First of all; I have to say that I don't really have a #1 fragrance because it depends on the day on my mood, but there are sure some fragrances that I can not miss. And one of them is YSL Kouros. It may soudn odd, but when I first met with Kouros I did not like it. I did not hate it, but I found it odd. That time I was young and at that time I was used the fragrances like Azzaro, Jovan Musk, Jovan Sexappeal, CD Jules, Denim, CD Eau Savage, Aramis and Kouros was way different than these fragrances. My father had bought it as a new fragrance and he liked it and my mother was fond it too, but it did not mean much to me. I guess it is like getting to know wine, beer or cigar you have to let your experience grow in it. I can still remember my first beer and wine. I did not like them, but now I know what wine and beer is. Now I know better which one I like and which one I don't. It was the same with Kouros. First I did not like it, but on one day I had to go to a night party which was important for me because I was just getting now a nice girl and I would like to influence her also with a nice fragrance. I had a smell in my mind that I did not know what it was. I was getting crazy to find it out, but I had no clue. I was looking at the fragrance shops and departmen stores but I was never getting near to Kouros, because I haven't liked it and never thought that I would like it. Just one day before the party I was again in one of the fragrance shops and a guy beside me had asked for kouros and he had sprayed it. The moment I had scent in my nostrils I was looking around. He was the only customer in the shop who was trying a fragrance. I asked him what it was and he told me that it is Kouros. I though: No way, you'r kiddding me! I gave it a try and that's it! Since then I always use Kouros in special occasions and time to time as a casual fragrance when I feel like to smell it on me, but I have to admit that it is not a fragrance that you can use daily. If you want to use it daily or in a closed place then you have to a be carefull with how much you use, but if it is an open-air occasion, then no need for fear.
