I WOULD like to know how Tesco is reacting to the latest fashion trend.

It wasn’t that long ago that certain branches of the supermarket chain banned people from wearing pyjamas while doing their shopping.

People were sporting nightwear and slippers to pick up their groceries, and notices were put up in stores prohibiting the practice in case it offended other customers.

But now, anyone can shop quite legitimately wearing pjs. Pyjama suits have become the thing to be seen in. This year the bedroom look hit the catwalks at major fashion shows and they have been further endorsed by celebrities such as Rihanna, Kate Moss and Rita Ora.

Pyjama-style trousers are selling like hot cakes, with M&S selling 10,000 pairs in three weeks.

I’m all for casual dressing - I don’t own any posh clothes - but this is taking things a bit too far. Now you can literally jump out of bed, wash and go. Head off down the high street in jim-jams, slippers, the works.

It’s just too sloppy for my liking, another indication of how slack and couldn’t-care-less society has become. Now mothers who turn up at the school gates wearing their pyjamas - and there are plenty of them despite it only taking a couple of seconds to pull on a pair of trousers - can do so quite legitimately.

I’m not condemning the odd lapse. A few weeks ago I got up early to drop my daughter off at work and threw an anorak on top of my pyjamas. I wasn’t intending to get out of the car but stopped at the post office on my way home. It was only when I was in the queue and glanced up at the CCTV that I registered, with horror, what I was wearing. It was a genuine oversight and I don’t make a habit of it.

Wearing pyjamas as clothes is an extreme form of dressing down. The way we are going, the typical dress down Friday gear of jeans and T-shirts will be seen as stylish.

I’ve also noticed dresses that look like nighties. My youngest daughter wears one - it’s shaped like a lamp shade and about as flattering as a bin bag.

Some people have suggested that the high cost of clothing has sparked the trend to wear bedclothes in public, but you can still buy budget clobber if you shop around and charity shops have some great gear.

What’s the next step? It’s fairly warm at the moment - why not discard clothing altogether like primitive Amazonian tribes?

It is interesting that men haven’t latched on to this fad, especially after David Cameron admitted that he worked in his pyjamas (albeit at home, not around the Cabinet table). I would say that men had more sense, but they are guilty of the worst look to hit the high street since tights and cod piece: low-slung jeans with half an acre of underpants poking out at the top. Women may commit many a fashion faux pas, particularly with nightwear-as-daywear, but they would never, ever, stoop this low.
