The ??79 Marks and Spencer coat that everyone will be wearing during London Fashion Week

No fewer than five editors on the Telegraph Fashion team own, and still love to regularly wear, a very particular model of khaki-coloured trench coat.If, by accident, we all happen to reach for said jacket in the morning, we arrive in the office dressed as a troop of army generals, orperhaps more fittingly, retro hacks who look as though they havemarched in from Fleet Street, notebooks poised.That said,we all manage to style it our own way.

But would it surprise you to know that the coat in question is from Marks and Spencer?Our original,the ???Frances???, was bought in April 2016 for ??89, and was a part of Alexa Chung???s ???Archive by Alexa??? edit for the British high street institution - a collection that shifted 20,000 units by 4:30pm on the day of its launch.The street style set liked to flash the plaid lining by turning up their cuffs, and its proportions were spot on; long enough to cover a mid-length skirt while showing a hint of a colourful hem, and nipped so that it didn???t drown your figure.

Savvy then, that M&S have brought it back in two new colourways, on top of the original green, for autumn - and for ??10 less, at that.She???s no longer called Frances, instead being dubbed the ???Pure Cotton Trench Coat with Stormwear???(snooze) but all her features are the same.

Pure Cotton Trench Coat with Stormwear, ??79, Marks and Spencer

Chung didn???t design the original, her brief for the Archive by Alexa edit was to plunder the M&S design archives and pull out anything that appealed to her famously good taste.???Taking inspiration from a navy, 1950s gabardine raincoat, this double breasted trench has an updated colour and style,???M&S said at the time.???Known for their incredibly hardwearing exterior, our raincoats were once described "second to none" so it"s no surprise Alexa picked this as a key archive piece.???

Marks and Spencer sells 1.1 million coats on an average autumn winter season - five per minute, they estimate.For autumn 2017, their heroes include a cashmere blend crombie for ??119 and a pitch-perfect parka with drawstring waist for ??65.But the one that the editors who value their quality classics will be reaching for as they head out to shows?Meet the Frances 2.0.
