Speaking from personal experience, 2017 was a challenging year. It was bookended by two major events that would change my world for ever. In January I turned 50 (for those who have yet to hit the half-century milestone, let me clarify one thing: age is not just a number) and in December, having been a Londoner for more than 30 years, I moved to the Kent coast in pursuit of a more rewarding and peaceful existence. OK, so at first glance you may well say the two are obviously intrinsically linked. Fair enough. As we get older, we all hanker after a slower pace of life, right? Correct. But the collision of these two events opened a can of worms that I, for one, didn’t see coming.

Men entering their 50s fall into one of two camps: those who have given up, and those who don’t know when to give up

It was time to downsize and, in the interests of both age-appropriateness and to avoid having to book an even bigger removal truck, to edit my out-of-control wardrobe. Working as a fashion editor for more than three decades comes with a whole lot of baggage, quite literally. There is a never-ending pressure to keep up with trends. And it comes at a price if, like me, you are a hoarder – and, in my experience, most men are. After four days dividing up my spoils into “action” piles – one to keep, one for charity, one to re-home, one to sell on eBay – it became clear to me that 50 was not the new 40. It was, traumatically, the finishing line for half of what I owned and, if I am brutally honest, was still wearing.

Crossing over to the wrong side of a half-centenary turns out to be a pivotal junction: you are forced to make decisions on what you should not, as opposed to should, be wearing. A lot of men entering their 50s fall into one of two camps (with a minority bridging the divide): those who have given up, and those who don’t know when to give it up, with the old me falling uncomfortably into the latter. I get that now.

First to hit the deck were my combat trousers, which seem to breed if left alone in a dark closet. I lived in combats through the 1990s and 2000s, quietly phasing them out and only giving them the odd guest appearance in recent years. In fact, any trousers that are oversized, have too many pockets or zips, or have too much surface decoration are a definite no-no. And while we are on the subject of wardrobe staples that have a military heritage, anything in camouflage print also needs to bow out gracefully.

My advice is to keep things in the trouser department plain and simple, with a casual/formal edge – that’s fashion speak for more laidback than a suit trouser but more presentable than a pyjama. I am thinking here of a classic jean cut made in a luxury fabric, as opposed to denim, or a chino that has a careworn vibe, and isn’t too box-fresh or preppy. Margaret Howell makes a mean trouser (a washed cotton twill chino will set you back about £165) as does the Swedish high-street mecca for basics, Arket, whose trouser offering ranges from £55 to £90 (I’m a big fan of their relaxed hopsack slacks).

Another item I seemed to own in abundance were Converse Jack Purcell sneakers, keeping a pair in almost every conceivable colour. Having spent years thinking these were a more suitable alternative to a trainer for an older man, they suddenly became a warning sign of somebody desperately trying to hang on to their youth. Reaching 50 doesn’t mean it’s the end of the road for sneakers – the way forward is to trade up and opt for a quality pair of non-branded shoes from a make like Common Projects, Harrys of London (you can’t go wrong with the Nimble at £295) or Grenson, all of whom have mastered the smart-shoe-to-sneaker hybrid. You can also, at a push, get away with an Adidas Stan Smith to help soften the corporate edges if you want a sneaker that works with tailoring.

A philosophy to adopt across your entire wardrobe is that less is more (both stylistically and in terms of quantity). Now that the time to follow trends has thankfully come to an end, it is better to have a select number of investment items that cost a bit more and will last longer than a landfill of cheaper alternatives.

Another mistake men make is to hold on to things for decades, in the belief they will come back into fashion. In theory that is true – we are having a bit of a 90s revival as we speak. But note to self: these revivals are intended for a younger generation. The bucket hats, anoraks and fleece track-tops that currently look great on kids should be given a wide berth. You won’t give off the vibe of a man with their finger on the pulse – you will simply look like that guy who got stuck in the Britpop era. Baseball caps (I’m just going to say one thing… Forrest Gump), skinny jeans, parkas and Hawaiian shirts are all also on the “to ditch” list. Channel your inner Richard Burton instead and make friends with rollneck knits, Harrington-style jackets (Oliver Spencer is the master of these), pea coats and softly constructed tweed coats. Private White VC is a brand that knows how to make the latter properly. Comfort is important but doesn’t mean hitting the default switch and wearing age-inappropriate sportswear or, even worse, looking like you have given up on fashion altogether.

Another age-inappropriate alert: anything on an e-commerce website prefixed with the word “Dad” – such as Dad trainers or Dad jeans (cue Balenciaga) – isn’t a green light for you to get the credit card out. The word is used ironically, to describe something your dad would have worn, and should be avoided. The impression you should be giving is a man of the world who has lived and made intelligent and experienced choices: a man who doesn’t need to jump on to every bandwagon, but is in control, happy with his lot, and confident.

Moving to the coast was my choice, turning 50 was inevitable – but at least, wardrobe edit in the bag, I can control how stylishly I decide to live it.

What men should be wearing

Cutting edge

Go for tailoring. Overtly corporate suits should make way for lighter constructed blazers in softer, more casual fabrics. Lacoste makes a great jacket that feels like you are wearing a cardigan (lacoste.com), but still looks the business, as does the own-brand Mr Porter range, Mr P (mrporter.com) which, incidentally, has a great edit across the board for men of a certain age. Navy slim-fit unstructured jersey blazer, £425, Mr P (mrporter.com)

Feet first

Comfortable shoes, as you mature, are a necessity. But getting the balance between casual and formal can be tricky. The rule of thumb is a rubberised sole, with an upper in premium leather. Brands such as Grenson, which has a stellar chestnut-coloured version, or high street minimalist Cos (cosstores.com) have nailed the equilibrium. Hand-painted calf leather sneakers, £170, grenson.com

Don’t sweat it

Rollneck knits in fine-gauge yarns should be at the top of your list of basics. They are a great way to introduce colour into your wardrobe – just be cautious. John Smedley (johnsmedley.com) has a great range, as does good old stalwart Marks & Spencer (marksandspencer.com). Hawley rollneck pullover in sea-island cotton, £145, johnsmedley.com

Chino challenge

Opt for chinos that have been garment-dyed, giving a more lived-in patina. Jigsaw cuts a great fit (jigsaw-online.com), as does Joseph (joseph-fashion.com) if you don’t mind paying a bit. Don’t cut them too short at the ankle though, like the young kids do. Slim-fit stretch chinos, £85, jigsaw-online.com

One-stop shop

For all things age-appropriate head to Oliver Spencer. His timeless clothes nod towards the seasonal trends while keeping hold of the reins, and his stores are a one-stop-shop for us older guys. My favourite piece is the Waltham jacket. Waltham jacket in Keeley Oatmeal, £329, oliverspencer.co.uk

Perfect scents

Any man entering their golden years should invest in a less ‘Gatwick duty-free’ and a more ‘niche’ fragrance. Anything that contains woody notes like vetiver is usually a crowd-pleaser, and classic perfumers such as Creed (creedfragrances.co.uk) or Tom Daxon have iconic products.
