With 90+ posts, I really can’t say something that has already been said, but I will add this.
The hemline competition is just that. Very competitive. If I were a woman of semi decent looks, and pitted against 100s of other women in my age / demographic area, I’d look for every advantage I could find to put me in the top 10%. A hemline that pushes the outer limit of tznius would be just such an edge.
Can’t blame the women who do push the hemline to the limit, but kol ha’kovod to the women who don’t. At a recent family gathering, it was quite a shocker to see how a few of the younger girls were dressed. So what alternative does that leave for the folks in their 30s and 40s?
Either retreat and admit defeat or fight back. Either way, its a tough call to make.
Glad I’m not in this battle.
