The way you dressing up all in a harmony with the place you are going, this is one of the rules of the stylish society that we all know.
Cologne is similar, imho. Depending on where you go, what you wear and what age group you are targeting it really is important what you chose.

The only recommendation I can make that's universal to any brand of cologne u use, don't over use it --- p l e a s e!! you don't want to pass through a group and make them all smell you. you want to use your cologne as the sniper shot when you are whispering to your girlfriend or a lady's ear
