Blessings always follow obedience. Unfortunately, obedience often brings the disapproval of the majority, even the 'christian' ones. You must decide which is more important- following God's commandments, or following the whims of man.
My family began observing the 4th Commandment (Remember the sabbath day...) several years ago. We have been absolutely blessed by this, but VERY few in the so-called christian community will even listen to our testimony.
There are many other principles available to us from scripture, which put us at odds with the rest of society, which bring God's blessing. Consider it a test of your faith.
I've always followed that particular commandment (although I think of it as the third). The question is more on whether or not there is enough respect to dress appropriately at Mass or even Eucharistic Adoration. Some of us really take the time.
Another question is whether or not we see the "trappings" of feminine attire and presentation as being restrictive or freeing. That's more what this article is about.
