Someone wrote to me asking to post this; she was having trouble attaching the image.

I would still call that immodest, as tight as those tops are.
Seems to me, you have to go back to the 1400 or 1500s to find "fashion" which was modest.

Which is why we try to stick with the "fashion" of Our Lady:  loose, not revealing, does not call attention to oneself, and feminine.

There has been for some reason a sudden arrival of Novus Ordo Latina women to our chapel.  Latina women are the most affected group by this dress-provocatively-to-attract-men mindset [....]

Your sentence was very confusing as you posted it: It appeared to contain an editing error that wasn't detected before posting, e.g., having some necessary words deleted by mistake.  You can't expect readers to understand your use of an entire clause as a compound adjective (must you even try?) when you fail to insert the hyphens (e.g., as in green above) that grammatically change that clause into a compound adjective that's correctly parsable.  Much better yet, how about "Latina women are the group most affected by this mind-set of dressing provocatively to attract men"?

Here is an example of the typical clothes they wear to mass, everything is always skin tight, like sausage casing.

Ugh!  Young Latina women, of whom there is no shortage in Central Florida, seem to consider obesity a characteristic to be flaunted instead of disguised, unlike women of nonLatina cultures in the U.S.A.   I'm fascinated that your, um, model displays what might be called platform buttocks: a characteristic that I've been told is typically negroid.  Altho' from the colonization history of the New World, we should not be surprised that such genes would manifest in various Latinas.  Pregnancy and recovery from the weight-gain once routinely recommended by physicians during pregnancies seems not to explain the majority of the obese young Latinas.  Perhaps if the young Latinas I am routinely sighting from day-to-day were of their "educated" class, e.g., college coeds or degree-bearing professionals, their attitudes and my overall impressions might be different?

We in Central Florida are enduring the arrival of on the order of 100,000 Puerto Ricans over the past 6 months (numbers waved around range loosely from 1/2 to 3 times that round number), blamed on the devastation caused by Hurricane Maria, but to keep this on topic, I expect their clothing styles to be more of the same.  Perhaps you're getting some of our overflow?

Maybe your photo would be worthwhile in a CathInfo topic from 2 months ago in a different subforum:
•  <https://www.cathinfo.com/health-and-nutrition/40-percent-of-u-s-adults-are-obese/>?
From my perspective here, the "40%" is rolling-on-the-floor-laughably low as an estimate.

[....] and despite bouncing from one man to another all their lives, they continue with the same error, teaching it to their daughters.

So with all that "bouncing" from man to man, when do those Latinas find time to settle into a validCatholic marriage during which they produce "their daughters"?   Shouldn't spinsterhood act as a genealogical dead-end for Latinas who teach "the same error" [†] that left them as spinsters?

-------
Note †: You are wearing blinders that prevent you from considering another habit that I've been told Latina mothers teach to daughters; it could be a severe error in treatment of any man who has self-respect, thus killing a romantic relationship that might otherwise lead to a Catholic marriage.  But it doesn't fit your agenda, and I concede that it would be off-topic.

Oh how did my husband put it.... I think he said something like this, "I'm not going to be that dad that tells their daughter to change into something more modest because immodest clothing shall never enter this household!"  

He seems to be forgetting that those girls will continue to grow and grow. That piece of clothing was modest yesterday, not so much today. : )
But, yes, I agree with him in principle.

The OP is no small irony in so much as it displays 2 impure fashion images and then complains about impure fashions.  As a man I can honestly say that were I to be pulled into staring at those images I would in all likelihood commit a sin if not necessarily by direct thought and even possible subsequent action then at the very least by having willfully and knowingly placed myself in the immediate occasion of sin.

Unfortunately, there are some Catholic websites such as traditioninaction.org that seem to think it is perfectly all right to place very impure images on their sites.  (It is particularly ironic for tradtioninaction.org to do so in so far as they carry a number of excellent articles rightly decrying the use of immodest/impure fashions.)

As Catholics we should never forget the basic Catholic principle that one may never do evil in order to bring about good.  That includes the placement of impure images on the Internet -- especially on a Catholic site!  

When I posted this there were 2 immodest fashion images in the OP.   Now there is only one which is by far the less immodest of the two.  Thanks to whoever had the second more immodest one removed!

Many years ago, we had one priest from the SSPX that would fly in for Sunday mass. He was like 32, and a real man.

I have not known another young SSPX priest that was as a man like that priest. The new seminary seems to be putting out in-natural inhuman robots with no manly temptations.

Just because they finished their lives as saints doesn’t mean they were so before they entered the convent.  Objectively, their dresses were a little tight.  Were they mortally sinful?  No.  But it’s wrong to point to that fashion as 100% acceptable.    

There’s a reason why nuns wear the habits they do - there’s 0% chance of immodesty - just like Our Lady dressed.  Many women don’t want to hear that, but it’s true.

I wonder if this is acceptable to the dress police.
