I'm also boring, but not necessarily by choice. I cannot wear anything but sterling or gold - my ears get infected otherwise. I've tried every possible type of surgical steel, protectors, etc., but anything that's not a pure metal (or close to a pure metal) makes my holes bleed. Even the cheap sterling silver that blended with other metals can cause a reaction. *bleah*
So I have a fairly limited assortment to choose from.
My standard pair of earrings that I wear every day is a pair of small silver hoops with a sort of chunky southwestern design cut into them. I also have several pairs of gold hoops in various sizes, and some stud earrings as well. I have one pair of Mikimoto pearl earrings that my DH got me to match my mother's pearls and I wear those on special occasions and I have one pair of sapphire and diamond earrings that match my engagement ring that DH bought me on our 5th anniversary - and I wear those every now and then as well when I'm dressing up.
Other than that, I'm a very boring earring person~!
