@sun@arcana I do not reference celebrities when it comes to passability tbh, but I get what you are saying. This is what I actually mean as indicators:
adams apple
hairlines
hands and feet, head size and other dimorphic traits like shoulder width and hips
bad fashion sense calls attention very quickly more than any of the above
having obvious injections or fillers in your ass that are in no way naturally proportional and proceeding to lie about it (it was so bad another trans mutual even said it was liess)
male dominated hobbies such as programming, a lot of the time (the stereotype is painfully true don't come for me lol)
