How long do Bath & Body Works perfumes and body sprays last once sprayed on to oneself?

I have noticed that they can last all day at work. I use the body spray and have sprayed in the morning and still smelled it later in the day. It may depend on the scent...some are stronger than others. I love the Japanese Cherry Blossom and know personally that it will last a while. I usually spray it in my hair, front/chest area and inside wrists. It may not be strong and but the scent is still there. Hope this helps.
