Funny what those trends throw up, isn’t it? The humble men's sweater vest, or knitted vest depending on your terminology, is back in the mix. Thought it was resigned to cliched jokes about nerds on TV shows? Think again. Harry Styles has been wearing knitted vests for over a year now. He was especially fond of one with flowers on for a while. He walked so you can run.

Men’s sweater vests have come a long way. They’re not those itchy, heavy gauge potato sacks with arm holes that you might remember from yesteryear. They’re boxy now, they’re preppy, they’re for wearing when it’s warm out or for adding another layer underneath if it’s cold. They’re channelling '70s prints in a cool way and they’re coming at you from high and low, be it Prada or Uniqlo.

Of course you need one. So we’ve pulled together a few of the best knitted vests for men right now, with a helpful styling primer on how to wear one.

There’s a lot of inspiration out there when it comes to knitted vests for men. Harry Styles for instance looks best wearing his with a high waisted wide-leg trouser or flare, with a large collar shirt underneath, slightly unbuttoned with rolled up sleeves. All very '70s but also not at all as out there as his other outfits.

You don’t have to don the flares per say, but you can channel Harry with a notably more vibrant sweater vest with a relatively simple white or neutral coloured shirt underneath. The shirt and knitted vest combo is an obvious one. This can be dressed up, with the layering element aiding suiting or dressed down with a simple trouser and sandal. Very Universidad prep.

Ryan Gosling is a good reference too. He’s been known to don a knitted vest with slight patterning over a white T-shirt. He’s also been spotted with one underneath a denim jacket. Tyler The Creator goes one further, channelling what can only be described as skateprep via the golf course with a vest and T-shirt combo above simple shorts and loafers with white socks.

The aim really is to work a knitted vest’s layering abilities to your advantage, let the print on the vest do the heavy lifting and make sure there’s subtle, but not overbearing contrast against what you’re wearing above or underneath.

You’re going to see a lot of extra fine merino wool knitwear knocking about the men’s sweater vest arena, and rightly so. You want one to feel soft and effortless, comfortable to the touch (skin even, if you’re wearing it without anything underneath) with the benefits of breathability. Don’t underestimate the breathability of premium quality merino wool. Artknit Studios' iteration is a V-neck, rib stitch number with ribbed collar, hem and armholes. Available in four natural tones, and using premium Italian heritage craftsmanship it’s great for wearing over a simple white tee and some navy or beige pleated trousers.

We’ve said it before and we’ll say it again. A Day’s March's overshirts are some of the best in the biz. They are a one-stop shop when it comes to overshirts. But also, come for the overshirts, stay for the men’s sweater vests because they’re equally as good. Timeless, well-crafted basics are what the brand is known for and the sweater vests follow the theme. Available in three natural and easy to style colours, the V-neck Wigtown vests are made from 100% lambswool with thin ribbing at the neck and hem. As effortless over a long-sleeve polo shirt as under a deconstructed jacket.

See, knitted vests for men are miles away from Wallace and Gromit. I mean look at this from Closed. Look at that fantastic bold V-neck and prominent stitching. Look how great it looks on top of a plain white t-shirt but also imagine how warm and comfortable that would be as summer moves to autumn. Made from a soft wool cotton mix, this medium weight knit has a fisherman’s rib with openwork details around the shoulder and ribbed cuffs. It’s casual and that bold contrast V-neck is gagging to be set off against a great jacket.

Cos is the sort of place that you can rely on for a solid sweater vest. Sweater vests are premium Cos. The brand’s V-neck knitted vest in prominent rust red is the ideal pop of colour to be contrasted against dark trousers and a trademark chunky sole Cos-complimenting brogue. White Oxford shirt or T-shirt underneath, your choice. Made from a sustainably-crafted cotton-wool blend, mouline twist yarn gives it that chunky melange effect. A boxy, relaxed fit lends it to layering.

Of course you don’t need to spend extortionate amounts on a knitted vest for men. Uniqlo do a solid crew neck version that’s available in four highly workable colours. Perfect for dressing up or down. The looser knit gives the vest a slightly chunkier look whilst thick yarn also bolsters the chunky look but leaves the garment light and comfortable. Roomy, it’s a great option for a slouchier fit, matching a wider, looser fit trouser with a T-shirt underneath.

Now we’re talking. Rainbow pattern. Harry Styles would be proud. You’ve seen the more refined, safe styles but you want to go big so you’ve got your eye on this unisex rainbow-striped number from Acne Studios. This crochet wool vest is made from certified wool and packs a chunky old-school, DIY made by your grandma look. With a regular fit, wear it over a subtle patterned shirt and do or do not pair it with some out there flairs. It depends how brave you’re feeling.

Last but not least a bank-busting sleeveless number from striped fashion powerhouse Thom Browne. The brand’s cashmere 4-bar shell top is all kinds of luxury, with that all important four line striped detail as well as a crew neck and buttoned sides. Slim-fitting and sleek, wear this men's sweater vest over a white cotton shirt and let it do the talking. Made in Scotland from 100% cashmere.
