I agree with some of the guys here...take a woman with you. I went with my friend Ken and we were in the store for like a hour. We smelled, sprayed, waved it around, smelled it again, walked away and finally purchased Kenneth Cole Black for him.
The one thing I look for in a cologne is if it smells like alcohol when you first spray it. Most of the time they don't small good when you wear them.
One of my favorites is Polo Blue.
I love the smell of a good cologne makes me a little moist.
