I havnt read 10 pages of posts to see if my favorites were already posted.... but here they are.
On a date, or if im going to be around attractive women i wear Ferrari Black or Polo sport. I do get good responses but at the same time i enjoy the smell, i think i smell good, which gives me a little extra confidence.
If i dont want to waste my good cologne on a regular outing to the grocery store, or at work where i dont have many opportunities for approaches, i wear la coste. Its moderatly cheap and is a very subtle nice smelling scent.
