No favorite smell but I do love the smell of certain flowers.
You should try smelling into a young blossom bud of magnolia flower. It is the small long tube type that is white. I have that at my work place so I plucked one and placed it in my shirt and for the whole day, I get a whiff of that good smell and depending on which direction the air is blowing.
Looks like this
As for fragrance, when it first came out, I used to sport aqua gio and boss hugo. I get good compliments with those. I would put some on my shirt and would freak nasty dance with a chick and would get her so close to me that my smell would be on her shirt. When she goes home with her friends later in the night, guess who she will be thinking of? check mate
