If the tiara is not for a fancy, formal outfit (such as a prom, wedding, or other big event), choose a tiara that will be the focal point of the outfit. Make sure that your tiara matches your jewelry, and does not clash. For example, if your jewelry is silver with diamonds, pick a tiara that is also silver with diamonds.
If you have a heart-shaped face, choose a tiara with a V-shaped peak. This will create the illusion of a longer face. If you have a long face, go for something with little or no height that extends evenly across the top of your head. Avoid tall or pointy tiaras. If you have an oval face, you can get away with most shapes. You might want to avoid styles with peaks at the center, however, as this can make your face appear longer. If you have a round face, go for tiaras that have a bit of height or a peak. These can make your face appear longer. Avoid rounded tiaras.
Make sure that the tiara is not too tight, or you will get a headache later on.
Consider adding some waves or a soft curl to your hair. This will give your hairstyle some movement and grace. For a more casual look, consider going with a simple floral tiara instead.
Give a ponytail some volume by teasing the hair at the crown of your hair into a slight bump.
On the other hand, many girls choose to wear a tiara on their 16th and 21st birthdays in order to stand out and feel more special.
