Many people feel that if their neck is short or thick (or both) that it excludes them from wearing jewellery near their face, but this is not so.
Look for necklaces that are to your first balance point or longer (double that length is great too). Avoid your second balance point (the high one). Look for longer pendants and necklaces that drop to mid-chest or longer. Layers of long necklaces that create a flattering horizontal really flatter. Look for larger scale pendants but not on heavy chains, instead on a finer chain so the focal point is the pendant rather than what it’s attached to. Earrings can be great, avoid wide chandeliers as they will further add bulk, instead look for studs or drop earrings that are about 3cm long (never past your chin) that are slim in style such as hoops and tear drops. Have you considered brooches? They can be worn on the collars of your jackets and won’t have that strangling effect. If you have necklaces that you love but feel they’re too short, get an extender put on the fastening, or try a different length chain if possible. Why not draw attention to your hands with bracelets and bangles, cocktail rings and funky watches.
