I have heard two contradictory pieces of advice from generally qualified people. I struggling to understand what takes priority.

  1. Stand with a good posture, exuding and aura of confidence and power that "poeticises my presence" and commands the room

  2. Mirror the girls posture, which might not be proper posture—insecure and unconfident. Feminine posture applies to. But my mirroring her, you get all the purported benefits that come with mirroring, forging a stronger connection with her.

In the event both are paradoxically true, what's the key nuance?
