And that's when authenticity comes into play. Confidence demonstrates being secure in yourself, being open and willing to demonstrate you're not okay or not sure shows your secure in not-being-secure in yourself.
People are put off by doubt in someones frame as it shows a weakness and potential problems not being self addressed.
If a girl rattles your feathers, be open and non-judgemental about that part of you and project that outwards, try meditating to get more present to the moment and be open about the fact you're in awe of her. It's a lot better than playing mental chess to try and get under the radar of a queen, when you feel like a pawn.
