I noticed that my girlfriend sprays her expensive perfume that I bought her into the air and then walks through the mist. When I first saw this, I thought she was wasting it. She explained that it's a subtle fragrance that catches your attention, and that's what makes it sexy.
The heavy set women that you smell reeking of perfume are ones that slather on gobs of it to cover their body odor.
Just a ps...guys use too much cologne and it drives women crazy.
