Many apologies for concentrating on male fashion, but I think female fashion gets quite a bit of press already.
Fashion changes to suit the environment and circumstances.
In the way back then past pockets were separate bags attached to the belt. Then they started to be attached more permanently to clothing. As technology changed special pockets were created. Sometimes they disappeared after their reason for existence disappeared. Like special train ticket pockets in jackets. Other times they carry on through habit, though no one knows why they exist. Like the little watch pockets in jeans.
Another more recent example would be that of morning coats and their long tails. Originally the tails existed to make it easier for the wearer to ride a horse. The two tails falling either side of the horse’s back. When the high tech automobiles came along, coat tails were a distinct hindrance and so went out of every day fashion. They stayed around for formal wear and special occasions because of the association with horse riding which was seen as an upper class thing.
Coming to the present day and the introduction of new technology such as tablets and phone, it’ll be interesting to see how fashion handles them. Tim Worstall wonders if waistcoats might come back into fashion because of their pockets which could hold a small tablet/large phone.
Will we see a resurgence of fancy waistcoats just as colourful and stylish as women’s cloths are? I mean, why should men have to make do with the same old suit and tie with only the tie being used for a bit of colour.
But could an alternative come into fashion instead? What about man-bags? Men’s trouser pockets are already bulging with having to carry a wallet, phone, keys, spare glasses, and penknife. A waistcoat wouldn’t be able to hold all of those items. Not unless you go down the style of an angler’s waistcoat. But man-bags would be able to hold all the normal items, plus a business man’s accoutrements.
Or will it all be ignored as foldable phablets are invented which fit into the trouser pocket.
