Not to knock the designers at all, but I'll just say I spent alot of time and money buying designer stuff, before i discovered the magic of some of the niche stuff.
Of my designer stuff here's what I've found the most pleasing to women: YSL M7, Rive Gauche PH, Michael for Men, Chanel Allure, DKNY Men, Hanae Mori, Extreme Polo Sport, Cuiron, Amen, Mugler Cologne, Dreamer.
Of the more niche stuff. Passage D'Enfer has an unbelievable effect on women. I think what i like about the niche stuff, is this: They don't smell as much like something you went to a store and bought, they smell like an aura that you radiate, they seem more like part of you. And this comes off like confidence to women. And this is why i think CdG is my favorite house, because their scents really give you an air of mystery and artistic confidence. I'm not proud of this, but I got a bottle of Jaisalmer the other day and the first night I wore it out, I got some late night action. Anything from the Incense series would be great in this regard.
I think it took me a while to get into niche because of the limited ability and the notion of instant gratification. I didn't want to wait for something to be shipped. i wanted to be able to run to the store anytime money was burning a hole in my pocket, and as a result I ended up with a lot of designer stuff that just bores me.
Plus the designer stuff is constructed to grab you right away, but the downside is this feature makes them immediately cloying and after a short while you can get sick of them. Niche stuff by contrast may seem tame at first sometimes, but once you wear it enough, you can see how much better it wears and how the right scent pulls rather than repels. Also when you wear stuff like the CdGs, you'll smell like nobody else, and girls will find you really unique and like a rebel freethinker.
As for Bulgari Aqua- its not bad, but its a Aqua di Gio clone.
