This is really more related to a new found discovery then being ready for the potty so much. I know a lot of toddlers that go through this. Don't put diapers on her or if you do, put them on backwards. If you do the pullups, put something hard for her to pull down over it, like feety jammies or a one piece something. It is normal, unfortunately a nasty phase to go through. Praise her if she does it in the bathroom and goes, however be stern with her it is not to come off in her bedroom!!!!! I hate to say this but a number of friends that I have used duct tape to help eliminate issues. Sounds bad but duct tape during naps stopped the phase really quickly! Good luck.
