This is a no brainer...cologne or aftershave should always be used in moderation!
Cheap stuff always smells cheap!
It should not be used like an air freshner!

use enough that if someone gets close to you then they may get a nice lite fragerance from you.
and PLEASE NEVER use it in place of a shower to cover up Body Odor!
Use the right one and the ladies will tell you right away that you smell nice and don't be surprise to find out that they want to get to know you better.
Women seem to like guys that smell nice are well groomed and dress the same way. Fresh and sharp!!
