Point out what is dumb so I can think about it...will you?
That a Catholic would have any concern whatever for modern fashions.
The best way to judge the appropriateness of clothing is by custom; follow it without fail. Because the human spirit is prone to change and the things that pleased us yesterday no longer do so today, there have been invented, and are still being invented every day, all sorts of different ways of dressing to satisfy this changing spirit. Those who would want to dress as people did 30 years ago would make themselves look ridiculous and eccentric. It is, however, characteristic of the conduct of people of good judgment, never to attract attention to themselves in any way.
- St John Baptist de La Salle, page 49, The Rules of Christian Decorum and Civility
Within reason, of course!
The Saint did not mean what he said in an absolute sense, however. The problem with today's fashions is that it seems that almost all of them are corrupt. So, one must indeed make an effort not to be eccentric, drawing attention to oneself, but this insofar that adjusting to the custom does not become a sin.
Since the present apostate world considers loving God and living holy lives 'eccentric', the referring of the Saint to real eccentricity does, in most cases, not apply to the present state of things.
Now, since I do not live in America, I have no precise knowledge of what the general practice is among traditional Catholics there. So, I do not know whether there are many Catholics there who truly dress in an eccentric way. But I have not noticed much eccentricity (in the sense of looking truly weird) among traditional Catholics in my own country. If anything, it is my opinion that some here (in my country) seem to be, to a certain extent, too influenced by the world when it comes to dress.
Ironically, to me the modern fashions fit the definition of eccentricity quite well, in contrast with the customs of saner, more Catholic times. The world has become a circus, and absurdity has become exalted as the 'norm'.
When I hear someone say that long skirts are 'eccentric', I cannot help but think of the revolutionaries of the sixties who temerariously attempted to compel nuns to abandon their habits for secular clothing which was more revealing. Terrible.
