When I think about men’s knitwear, I always pause on one small detail that makes or breaks a piece: the neckline. As someone who’s spent over a decade sourcing, designing, and supplying men’s knitwear for small to mid-sized brands—plus working directly with retail buyers and even custom orders for individuals—I’ve seen how a neckline can turn a basic sweater into something versatile, flattering, and distinctly intentional. A lot of men dismiss this detail as trivial, but anyone who’s ever bought a V-neck only to find it gapes awkwardly at the chest, or a crew neck that rides up too high when they tuck a shirt in, knows there’s real science and art to it. Today, I want to break down the most common necklines in men’s knitwear, talk about their best uses, and why choosing the right one matters more than you might think. Men’s Knitwear
Let’s start with the most ubiquitous: the crew neck. If you’ve ever owned a basic cotton sweater, a lightweight cashmere pullover, or even a thick wool knit for winter, chances are it had a crew neck. What defines a crew neck is its close-fitting, rounded shape that sits just above the collarbone—usually an inch or two below the base of the neck, never so high it chokes or so low it dips. The beauty of the crew neck is its versatility; it’s the workhorse of men’s knitwear. I’ve supplied crew necks to clients for everything from casual weekend layering to office casual looks, and they pair with literally anything: a crisp button-down shirt worn underneath (the classic “button-down under sweater” combo), a plain t-shirt for running errands, or even a thin turtleneck for extra warmth on cold days. That said, not all crew necks are created equal. A common mistake I see brands make is a neckline that’s too wide or too stretchy, which starts to gap after a few wears. As a supplier, I always emphasize a medium-gauge knit for crew necks—enough structure to hold its shape after washing, but soft enough not to feel stiff. We test every batch of crew necks by stretching the neck gently, letting go, and checking for bounce-back; if it stays stretched, it’s not going out the door. Another tip for buyers: if you’re shopping for someone with a longer neck, look for a slightly narrower crew neck to avoid making their neck look elongated, and vice versa for shorter necks— a tiny bit more width on the crew will balance proportions.
Next up, the V-neck. I’ve always loved V-necks for their ability to add a subtle touch of style without being flashy. Unlike the crew neck’s rounded top, the V-neck dips to a point at the base of the collarbone, usually two to three inches below the neck opening. This shape is intentional: the V creates a visual line that elongates the torso, which is why it’s so popular among men who want to balance a broader chest or add a little height to their frame. It’s also a go-to for layering, since it sits neatly over a button-down shirt—no awkward bunching at the neck, and the peeking collar looks polished. That said, the biggest complaint about V-necks is gaping. I’ve had so many buyers come to me after receiving a batch of V-necks where the sides pull away from the chest, revealing too much skin. The fix? The depth of the V and the knit’s tension. A well-made V-neck shouldn’t dip more than three inches below the collarbone for everyday wear; deeper V-necks (think four inches or more) work for formal occasions, but they’re hard to style for most men. We also use a tighter stitch on the sides of V-necks, a trick I learned from a top knit designer I worked with early in my career—this prevents the fabric from stretching too much, so the V stays neat instead of gapping. I’ve supplied V-necks to retail chains and custom clients, and we always get feedback that ours don’t gap, which makes them stand out in a crowded market.
Then there’s the turtleneck, a neckline that’s had a weird journey in men’s fashion: once a staple for sailors and then a symbol of 1960s counterculture, now a go-to for sleek, modern looks. A turtleneck is a long, close-fitting neckband that folds over once (or sometimes twice for extra warmth) around the neck, sitting anywhere from the base of the neck to just below the jawline. There are two main types: the slim-fit turtleneck, which is thin and sits close to the skin, perfect for layering under a blazer, and the chunky turtleneck, made from thick wool or cashmere, ideal for cold winter days. What I love about turtlenecks is their versatility in styling—they can be dressed up with a suit and coat, or dressed down with jeans and sneakers. But again, fit is everything. A turtleneck that’s too tight will feel restrictive, and if you tuck too much of the fold, it will bunch up. Too loose, and it will ride up, leaving your neck exposed. As a supplier, we offer turtlenecks in a range of stretch percentages—7-10% spandex for the slim ones, a little less for the chunky ones—so they move with you, not against you. I also recommend turtlenecks for men who want to add a layer of warmth without bulk; they’re way lighter than a scarf, and look far more polished.
