For a more casual look, individuals can wear different styles of earrings. Many of the cheap styles for instance, colored, love heart shaped or even simple shapes can be a great compliment to your face and to the clothes you are wearing day or night.
Try looking and wearing earrings that are studded and perhaps that are of neutral colors. This will ensure that no matter what you choose to wear for the day, whether it is your favorite jeans or a summer dress, that the earrings will always look like they match and not out of place. This can create the ultimate casual look for your style and add more flavor to what you wear day in and day out.
