Thank you! The SA did warn me they don't sit 100% flush on the ear. The very top "lifts" up a little off the ear, for lack of a better word. It's not really visible from the front, and I don't feel it unless I touch them. It may depend on your ear lobes how much they lift. It doesn't bother me.
They do stay in place, as long as the backs fit snugly.
The SA also said they can be worn as dangles, if you switch the earring to the opposite ear. I'l get an ear shot of that tomorrow.
Wearing them as dangles sounds great, too! Maybe I'll give them another try.
