As time goes by, the fashion and trends have changed. They always bring out new things to the market and society.
Back in 80's, you won't see men wearing earrings (or maybe yes...but you can count it with your fingers), but today you won't never see or meet men wearing earrings. Men love earrings as much as women. Earrings are a fashion icon for both men and women.
So go girls...you deserve the best ^^
