Denim used to be a signifier of rebelliousness, and that may partly explain why I’ve been wearing blue jeans for the last 50 years. Not the same pair I hasten to add, but successive variations on a theme. Small but important shifts in length, leg-style and waistband have reflected the various whims of the fashion industry, but really they’re more or less the same thing. Perhaps no longer so edgy - in fact they’ve somehow accrued a sort of staid, conservative image, unsurprising perhaps, given how little they’ve changed compared to everything around them and in them. The other day, though, it occurred to me that the pockets seem to be getting shallower. Either that or my hands are growing, which seems extremely unlikely. And that reminded me of how pockets used to be stuffed with loose change, a rarity these days when all you need is plastic. Nearly everything I buy goes on a card. And apparently there are places now that will only accept card payment. Phone, watch and contactless transactions are on the rise - your pockets may be empty, but you can still pay. It’s part of the sublimation of everyday interaction, the cashless society. But pockets are here to stay. I mean where else would you put your hands when slouching against the wall? And where are going to keep that all important rectangle of plastic?
