I might be little late to jump on the bandwagon but here I am totally in love with my new double sided earrings. The expression 'ear jacket' refers to simple studs with wraparound details. The wraparound accessory goes between the front and back or your earrings. The best part of my model is the fact that you can wear them in three different ways: You can wear the studs on their own or wear them with the wraparound either in front of your lobes or behind your lobes. Here is a picture of how I like to wear them.
I already know that I will wear the crap out of them. I just love the way they add some interest to daywear.
