If it's body spray/mist, I usually spray it ALL over my body (since the scent never lasts long). But with perfume I spray my wrists, behind my ears, back of my neck (the fellas like that spot ) and my cleavage. I tend not to spray my throat (front of the neck?) because I'll get annoyed with the smell quickly.
On my arms , neck , shirt , and sometime my chest , all depends on what I am wearing , sometimes people can smell me from a mile away because I go a little over board with the perfume
