Can I wear mixed earrings?

I have so many single earrings that have lost mates. I only have my ears pierced once - can I wear different earrings in each ear or would that look really weird? I would wear complementary ones, like a pearl hoop and a single pearl, things like that, not totally different earrings. Please give me your opinion. I do NOT want any more piercings in my ears! Thank you.
