She literally looks like she is cosplaying Tank Girl.
Ripped jeans, a tshirt and a sleeveless vest and boots, wow normal clothes that anyone can wear. I'm halfway there right now in ripped jeans and a tank top. I know it's been said a million times but these people have the most conservative ideas on gender roles.
It's seeming more like a constant cosplay LARP.
They want to be a character they have invented. Probably a character they created for role playing games in many cases. (A troon I know is literally doing that openly. "Her" character is a persona she LARPs in across many different games and settings. She is also not unknown to show up to parties as her persona.)
Many of these Pooners have an idea based on Yaoi and their romantic ideal of a guy.
In previous generations, similar ideas of men would be based on Mills and Boon or Hallmark novels and films and would be more an romanticized idea of a man that the socially awkward woman would wish to meet and marry, rather than become.
In both cases they don't really have much extensive interaction with men in reality, expecting maybe fathers and brothers, or other male close relatives.
Or, possibly a gay/nice guy/nerdy best friend.
While I am not saying men are either uber geeks, queer, or ultra macho, what I am saying is most ordinary men are a varying blend of geeky and macho.
For instance, football fans who are insanely knowledgeable about players, scores, results, stats and other things which if the same kind of focus was placed on trains or Star Trek, they would be considered geeks.
Conversely, there are the occasional math and science thick lenses wearing nerd, who turns out to be an accomplished boxer or rugby player and thinks sci fi and fantasy are ridiculous.
The idealization of girls is certainly done by Troons, especially the AGPs, who skin walk a personally constructed idealised version of a girl they know.
They develop the fantasy further by creating a videogame/RPG character who is this idea.
Helen Joyce posited a theory about older men who Troon out after having lived a double life as a transvestite, considering their transvestite identity to be a real person, and to them, more real than their wives and children.
The gender identity thing is just a massive fantasy, a legitimization of this fantasy by pseudo or misunderstood science and medicine, followed by a politicization of it, followed by an attempt to turn it into a civil rights struggle by hijacking an established but tenuously related one.
