As a trans woman, this idea of young girls younger than me appearing seemingly flawless has also led to some at times intense gender dysphoria in me, genuinely believing that I can't even be considered a girl because girls are supposed to look feminine and to be feminine you have to be flawlessly attractive, right? You gotta have the right face and hair and legs and thighs and shoulders, don't forget about all that makeup you'll require and boom only now can you be considered feminine and beautiful. Don't have any of those things? You can hardly call yourself a "girl"
It's these subliminal messages that have been ingrained in our heads in day-to-day life that lead to such thoughts, not just in me but in young girls in general, trans or not!
I cam imagine I am not the only trans girl that has felt like this, but I think that this has much to do with the.... intense ferishization of young girls and young girls convincing themselves that they have to be flawlessly attractive and look like actual grown up women.... it's really, really messed up
