What IS a 'traditional dress?' I'm sure I don't have any!
I'm not sure if this question, or the answers, make the process more complicated. It is rarely as simple as 'just take the shot' though, and learning to be still, to be aware of surroundings and to forget the ceaseless distraction of Self is essential to hunting well. Ortega i Gasset's quote about being alert comes to mind.
I started out shooting without a goal of stillness prior to the shot. Monty pointed out that successful hunting, for him, involved not projecting his intention with his attention to the animal - because the animal can sense the intention. We had many conversations about sheilding the intention, and finally about not permitting it to surface in to consciousness until the arrow was released. It is a disconnecting in order to concentrate, to make the process come from muscle memory rather than cognition, and in order to avoid making a connection with the animal that will send the message for it to run.
After that I began examining ways that I could do it, and practice it, both while hunting and elsewhere. The adrenaline response always comes after the arrow is long gone, and unlike some it is not a feeling I have ever really enjoyed, whether in a kayak on a river, or in the forest. It is trying to manipulate my own awareness and responses that provides the mystery I seem to never solve.
And one I don't mind puzzling over.
