Through the years, she was sometimes open about her feelings, so it is possible to roughly reconstruct her tought processes through the years.
At least since being a teen, she has some form of body dysmorphic disorder. Especially in her eartly Tik Toks she talks about parts of her body she doesn't like the way they are. Because of that, her self esteem was low. That is likely the reason why in her earlier content she wore more revealing stuff and also why she made an OF. Through the years, she matured somewhat, got rid of her OF and stoped releasing stuff that is explicitly sexy. Her newest song is about self image issues, so she has't overcome that body issue fully, but i think it is safe to say that she is dealing a lot better with it, or that it isn't as severe as it once was.
Her current train of thought towards what she is posting is, that she is posting unasuming pictures, and only because of her big boobs they gather sexual attention. If she would't have big boobs, her pics wouldn't seem lewd in any way. At the same time she refuses to dress like a nun so to speak, and wants to wear pretty stuff regardless of her size. So that is where we are right now. She wants to leave her past with OF and the lewd stuff behind, while doing here music and using her popularity to promote her stuff. She sure enjoys the positive feedback she gets when posting the occasional bikini pic, but she doesn't want to do anything that is conciously lewd.
