The Classic Elegance and the Metro are RFID protected.
We have made the purses so that you can have a case on them, as you will be taking your phone in and out of the purse, and it will need to be protected. Of course it will depend on the size of case you have on your phone and the purse that you purchase, but most normal size cases on a phone fit inside the purse.
Depends on the purse. I have seen some fit in teh Classic Elegance and the Metro with an otter box on it, but of course if you have the largest phone and the largest otterbox, you might have a problem.