Another neckline that’s growing in popularity, especially in the last few years, is the henley neck. Henleys are a middle ground between a crew neck and a placket shirt, with a short button placket (usually 2-4 buttons) at the center of the neck, instead of a full button-up. In men’s knitwear, henleys are often made from softer, thinner knits, perfect for casual looks. They’re less formal than a crew neck, but not as casual as a full open collar. I’ve supplied henley knit sweaters to clients targeting younger men, as they add a subtle detail that feels modern without being overly fussy. The best part of a henley neck is that you can adjust it: unbutton the top one for a relaxed, weekend vibe, or button it all the way up for something a little put-together. A common mistake here is making the placket too long, which makes the henley look like a half-unbuttoned shirt instead of a sweater. We keep our knit henley plackets short, no more than four buttons, to keep the shape neat.
Then there’s the mock neck, sometimes called a half-turtleneck. It’s shorter than a full turtleneck, sitting just a half-inch above the collarbone, with a very close, snug fit around the neck. It’s a middle ground between the crew neck and the turtleneck—warm enough for cool weather, but not as restrictive as a turtleneck. Mock necks are great for men who want the polished look of a turtleneck but don’t like the feel of fabric wrapped around their neck all day. I’ve noticed more demand for mock necks in recent years, especially among men who work in offices that allow casual dress codes; they look sleek under a blazer, but are comfortable enough to wear on a commute or after work. A lot of brands mix up mock necks with high crew necks, but there’s a key difference: a crew neck is shaped like a wide arc, while a mock neck is a straight, narrow cylinder around the neck. That straight shape is what gives it that modern, tailored look.
I also want to mention the scoop neck, though it’s less common in men’s knitwear than women’s. That said, in recent years, we’ve seen a small but steady demand for slightly deeper scoop necks in lightweight knits, especially among men who prefer a more relaxed, casual style. The scoop neck dips lower than a crew neck, in a gentle arc, and usually sits about an inch below the collarbone. It’s a good option for men with broader shoulders, as the lower dip balances out the upper body, and it looks great paired with a thin chain necklace for a subtle accessory. That said, we only make scoop necks for lighter gauge knits; heavy wool would look too drapey and unstructured for this neckline.
Now, let’s talk about what I always tell buyers when they come to me for their knitwear orders: the neckline is the first thing someone notices when they look at a sweater, and it’s the last thing that feels comfortable when you wear it. Too many brands cut corners on necklines to save cost—using cheap yarn with no stretch, cutting the neck too wide or too deep, or not finishing the edges properly. As a supplier, we prioritize neckline construction because we know that a sweater’s lifespan often depends on how well the neck holds up. A crew neck that stretches out after two washes is going to get tossed in a drawer, but a well-made neckline will last for years, become a favorite go-to piece.
When I work with a new client, I always ask three questions about their target customer to narrow down the best neckline: Where will they wear this? (Office, casual outings, formal events?) What’s their body type? (Shorter neck, broader chest, etc?) What’s their personal style? A young guy shopping for weekend casual will probably love a henley or a relaxed crew neck, while a middle-aged professional might prefer a turtleneck or a V-neck for layering under a blazer. For example, last year we supplied a batch of slim-fit turtlenecks to a client that specializes in office casual; they told me the feedback from their customers was that the turtlenecks were “polished but not stuffy,” which was exactly what they were going for.
If you’re a retailer or a brand looking to source men’s knitwear, or an individual looking for custom pieces that fit perfectly, think about necklines not as an afterthought, but as a core part of the design. A well-chosen neckline can elevate a simple sweater from basic to versatile, flattering, and truly wearable.
At the end of the day, knitwear is about comfort and style, and the neckline is where those two meet. It’s the part that touches your skin all day, the part that frames your face, and the part that sets the tone for the entire piece. Whether you’re reaching for a crew neck for a lazy Sunday, a V-neck for a workday layering, or a turtleneck for a date night, the right neckline makes all the difference.
