The right earrings can be the finishing touch that turns an ordinary ensemble into the envy of every woman in the room. But the wrong earring can be a painful experience for both your ear and your fashion sense.

The good news is that knowing the difference between the right earrings and the wrong ones is easier than it seems. Here are some common sense guidelines to help you get started:

1. Choose a Great Design

Like other types of jewelry, earrings come in a wide variety of shapes and styles. Although the style of your earrings will often be determined by the occasion, you shouldn't be afraid to branch out and try new designs. Experiment with an assortment of styles until you find the ones that are right for you.

2. Metals to Consider

Earrings can be comprised of a variety of precious and non-precious metals including gold, silver, and nickel-based alloys. When choosing earrings, it is important to note that certain metals have been known to cause allergic reactions in some people. This is especially true of nickel-based metals, small amounts of which are found in stainless steel. If metal allergies are a problem for you, then you'll probably want to look for hypo-allergenic earrings made of either titanium or niobium.

3. Matching Earrings to You

Color is another important consideration in earring selection. A nicely colored earring should complement your eyes and facial complexion as well as your outfit. Experiment with an assortment of colors until you find ones that draw out your complexion and go well with the colors that dominate your wardrobe. Remember: You buy earrings to match your outfit, not outfits to match your earrings!

4. Gem or No Gem

The decision to wear an earring with a gemstone is largely based on occasion and personal preference. Small gemstones add an interesting sparkle for everyday wear, while larger gemstones should be reserved for special occasions. Another factor to consider is cost. For genuine gems, the bigger the stone, the bigger the price tag.

5. Is Bigger Better

When it comes to earrings, size matters. A good earring takes into consideration not only the size of the ear, but also the hair and face. If the earrings are too large they will draw undue attention to themselves and detract from your overall appearance. If they are too small, they will not be seen.

6. Remember to Check Weight

The weight of your earring makes a big difference in both comfort and appearance. The droop of an overweight earring looks bad and can be potentially harmful to the ear if it leads to ripping or tearing of the lobe.

7. Hoops and Dangles

In addition to size and weight, the length of the earring also needs to be considered. Although a longer earring can add a touch of elegance, it can also hinder your movement and easily become more of a problem than it's worth. When trying on longer earrings, make sure you can easily move your head from side to side without catching the earring on your collar or shoulder.
