Well, the old dress expectations were gotten rid of because some girls found it uncomfortable or inconvenient. After all, if you weren't expected to wear a modest skirt and sensible shoes, you could wear casual jeans and sneakers. Big win for freedom, right?
However...
You see so many young women today walking around in dresses that cover nothing and heels that don't stop. It hardly seems to be a victory for comfort, ease, or self-respect. I believe people should be free to wear what they want, but I also believe there's nothing wrong with people saying "nice women don't dress that way." Is women's happiness really helped by the elimination of all standards of dress?
If the girls were just wearing a plain old jeans and a t-shirt I’d say “yes”. Nothing wrong with that. Modesty and comfort can go hand and hand. I don’t understand young girls dressing like pole dancers. That is beyond me.
