Where to apply scent?
In general there are a few places on the body that are popular application spots for various reasons
chest: a more intimate place to apply perfume, it also works well if you have a very strong scent you want to tone down a little or if you want people to come closer to smell what you are wearing.
behind the knees: this is alo a good place to apply perfume if you don't want others to smell your scent too strongly. Also it is said that when you sit you can smell your scent rather well but it won't bother others so much. Very useful if you work in an office
your wrists: the idea is that these are warm places on your body that will waft the scent better.
behind the neck: gives good sillage, that means if you walk by someone you will leave a sort of scent trail
hair and clothing: hair and clothing are excellent places to apply perfume to if you want the scent to last longer. Just make sure it doesn't stain your clothes. Some people are worried the alcohol in perfume will damage hair and you may want to take this into consideration.
