There are tons of personalized jewelry options out there right now, but I like these by boe earrings especially for their simple design and versatility. Don't limit yourself to your initials, get weird with it: FU; AM; PM; NO. And if you have multiple piercings, the possibilities are even greater: WTF, OMG; LOL.
Sadly, with my standard lobes, I'll have to stick to a single pair. God, mom, why wouldn't you let me be cool?
