I've got two small hoops in my right earlobe & in my left ear a ring through my tragus and a leaf stud in the lobe. Added to that my ears are different shapes. Mismatched or what! They've never come out you know. I can't stand the thought of pushing them out LOL
I would probably wear those!! Actually, there wouldn't be any point as my hair is too long and covers my ears so you wouldn't see them but if you could I would!! I do wear mismatched earrings in that I have 2 piercings in one ear and 3 plus a cartilage piercing in the other!
I wear mismatched socks all the time - no, not disorganised, I bought them like that!! Company called United Oddsocks!
