THE NECKLACE LENGTH GUIDE NOBODY ELSE WILL WRITE

A honest conversation about what actually works on real bodies.
Every necklace length guide on the internet will tell you the same things. Choker. Princess. Matinee. Opera. A neat diagram showing where each one sits. A polite suggestion that longer lengths elongate the neck.
None of them will tell you what actually happens when you put a necklace on your actual body and go about your actual day.
This one will.
Let's start with the thing nobody mentions
If you have a fuller bust you already know about the lost necklace problem. The pendant that falls exactly where you didn't want it to fall. The chain that disappears into the cleavage. The piece that gets caught on the wrong side of a bra underwire and causes damage to both the jewellery and the lingerie.
This is not a small thing. It happens to a significant proportion of women and precisely nobody in the jewellery industry talks about it because apparently it's not something we discuss.
We're discussing it.
The solution is length and weight considered together. A pendant that falls into the cleavage is usually sitting on a chain that's too long for your proportions. The fix is not to stop wearing pendants. The fix is to go shorter. A necklace that sits at the collarbone rather than falling below the bust keeps the pendant exactly where it can be seen and enjoyed rather than lost somewhere it absolutely shouldn't be.
For layering on a fuller bust the principle is to start with one piece that sits safely at the collarbone and build from there. Add something longer if you want layers but keep it over a shirt or higher neckline where it has room to move without getting lost. The shortest piece does the framing. The longer pieces add depth without disappearing anywhere they shouldn't.
The honest truth about chokers
Chokers are complicated and anyone who tells you otherwise is not paying attention.
The received wisdom says chokers work on longer necks and should be avoided on shorter ones. Like most received wisdom this is approximately half true.
Here's the fuller picture.
A choker on a shorter neck can look extraordinary if the person wearing it has the confidence to carry it. I have seen a multi strand pearl choker look absolutely magnificent on a woman with a very full neck and a very large frame. It worked because she wore it as if it was exactly right. Which it was.
Confidence is not a cliché in this context. It's a genuine style variable. A piece worn with certainty reads differently than the same piece worn with doubt.
That said. There are practical considerations that confidence alone cannot solve.
If you are of a certain age and prone to hot flushes a choker will make your life significantly worse. There is nothing glamorous about feeling strangled while your temperature rises. This is not a style opinion. This is physiology. A choker sits against the skin of the neck with no airflow. If your neck runs hot choose something that sits lower and gives you room to breathe. Your jewellery should not make you more uncomfortable than you already are.
Younger wearers tend to carry chokers beautifully particularly as part of a layered look where the choker anchors a longer chain beneath it. The combination of something tight at the neck and something that falls lower creates a deliberate contrast that works at any neckline.
The neckline conversation
Your necklace and your neckline are in a relationship whether you acknowledge it or not. Here's how to make it a good one.
Round neck or crew neck — the necklace needs to sit above the neckline or below it. A chain that disappears under a crew neck and reappears at the collarbone looks unfinished. Either go shorter and sit above the fabric or go longer and let the pendant fall below it onto your chest.
V neck — one of the most cooperative necklines for jewellery. A pendant that follows the V line draws the eye down and elongates. A piece that sits higher than the V creates a deliberate contrast. Both work. Choose based on whether you want the eye to travel down or stay at the face.
Open collar or shirt — enormous flexibility here. The open collar frames whatever sits in it. A single pendant at the collarbone in an open linen shirt is one of the most effortlessly right combinations in jewellery. This is the neckline that makes the Porini pieces look their best.
High neck or polo — the necklace goes over the top or doesn't happen. A fine chain layered over a high neck can look considered and deliberate. A pendant fighting with a polo neck collar looks like an accident. If you love your high necks invest in earrings and let the necklace rest.
Strapless or low cut — the collarbone is the star. A piece that sits right at the collarbone frames it perfectly. This is the occasion for the Tahitian pearl pendant, the single gemstone drop, the piece with genuine presence. The neckline is doing the work of drawing attention upward. The jewellery just needs to be there to receive it.
The almost universal length
After forty years of making necklaces and watching them on real women there is one length that works on almost everyone.
Forty five centimetres.
It sits at or just above the collarbone on most frames. It works with an open collar, a V neck and a round neck. It's long enough to have presence and short enough to stay out of trouble.
The caveat is weight and style. A very fine chain at forty five centimetres reads completely differently to a heavy chain at the same length. A large pendant pulls the length down. A small pendant lets it sit exactly where it should.
Use forty five centimetres as your starting point and adjust from there based on what the piece is doing and where your proportions want it to sit.
On layering
Layering necklaces is one of those things that looks effortless on everyone who does it well and completely chaotic on everyone who does it wrong. The difference is usually one thing.
Each layer needs to be a different length with enough space between them that they read as distinct pieces rather than a tangle.
A minimum of five centimetres between each layer gives them room to sit separately. The pieces themselves should be different in character. A fine chain with a fine chain creates nothing. A fine chain with a slightly heavier chain with a pendant creates a conversation.
Start with the longest piece. Add upward. Stop before it gets complicated.
And on a fuller bust as we established, start long, work upward, keep the longer layers over fabric where they have somewhere to be.
The honest summary
Wear what feels right on your actual body in your actual life. The diagrams and the rules are a starting point not a sentence.
Go longer if you have a fuller bust and avoid the cleavage problem entirely. Skip the choker if you run hot. Use forty five centimetres as your anchor length and adjust from there. Let your neckline tell you where the necklace wants to sit.
And if something you love isn't sitting quite right come and talk to us. Forty years of making means forty years of watching pieces on real bodies. We have opinions and we'll share them honestly.
