I cannot see teenage girls liking Egoiste for a second. Many will disagree with me, but I'm trying to help you.
This. Take it from someone who has a teenage daughter. The only one of these power-frags she likes is Escada Pour Homme.
If you're wearing it for yourself? Sure. You might find girls like this. Confidence and maturity appeal to girls. So if you, wearing your fragrance, feel confident and mature - even if they don't love the way you smell - it might help more than simply having a girl sniff the 1 Million, or Fierce fumes wafting off you before saying you smell nice. Very few women would consider a man viable simply because he smells nice.
No, more likely she'll ask you what you're wearing and then tell the guy she DOES like to buy it. Sorry if that sounds harsh but it's reality. Fragrance won't make that much difference.
Still I would, as this poster did, recommend Bleu de Chanel, Platinum Egoiste or even Allure Homme Sport. These are still very classy, mature scents and, just like egoiste, their quality is off the charts. The scent is more casual and compliment-friendly though, especially Bleu, plus the bottle is gorgeous.
That said there's many others. YSL's l'homme or l'Homme Libre for example.
I say hit up the Chanel counter at your local department store, and the YSL counter too. You'll find the SAs there better than those wandering the general fragrance area. They'll help you pick something or at the very least give you things to sample and you can make up your own mind. If you don't want to pay department store prices just tell them you need to think about it.
Don't go spend 100+ dollars on Egoiste, or anything else for that matter, because some stranger reviewing it said it's a PD or a lady-killer or whatever. Not even if a hundred of them say so.
