I think there is no rule where to spray your favorite perfume. But maybe there is a better way to put on a fragrance.
People say, behind your ears, on your wrist, neck, hair, and so on. (Into the Gloss website describes more places, it is funny)
Then, I came across this Youtube video. Nearly at the end of it, she says where to spray your favorite perfume.
Since then, I follow the way she does.
So, enjoy watching and figure out where to spray! ( Video will start from there )
