I agree with Angel, a tiny tiny tiny bit goes a very long way. Just to be safe I use it only in winter and make sure I have plenty of time to let it settle before I go out.
With most of my other perfumes I do a spray and naked walk through, then touch whatever is left on the sprayer to my wrists.
My favorites right now are Issey Miyake's Drop of Cloud and Theirry Mugler's Innocent Illusion. I save my Armani Code, Issey Miyake and Angel for winter.
