I made a fantasy zerg/tyranid/ect style race except they weren't rapacious and genocidey and just wanted to chill, so they needed to design ambassadors that wouldn't freak out the neighboring human country. But how would they do this? Well obviously they'd have to be pleasing for humans to look at, but the details are important. A woman wouldn't get enough respect no matter how beautiful, or rather the suspicion of witchcraft at work might actually make it worse. And a towering adonis of a man would be too intimidating and send the wrong message (this race places great importance on the form of one's body when judging them, since for them their body is built with meaning and purpose, in fact they might overthink it sometimes). So essentially they needed something pretty to look at, male in order to garner respect, and feminine/harmless-looking enough that they won't be seen as intimidating.
And so the crazy biomonster nation has cute femboy ambassadors they send to other kingdoms. Well, their skin and hair colors are kind of weird and things slither under their skin sometimes, but they are trying their best damnit!
