At the risk of making everyone self conscious about their bodies, when you're looking to read a person, to tell if they're CD (or TS) what tell-tale signs do you look for? Which ones jump out at you?
Personally, I look for big hands/feet, or broad shoulders. Of course, these aren't very good, because plenty of people of both sexes have them, and it can be ahard to tell what's "big" sometimes. On the other hand, most other things can be surgeried, hormoned, or disguised away. An MtF could always have a tracheal shave for the adam's apple, or wear a padded panty for narrow hips, or have estrogen round out the angles. But there's nothing anyone can do about big hands and feet, other than make them irrelevant by nailing everything else.
