The right necklace for your face shape depends on three things: length, metal colour and material. Length creates a line that frames the face and neck, the metal colour should blend with your skin's undertone, and the material needs to be kind to your skin, especially if jewellery tends to make you itch.
This article covers how to choose necklace length, metal colour for your undertone, the metals dermatologists suggest for sensitive skin, and Kira's real picks from one selfie.
Necklace length and how it frames the face
Jewellers commonly name lengths such as choker (the shortest, around the neck), princess (about 45 cm, at the collarbone) and matinee (longer, above the chest). As a general styling guide:
- Long or Y-pendant necklaces create a vertical line, so the face and neck look longer.
- Chokers create a horizontal line at the neck, which helps balance a long face or a long neck.
- Curved matinee necklaces look elegant and pair well with round-neck tops.
These are styling guidelines, not fixed rules. The easiest way to see the result is to try it on a photo of your own face.
Metal colour for your undertone
Warm undertones usually blend with yellow gold and rose gold, while cool undertones often look bright with silver and white gold. Not sure of your undertone? Read how to find your skin undertone.
Kira's real result for necklaces
Here is Kira's real result for the question "which necklace suits me?" from one selfie of an AI model:

For this model, Kira read an oval face, a medium neck and a warm undertone. The picks:
- Gold Y-Pendant Necklace (princess, 45 cm), because it creates a longer look.
- Rose Gold Choker, because it balances the face shape.
- Gold Curved Necklace (matinee), because it looks elegant.
- Silver Chain Necklace to avoid, because it suits a warm undertone less well.
Kira's tip: pair the necklace with a round neckline. The preview above was made by Kira directly on the model's photo, so you can see the difference before you buy.
Itchy skin after wearing a necklace? Check the metal

According to the American Academy of Dermatology, nickel is one of the most common causes of allergic contact dermatitis, a rash or irritation caused by touching an allergen. A nickel allergy often develops from jewellery containing nickel. Earrings and watches are the biggest culprits, but necklaces, rings and bracelets containing nickel can also trigger symptoms.
AAD dermatologists recommend wearing only jewellery that is nickel-free or hypoallergenic, or made from surgical-grade stainless steel, 18-, 22- or 24-karat yellow gold, pure sterling silver or platinum. If a rash does not improve, see a dermatologist. Does your skin react easily? Also read skin care for sensitive skin.
Pair it with other accessories
A necklace looks best when your earrings and neckline work with it. See earring styles for your face shape and clothing colours for tan skin.

Frequently asked questions
How do I choose a necklace for my face shape?
Look at length, metal colour and material. Long or Y-pendant necklaces make the face look longer, chokers balance a long face, and the metal colour should blend with your skin's undertone. The easiest way to decide is to see a preview of the necklace on a photo of your own face.
Which necklace suits an oval face?
In Kira's example for an oval face with a warm undertone, the picks were a Gold Y-Pendant Necklace at princess length of 45 cm, a Rose Gold Choker and a Gold Curved Necklace at matinee length. A Silver Chain Necklace was marked to avoid because it suited the model's warm undertone less well.
Why does my neck itch after wearing a necklace?
A common cause is a nickel allergy. According to the American Academy of Dermatology, nickel is one of the most common causes of allergic contact dermatitis, and jewellery containing nickel, including necklaces, can trigger a rash. Choose nickel-free or hypoallergenic jewellery, and see a dermatologist if the rash does not improve.
Which necklace metals are safe for sensitive skin?
Dermatologists from the American Academy of Dermatology recommend jewellery labelled nickel-free or hypoallergenic, or made from surgical-grade stainless steel, 18-, 22- or 24-karat yellow gold, pure sterling silver or platinum. These choices help avoid the nickel exposure that often triggers a rash on sensitive skin.
