Women have worn them for thousands of years. They come in styles from cute to elegant to hard core. But the type of earrings you choose to wear could spell success or disaster. So here are some rules to accessorize by.By face shapeLong face: If you have a long face and narrow features, long earrings will just make it look even longer. Instead, balance it out with some short, round earrings.Round face: If you have a rounder face (about as wide as it is long), then round studs or hoops may just make you look pudgy. Choose long, dangly earrings to elongate your face.Heart face: If you have a wide forehead and pointy chin, balance it out with long, teardrop shapes—a smaller, upside-down version of your face shape will fill in the empty space at your jaw line.By hairstyleFormal up do: A pinned-up hairstyle with chandelier earrings will draw attention to your face and make your neck look long and elegant. Perfect for dances, formal dinners and symphony orchestras.Casual up do: For day-to-day wear, you don’t want to look like you spent hours in front of the mirror (even if you do). A twist-and-clip hairstyle with short studs or hoops can give you a finished look without looking overdone.Hair down: Long hair will catch on most long earrings. You’ll have to stop whatever you’re doing to pull hairs out of your jewelry. Awkward. Choose short, simple studs instead.By occasionSports: This should be a no-brainer – but sports and dangling earrings don’t mix! Small studs will preserve your feminine look while you get your game on (or, for a laugh, wear small hoops; they whistle when you run).Babysitting: If you’ve ever held a baby, you know they go straight for the shiny stuff. Large hoops make perfect (and painful) handles for their tiny fingers! So if you’re hanging out with small children, wear small earrings.Job interview: Unless you’re interviewing to work at a fashion magazine, it’s probably safest to go with small, conservative studs.myjewelrycenter.com
