I have tried to put clothes on her but she takes them straight off. What should I do?
On the chance this is a real post, I'll bite.
Yeah, that'll make it a ton worse. Trying to force at all will make it worse. Kids don't think like adults, so it's like telling somebody that likes drugs, don't do drugs.
With any kid or teen, talking is your best bet. Fewer words the better because they won't process a lot of words at once. If you sound like a dick or condescending, you're gonna have them fight back.
Make a rule. If they break it, so and so happens. It's not a punishment, it's just a way of life. Stick with it.
It's gonna bite you in the ass, so don't do it on a day you two have to leave the house.
"Put your clothes on in full. If you don't, you stay in your room. No toys, no screens, no fun. If you do put them on, well we are going to the park/grandmas/whatever it is, but you're a big girl and big girls wear clothes. If you can't be a big girl, you will stay in your room and enjoy no benefits of being a big girl. Make your decision. I don't care what you do as it has no effect on me. Your choices only affect you. While you think about that, I'm going to go plan the trip to the park/watch some show/play with toys."
Make it her choice. Her choices come with consequences. No anger. No forcing. Her choices have nothing to do with you, so you don't get to be upset.
Stick with it. It's going to piss you off the first few times because she will pick the room and throw a fit.
This way of doing things goes for any behaviour you need to fix.
