I think some distinctions SHOULD be made, and I can't comprehend why I never see anyone making them in these threads. I hope that will change, at least if or when the great restoration happens.
The most glaring problem with the posted dress code image is that it only says what is allowed on weekdays, but other than that it is largely a lot of negatives. It also does not make the distinction for weekdays of obligation, or Requiem Masses, or if going to church for things other than a Mass, or if a procession follows, or if it matters if the Tabernacle is placed elsewhere such as on the night of Maundy Thursday. Newcomers would have such questions, I would think! I love how the Code of Canon Law, and everything in the one true religion, has no absurd ambiguities like these. You don't have to be an intuitive extrovert to be saved, to receive graces, or to have a spiritual life!
Wearing a suit jacket, much more a cravat or tie, is inherently irrational. There is NOTHING wrong with the TRADITIONAL practice of a boy or young man (particularly those still growing) wearing short pants. Discouraging this imposes an unnecessary burden for those who might find difficulty in finding transportation which does not affect the lowest part of your body, notably when there is flooding at any level on the ground anywhere on the way to church. If you use a bicycle or other similar vehicle to get to church, the cruelty could be even more evident! It also creates a sense of undue prejudice if only girls and women can wear skirts. I challenge anyone to find me where the universal Church ever authoritatively forbade men from wearing kilts, robes, cassocks... oh, right! You can't! I am all for true inclusivity, not the liberal perversion, as I have said before... While that might not be you or your relatives, there is absolutely no Salvation outside the Church, so such rules should and must encompass everyone without exception.
Cross-dressing (firstly) and encouraging people to lust (secondly) are evil, but how evil is it for anyone to let their vanity discourage people (i.e. not dressed immodestly nor out of gender, yet not conforming to YOUR own secular standards) from converting to the true Church and attending the true Mass? Largely before the resurgence of the paganism, vanity, and effeminacy in the so-called Renaissance, the societal standard of clothes in the Western world generally made more sense. You can see this reflected in Catholic vestments as opposed to тαℓмυdic ones, and in Catholic paintings and sculptures. Obviously excluding those stripped by tormenters and such, would people dressed like them be welcome in church? The answer better be YES, or else I do not see how you would not be guilty of schism! Or will you point out "decorum" ...by whose standards... the infidels who run the world?!
I hope there are others who can concur with these points. If you disagree and want to thumb down my reply, I hope you can cite Catholic teaching as to how I erred, and go read chapter XII, verse 36 of the Holy Gospel of St. Matthew.
