A few things have come back without a noticeable change. I wore crew neck sweaters in college and my daughter’s generation wore them in high school 18 years later.
Doubt if we’ll ever see felt poodle skirts or circle skirts with a ton of crinolines under them. That would be considered “dressing up” to wear something like that now - something most people don’t do.
I also remember women not being permitted to wear slacks or shorts of any kind to work in the office and always wore heels, stockings, a girdle, a slip and a suit or dress. If that happened now, most women would not have anything to wear.
We couldn’t wear pants to school, until the early ‘seventies. That’s when dress really started breaking down.
It’s been a long time since I worked in an environment where it would really be appropriate to ‘dress up’; and I honestly don’t miss it much. I like being comfortable, and can’t believe that as a young person I wore stockings, garter belt, girdle, and all that stuff.
But I like to see people looking neat and stylish, it’s another art to admire; and especially if they’re representing me on a world stage.
That reminds me of when we girls wore hoop skirts under those full skirts. We made the huge mistake of wearing them to school. When we sat down the hoops and skirts went up over our heads.. We did not wear them again.
