There were a few threads in the past about how to apply perfume, and as imagined, tastes vary a lot. The elbow is an excellent place to apply perfume (unlike the wrist), as are most other body parts. The cotton ball is also an excellent method - but there's an older method with cotton balls, especially for expensive extraits: apply perfume on a cotton ball and then put the cotton ball in your cleavage. The cotton keeps the perfume much longer than the skin.
I agree that the walk through method is a waste. It was thought for very strong frags, or for people who wanted a quieter whiff.
