What Necklace to Wear With a Crew Neck Sweater (Lengths and Weights)

“A crew neck is a frame. Put a necklace on the frame's edge and it looks like it's slipped. Put it above, inside the frame, or well below, on the knit, and it looks placed. That's the whole secret.”Her take

The two lengths that work with a crew neck

A crew neck sits at the base of the neck, so a necklace has two good places to go. Above the neckline, a collar or short chain of about 14 to 16 inches sits on the skin inside the circle of the knit; a 16-inch chain can graze a high crew, so check it. Below the neckline, a long chain or pendant of about 24 inches or more lies on the sweater itself, somewhere between the collarbone and the bust.

Necks, bodies and necklines vary, so treat these as starting points and check in a mirror. The length to avoid is the one that falls right on or just under the ribbed edge, often somewhere around 18 inches, the length that usually sits at the collarbone; it gets pushed around, half hidden and half showing. If your chain has an extender, try it at each setting with the sweater on.

• Above: a short chain, a small pendant at the hollow of the throat, a strand of pearls worn close.
• Below: a long pendant, a long fine chain, a lariat or a long chain with a charm.

Match the necklace weight to the knit

A fine merino or cashmere crew neck is thin and smooth, so delicate chains and small pendants show up well against it. A chunky cable or heavy wool knit swallows fine jewelry. A thin chain on a big cable knit simply disappears.

With chunky knits, choose something with presence: a thicker chain, a larger pendant, a long chain with a medallion, or a bold strand of beads. With fine knits, keep it delicate or medium.

How to layer necklaces over a sweater

Two necklaces is usually the most a sweater needs. Wear one short above the neckline and one long below it, so the knit sits between them like a gap in the layering. This keeps the necklaces apart and stops them tangling.

If both are long, space them at least two inches apart and give them different weights or textures, a fine chain and a heavier one, so they don't blur together on the knit.

Pendants, pearls and colors

A long pendant over a crew neck draws the eye down and lengthens the neck and torso, which is useful with a high, closed neckline. Choose a pendant big enough to stand out against the knit's texture.

Pearls look modern over a crew neck when worn short, close above the neckline, or as a long rope over the sweater. Metal color can follow the sweater: yellow gold glows against camel, cream and navy; silver looks crisp against gray, black and icy blue.

How to stop necklaces snagging a sweater

Loose and open knits catch on prong-set stones, rough or textured links and open jump rings. Run the necklace over the back of your hand before wearing it; if it catches on skin, it will catch on wool.

Smooth, closed chains like box, snake, rope and cable chains, and bezel-set stones are the safest over knits. Take necklaces off before pulling a sweater over your head, so the chain doesn't pull a loop or break.

When to wear a collared shirt underneath instead

If the sweater is in a busy pattern or a very textured knit, the collar of a shirt underneath can be the accessory instead of a necklace. Add earrings rather than a chain.

If you do wear both, a short chain under the shirt collar or a long pendant over the sweater both work; just avoid a necklace that fights the collar for the same space.

Questions people ask

The takeaway

Above the neckline or well below it, never on the edge; weight to match the knit; two necklaces at most; smooth chains to avoid snags.
