It's important to know that every scent or cologne smells different on every person. The way a scent takes to your body and your skin is a question of chemistry, and has to do with the chemical reaction between you and the particular fragrance. While your friend smells great in the latest Calvin Klein men's cologne, it could make you smell more like a gym locker.
With this in mind, it's always important to try cologne before purchasing it. Never assume that what smells good on everyone else will smell good on you. You would never buy a pair of shoes before trying them on, right? Well, the same goes for men's cologne
