It is difficult, isn't it, to say whether we are turning into grumpy old women saying, in effect, "Well, in my youth no respectable woman would have dressed like that!" or whether we just have to accept that times have changed.
I have never found it suitable to wear a low cut blouse while working in an office, or teaching. And I find it reprehensible if teachers allow themselves liberties that the school rules forbids their pupils.
Obviously, during my stage career I wore low cut dresses, jeans that framed my back-side nicely etc. but that doesn't mean I find it appropriate for a female newscaster to be showing off her bosom - even although it is nicer than mine ever was!
Coming home in the bus the other day, I was facing a young man of twenty or so. He wasn't dressed to provoke, but his elasticated jeans fitted so snugly that I could see, to use the tailor's phrase, which side he dressed to!
Information I didn't really feel I needed, I may say. I mean I had no intention of sewing him a pair of trousers!
