DIAMOND BODY SHAPE

Collars

Chosen to flatter your diamond shape — framing the neckline to balance your shape

Where it lands

Each style card shows where a piece finishes on the body. Look for your narrow points: just below the knee, above the ankle bone, and your natural waist. Hems that land there follow your natural lines. Labels are cut for one average height, so always check the hem against your landmarks.

Earrings

Earrings sit right beside your face, so they’re one of the quickest ways to draw the eye and shape how your features read. Studs, drops and hoops each do something different — lengthening, softening, or adding width exactly where it flatters your face shape. There’s no single “right” earring, only the shapes that bring your own proportions into balance. Your Best picks lead with the styles that suit you most naturally; Alt gives you room to experiment; Least simply shows what to wear with a little more thought.

A few words on care: store pairs together so you never lose one, give posts and hooks a gentle wipe to keep skin happy, and choose hypoallergenic metals if your ears are sensitive. Sterling silver and gold last for years when kept dry and away from perfume and hairspray — clean them now and then with a soft cloth.

Wear what lifts your face, and your mood.
