My point was that certain traits are highlighted and exaggerated for a reason, broad shoulders in men and women were seen as commanding. This meant that their attire exaggerated this in their courts, IIRC it was common for visiting Kings or Queens to wear less dramatic attire when the purpose was alliance seeking and wore more dramatic attire when the purpose was to be threatening.

Modern CEO's and Presidents don't display this type of showmanship in their attire, however take a look at Presidential portraits and portraits of the First Ladies, they still strike the artificial poses displaying broad shoulders.

It would take you an exceptionally long time to find a successful political figure in a posture that doesn't make them look commanding. They're actually trained to hold certain postures and frequently have personal gym instructors to help improve posture, this got leaked about President Sarkozy in France as he was mildly overweight, causing him to change to more comfortable postures in long meetings and speeches, etc.

People take posture to be quite trivial, but the amount of time spent on it by our societies elite really shows how important it is. I can't remember where I read it, but it can supposedly boost approval ratings by ~10% for presidents.
