I heard an interesting argument today in a diocesan magazine. The author, a woman, commented that when she first heard of the objections certain Christians had to women wearing pants (back when women generally didn't wear pants), she was quite perplexed. That was my reaction too; I always considered that such people confused cultural mores with Gospel mandates. But she presented an interesting argument grounded in modesty for not wearing pants, specifically, that tight pants immodestly show the contours of the body that a dress (or, at least, a traditional dress) would not show. I never quite thought of it that way.
That doesn't mean that there aren't pants that are modest, or that there aren't dresses that are immodest (as everyone knows), but it puts a new perspective on the issue.
It may not be possible to go back. But it may be possible to keep modest in mind.
