I post on the same message board as Sailor Kenshin. Sailor is a recent convert to Catholicism, BTW, as well as an enthusiastic and prayerful person.
The discussion on that other board has wound down now, but it got pretty heated. Here are some items I posted there on the subject:
From the Catechism
1387 … Bodily demeanor (gestures, clothing) ought to convey the respect, solemnity, and joy of this moment when Christ becomes our guest.
2522 Modesty protects the mystery of persons and their love. …Modesty is decency. It inspires one’s choice of clothing.
2523 …Modesty inspires a way of life which makes it possible to resist the allurements of fashion and the pressures of prevailing ideologies.
The Christian priority should not be the external decoration of the body with costly clothes, but the internal beautification of the soul with the love of Christ. The focus, of course, should be Christ…

So how does God want today’s teen girls to dress? Through the apostle Paul He said, “I also want women to dress modestly, with decency and propriety” (1 Timothy 2:9). That means He wants you to be careful with your appearance.

Do I think anyone should ever be turned away because he might come dressed like the cowboy? No, absolutely not. I think we should go back to an earlier standard. Wear your best. A farmer might wear his newest, freshly washed overalls. A businessman would wear his suit. A woman would wear her nicest dress. The cowboy would come and our deacons would get him some clothes. The minister would dress as one who knows himself to have a special calling to lead people into the presence of the majestic and holy God whom we must worship, as the writer of Hebrews tells us, “with reverence and awe” and to be the mouthpiece of God. This seems obvious to me, though I know it never occurs to some.

I think there are a few arguments that need to be addressed. Some would say, “It’s church. You should be glad that people are at least coming.” I say, “Yes—it is church. And I’m glad that every one who shows up, does. However, if you know you’re going to church, why not dress up just a little bit?”
Some might say, “But what if they’re poor. Maybe that’s all they have to wear.” I would say, “Well fine—if that’s truly all you have to wear, who am I to say? But, if church is a regular part of your day or week, then when you purchase new clothes, why not budget for a church outfit or two?” It’s easy enough to find a pair of cordury or khaki pants that can be worn for church as well as every day.
