to draw attention to yourself, venial if you honestly don’t realize that what you are wearing is drawing attention). So the easiest way is to think of it in extremes – would you walk into a church stark naked? Would you say, “Well, at least I am here, right?” If you would not do that, you should not go to Mass wearing immodest clothes. If you skip Mass, your sin is on your head; if you wear indecent clothes to Mass, you have your sin of immodesty
and the sins of anyone who commits a sin of lust by looking at you because you have created scandal. So, if you honestly do not own any clothes that are not indecent, that would be a moral obstacle to assisting at Mass and thus you would not have a Mass obligation. But you also need to find clothes that are not sinful to wear in public so you can interact in society.
So get some clothes which are not a sin to wear in public, clothes which are modest and appropriately cover the body (that is the purpose of clothing – to
conceal, not to
reveal), and especially some Sunday best clothes that you reserve for Mass, especially Sunday Mass.
