How to Choose V-Necks for Skinny Men: 6 Practical Tips

1. Choose the Depth of the V for the Effect You Want

A shallow to medium V-neck, one that opens just enough to show a shirt collar and the knot of a tie, keeps more knit across the chest.

A shallower V is often suggested for a slim build because its wider angle is meant to lead the eye towards the shoulders rather than down the centre of the body.

A deep V shows more shirt or skin and makes a longer, narrower opening.

It draws the eye down the centre of the chest, so if you want more emphasis on width, a shallower V is the usual suggestion; if you like a longer line, or you wear the V-neck open over a T-shirt, a deeper V is a legitimate choice.

Other guides on The VOU suggest a deeper V for readers with a fuller middle for that same lengthening reason.

There is no correct depth in inches.

Try the V-neck on over the shirt you plan to wear and check where the opening sits in a mirror.

2. Consider Knit Weight and Texture

Mid-weight knits in merino wool, lambswool or a firm cotton have more body than very fine knits.

They hold their own shape instead of following every contour, which many slim men prefer when the V-neck is worn on its own.

Very fine knits are the other option.

John Smedley’s Sea Island cotton knits, for example, are made at 30 gauge, a fine and smooth knit that is light rather than heavy.

A fine knit sits flat under a jacket and suits warm offices; if it clings when worn alone, a mid-weight knit is the alternative.

Textured knits such as cable, rib or a chunky lambswool add surface interest and some bulk.

Wear them if you like a fuller look through the chest, and check that the extra bulk does not make the sleeves or body too wide.

3. Wear a Fit That Skims, or Go Oversized on Purpose

Look for a V-neck that skims the body: it sits close without pulling across the chest, does not cling at the waist and does not ride up when you raise your arms.

The sleeves should reach the wrist bone without bunching.

On a classic knit with set-in sleeves, the shoulder seam usually sits at the edge of your shoulder.

A dropped shoulder is a deliberate relaxed style rather than a fault, so decide which look you want before judging the fit.

A very tight knit shows the outline underneath, and a very loose one can look borrowed.

If you like a relaxed, oversized look, choose it on purpose and keep the trousers and shoes in proportion.

Knitwear is harder to alter than a shirt, so it is worth trying on several sizes and makers.

4. Layer Under a Jacket

A fine or mid-weight V-neck under a blazer or sports jacket adds a layer of colour and texture between the shirt and the jacket.

A jacket with some shoulder structure is meant to add definition at the shoulders, and a softer jacket gives a more relaxed line; both work with a V-neck.

Keep the V-neck thin enough for the jacket to button without strain and for the sleeves to move freely.

Chunky knits are better worn on their own or under a coat with room for them.

5. Choose a Shirt Collar That Sits Well Inside the V

A spread or cutaway collar opens outward towards the shoulders, which many people find adds a little width at the top of the outfit, and its points tuck neatly under the edges of the V.

A button-down collar also works well under a V-neck and stays in place without a tie.

Band collars and collarless shirts give a cleaner, more casual neckline.

They are a matter of style rather than something a slim build needs to avoid.

Check that the collar points sit under the edges of the V rather than poking over the knit.

6. Choose Pattern and Colour by the Look You Want

Horizontal stripes are often suggested for adding width across the chest.

Studies of striped clothing have found effects in both directions, and some found horizontal stripes made the wearer look thinner rather than wider; none settles a rule, so wear stripes because you like them rather than as a fix.

Vertical stripes and patterned knits such as Missoni’s zigzags are equally open to you.

Solid colours are the most versatile.

Mid and dark tones such as navy, grey and bottle green pair easily with most shirts and trousers; lighter colours such as cream, pale grey or light blue bring more attention to the upper body, which some slim men prefer.

Both approaches work, and our other guides for slim builds discuss lighter shades in more detail.

Textured knits add interest in a plain colour if you prefer not to wear pattern.

The Final Verdict

A V-neck suits a slim or narrow build when it fits well and its depth, knit and colour give the look you want.

Start with the fit at the shoulder, body and hem, then choose a shallower or deeper V, a fine or mid-weight knit and the shirt you will wear underneath.

None of these choices is compulsory; compare them in a mirror and keep what you like wearing.
