Today is Smile Day, the perfect day to celebrate being modified to perfection. For those who have a smiley piercing, this is a particularly fun mini holiday, as the whole point of smile day is, well, to smile. Piercings of the upper lip frenulum are most often worn with circular jewelry, so the more the wearer smiles, the more this sweet semi-secret piercing gets shown off to the world. And for very special occasions, an extra dose of brilliant color is the perfect way to show off this fun and interesting piercing. Talk about a bright idea.
