I came across this handy tip via the Lifehacker Blog.  I am kind of clueless about fragrance so this is probably old news to all.
Drop for drop, colognes and perfumes are some of the most expensive liquids around, and yet they can wear off before you step out your door. The TipNut blog suggests that moisturizing the area where you'll apply the strong stuff—like with petroleum jelly or any non-scented moisturizer—helps lock in its strength longer than spraying onto dry skin. Combine that with another hint that pulse points are a scent distributor, and your eau de toilette just might earn its keep for the night.

While I am on the subject of fragrance I posted several weeks ago that I bought some some bath and body products at Ulta.  So far I have only been using the Citrus Cream Body Lotion.  It IS very orange-y but not orange blossoms rather more like ORANGE LIFESAVERS.  That isn't necessarily a bad thing since it makes me feel like a kid in grade school when I put it on in the morning.  I haven't used the Orange Mimosa Shower Creme yet but it too is not a particularly sophisticated scent.  What the heck neither of these items were expensive and they are sort of bargain aromatherapy.
