I was given an earring too and it's fairly simple to remove whether creating a new or editing an existing profile.
Edit your profile, click on the accessories tab, click on earring none then immediately select ok and ignore the left or right ear option.
I think the confusion is that when you click earring none it then asks you to select what ear (left or right) and if you select an ear rather than just pressing ok the earring doesn't get removed, hopefully that's all clear and helps.
