The difference between Steve Jobs and Bill Gates was wrapped around their necks. Throughout the 1990s, when the pair were at loggerheads to own the home computing industry, Apple’s impresario presented a succession of groundbreaking designs wearing his trademark Issey Miyake roll neck. At Microsoft, Gates wore V-neck knits with all the elan of an Excel spreadsheet.

Thus has it ever been. Fashion loves to keep a man guessing, but for a long time now the one thing you haven’t had to agonise over is your neckline. The rule was simple: crew necks are good; V-necks are bad. Depending on its depth, the V was exclusively for part-time golfers or full-time LADS.

So consider us v. shocked to see it sashaying down the runway this season. “Though the crew neck has dominated menswear for some time, we’ve seen a shift towards the V-neckline recently,” says Simon Chilvers, menswear style director at MatchesFashion. “Prada and Lanvin championed this look at their AW17 presentations, worn layered over shirting or simply under a blazer.” Both tapped a change that had been slowly percolating for a couple of years, with Raf Simons’ oversized cricket sweaters and Gucci doing some frankly unwearable things with sweater vests. But suddenly, they’ve become fashion without the capital F.

“The first look straight out of the gate at Prada featured a grey V-neck sweater,” says stylist Eric Down, who has dressed the likes of David Gandy, Tinie Tempah and Chris Hemsworth. “Entirely unassuming, but ultra-desirable, this is the building block of a classicist wardrobe. And where Mrs Prada goes, everyone follows.” It also embodies that odd tension where something is so unfashionable that it becomes fashionable again (case in point: bum bags).

“The V-neck reflects a desire for more normcore dressing,” says Down. “In an age of such global political uncertainty, it is unsurprising that fashion turns to the familiar and the comforting.” And nothing’s more comforting than knitwear.

Of course, the risk with the V-neck – alongside corduroy, quarter-zip fleeces and ugly trainers – is that without at least some flair, you risk looking like your dad, rather than ‘inspired by’ him. Hence why this season’s V-necks aren’t just luxed-up versions of those that fill the fustier sections of any department store.

For a start, the gorges are longer. That means there’s more wiggle room with what’s underneath; now, you can think beyond shirt and tie for work, shirt without a tie for drinks after. But they’re not deep enough to rival lads-on-tour navel-grazers. “The AW17 V-neck is unassuming,” says Down. “It is simple, considered, with clean lines, in tactile fabrics that state the case for subtlety. Not a word you’ll find on the casting notes for Love Island.”

It’s also effortless. Menswear en masse is loosening up and this reinvention of the V-neck taps into that movement. At Louis Vuitton, they were shown half-tucked into belted suit trousers; at Dries Van Noten, they were boxy and paired with jeans, for a look that seemed more suited to a weekend on the town than on the links.

5 Fresh Ways To Wear A V-Neck

The new rule of V-necks is that there are no rules. They’re not just for Bill Gates and golf clubs, or at the other extreme, Michael Douglas gyrating his way around Sharon Stone in Basic Instinct. The V has won an unlikely fashion victory. And the opportunities to wear one are boundless. Here are five of our favourite ways to style them this season.

Suit Up

Long the go-to for SpAds and the only guy at work who knows how to fix a paper jam, a V-neck is more than just a way to warm up when you’ve got to wear a suit to work.

Just don’t be tempted to colour too far outside the lines, literally – V-necks may come in a rainbow of shades, but it’s best to keep things basic and let the neckline do the lifting. “Classic combos of white cotton shirts and grey or navy sweaters with a well tailored trouser will never fail,” says Down.

The Time Machine

One of this season’s easiest ways to look fashion-forward is to pair its two trending necklines: the roll neck popped out from beneath a V.

“Anyone can pull this off, but it is quite a 1970s vibe,” says Down. “For a modern take, go full Jil Sander with an icy cream or white colour roll neck under a blue or grey V-neck, without accessories and over grey wool trousers.

For something a bit more tongue-in-chic, clash a mustard roll neck with a maroon V-neck and sling a brown leather blouson on top.” Just be prepared to fend off the odd Alan Partridge comment.

Texture Mixing

If AW17 is about anything, it’s about texture. The best V-necks come in buttery wools that add coziness and depth to an outfit, which makes them the perfect foil for the season’s other trending fabric. “Corduroy is big for AW17,” says Down, “so try a cord trouser in a soft butterscotch or honey colour.”

If that all feels a little too geographer teacher for you, consider toughening up the V-neck with a leather biker jacket or wool overcoat. The former helps steer the once IT-department staple in a more casual, rebellious direction; while the latter in a houndstooth or check can break up flat colours and add add a touch of personality.

The Cricket Sweater

The V-surgence is at least partly thanks to David Beckham and his co-ownership of heritage brand Kent & Curwen. The British label invented the cricket sweater in the 1930s and kickstarted the first V-neck trend.

Eighty-odd years on, creative director Daniel Kearns has reimagined the OG version in luxury wools with subtly striped collars, both in classic white and, if that feels too fancy dress, deep navy. They look best with tailored trousers or jeans and an overcoat, with or without anything underneath. Consider it athleisure for people who’d never dignify the word.

With Bare Skin

On which note, this season Zegna rescued the V-neck’s sexier side from the Love Island clones. “It showed collarless, V-neck button-front shirts that looked ultra-modern under blazers and suits,” says Down.

If you’re blessed with Gosling-like looks, then you can steal his Riviera moves and style a V-necked knit au naturel. But to toe the fine line between class and lechery, stick to muted shades and fine fabrics, like wool-silk blends, merino or cashmere. And just take care not to wink at anyone.

Merino Wool Jumper

Despite having a rough go of it the past couple of winters, the one thing that has kept the V-neck alive (as far as knitwear goes, at least) is the enduring appeal of merino wool. Soft, lightweight and temperature-regulating, it’s redeeming qualities go far beyond being a more affordable alternative to cashmere.

The material, shorn from the sheep of the same name, is right at home as a V-neck. Its breathable nature means it can easily slot over a shirt without causing you to sweat through on the commute.

As well as the classic neutral shades, consider giving jewel tones like emerald green a go, which can break up an otherwise unenterprising outfit.

Cricket Sweater

Though it may not rank as highly in the world of stylish sports as tennis, cricket’s contribution to the menswear world is no less gratefully received.

A close relation of the cable knit sweater (another essential knit for the autumn/winter months), this season the piece has made the transition from the field to the front row.

Styles rendered in thick, insulating wool are perfect for days in the depth of winter, while those spun from lighter weight cotton are ideal for tricky-to-dress-for transitional days or layering over something equally preppy, such as an Oxford shirt.

Zip-Neck Jumper

You’d have to have been living under a soundproof rock not to have noticed the rise of athletic-inspired apparel in men’s wardrobes over the last few years.

A slightly more elevated alternative to the track-top, a zip-neck sweater – ideally in a premium material like merino wool or cashmere – is an ideal way to buy into the V-neck trend without fully committing.

Try yours worn unzipped with a bit of white T-shirt showing or layer under a suit jacket to bring a sporty edge to your office attire.
