This photo detail taken from the post I boosted earlier about the Don McCullin exhibition.
Photo taken in 1958 shows how little men's fashion has changed in 61 years. You could wear one of those suits now and it wouldn't look dated.
In fact you could probably go back another 50 years and suits look pretty much the same.
Hairstyles look unchanged, too.
Women's clothing is fashionable. Men's is more often practical.
Not sure men's suits are that practical. My daily "mountain wear" type clothing is much more practical. Suits were a civil interpretation of the military uniform, I believe. That remains unchanged.
Formal fashions, for men & women, haven't changed much in decades, though things go in cycles. Everyday wear has changed dramatically. For example: my grandfather would wear a three-piece suit every day, regardless what he was doing.
Ugh... sometimes I just can't English.
Women's clothing is fashionable. And often better represents the time's moral standings. Men's clothing tends to be less... plastic.
