I went to Mass this morning at the independent church I go to, and there was a young lady wearing a short(er) skirt. It was pretty short, especially in the back, to the point it was above her knees in the back. I saw her walk in, and I went up to her after I got my children settled in the pew, taking my infant back, and I advised her that there were longer skirts in the basement that she could have, and that I would turn the light on for her down there.
She didn't change, and after Mass, she kinda gave me a look (I thought). I thought to myself, "Well, it's better if someone says something privately to her, than to have people gawking at her committing a sin, and/or people talking behind her back."
I wasn't trying to offend her. I was concerned that her skirt was immodest and that it offended Our Lord, and I was concerned for the people that she ended up sitting in front of.
I don't think I was out of line at all, and I believe I'm going to bring up the topic to the priest(s) at the Church, because I'm seeing more youngsters (teenagers and even 20's) coming into Mass with skirts just barely at, and even a few inches -above- the knee, which really do not meet the standards of modesty.
It's something we should all be concerned about, and carefully tend to as far as with our children, and charitably mention it to those that we come in contact with, -especially- at Holy Mass.
