Shapes
Now there are a several different face shapes, but we are going to stick with the main four: oval, round, square/rectangular, and heart-shaped face. An oval face is longer than wide and has curved edges…no straight lines. A round face has equal distance all around with the nose as a center point. Square and rectangular faces are basically the same except a square’s distance from forehead to chin is the same as cheek to cheek. A rectangular face is longer than wide. Last, a heart-shaped face is wider at the top (the eyes, cheeks, and forehead) and then comes to a “point” at the chin. They normally have sharper features.
If you still can’t decide what shape your face is, ask a friend to help you!
–Oval: 
Necklaces: You can wear anything. From a choker to a necklace that comes to a “v” to a long strand of beads, you can pull it off…
Earrings: Once again, you can pull any look off. So don’t be afraid to wear round, button, hoops, studs, dangles (although make sure they aren’t to long), but take a chance and wear triangular shapes–they are really flattering!
–Round: 
Necklaces: Your goal and desire is to slim the face, so to give the look of dimension you want long necklaces. It is best to stay away from chokers and even big, thick beads near the neck that add a thickness to your throat. So a tip for those of us with round faces, look for anything that adds length!!
Earrings: Anything long that draws attention down instead of around is very flattering to a girl with a round face. A drop earring looks incredible, as do rectangles and squares!
–Square/Rectangle: 
Necklaces: Opposite of the round face, a rectangle wants to add width to take away from her length, so she wants to stick with shorter and thicker necklaces…lots of chokers.
Earrings: A good drop earring compliments a square face, while a button style looks best on a rectangular face.
-Heart: 
Necklaces: Well, many say chokers look best because it softens the sharp angle of the chin. Many times, if you add double or triple layers it adds width around your neck which balances the thinness and angles of the chin.
Earrings: The best look for a girl with a heart-shape face is something that is wider at the bottom because once again that will balance out that chin…something like a teardrop, upside down triangle, or even a button look perfect.
