I think princess and disney princess can both be considered tropes. I get a lot of inspiration for very different types of women sprung board off the idea of a "princess" esque trope. Even though it's not specific, it's a very rich idea to draw from. And for Disney Princess as a trope, I tend to see it as the more "come my animal friends", cute, inspirational/idealistic/naive type.
Not a trope, but I have a character that was partially inspired from a random internet tweet "the feminine urge to commit arson".
