The two worst features a (mtf) troon can have.

Height. Being tall will make you stand out like a sore thumb. In most places around the globe, women over 6”0 are incredibly rare. Every masculine trait you have will be amplified x10. Tall cis women will sometimes be mistaken for a troon if they have slightly masculine facial features.

Larger lower face than the middle face. This one is brutal. This permanently puts you in the clocky/hon category. With a brow bone you can at least get a haircut or style your eyebrows in such a way that it de emphasizes it (unless it’s comically humongous). But that chin and jawline ? Forget about it.

If you have both, then uhhhh…. my condolences, I guess?
