Spritz two solid pumps into the air, then wave the blotter lightly into the dissipating fragrance in the air. After you do this, narrow it down to the two or three you generally like best, then you can move onto testing them on yourself.
If you know what family of aromas you tend to enjoy--i.e. woodsy, oriental, spicy, citrusy, etc.--you can generally figure out which fragrances you'll probably fancy by looking at the colours. This is not a universal truth at all, but as a general guideline in a sometimes intimidating or overwhelming area like the fragrance counter, knowing which ones you might like can be a good start to finding your signature scent. Blue or frosty white tends to indicate cool and fresh while green probably will mean cedar and black or dark brown will be leathery or musky. Again, not true 100% of the time, but it can be a good place to start.
Use coffee beans in-between testing on the blotters.
Test your favourite 2 or 3 on one of your pulse points--your wrists. A pulse point is essentially a warmer spot on your body, you can tell where they are because your heartbeat is felt more easily there and your blood vessels are near. Why do you do this? It essentially keeps refreshing your fragrance all day long, as if you've applied and reapplied it. It will have a nice, strong, lasting presence, but it will not be overwhelming, and that's the goal here. Again, you're not going to get the full aroma if you spray it directly onto your wrist. Spritz a few full pumps a good 9 to 11 inches away from your wrist, and kind of move it around gently to "catch" the particles that are floating away.
Don't spray your clothes. That's a big no-no. Instead, we're going to again concentrate on the pulse points, but not just the wrists this time. The crooks of your elbows are also a good place to spritz lightly, as well as the base of your throat, and up on your neck jaw line behind your ears.
