I'm in a very small minority, but as much as I have enjoyed Givenchy, Reserve Privee just doesn't work for me. I'm frustrated that I'm unable to pinpoint which note doesn't work for me, but I've worn it a couple of times, and it's just not for me.

@Craig Stevenson When I sampled this one, I didn't get a chance to try the original. Sometime I'll have to try it, as well.

@Edward Mooney I don't know pour monsieur , but as an older guy, I think the classic fragrances suit me very well.

That's the one Le Male I own as well. I really love it. Enjoy!

@Dave Anderson That's the way I'm leaning, as well. Between a growing collection and a robust box of decants, I don't use much from any one bottle each season. So I will choose a 50ml bottle to afford more fragrances whenever there's an appreciable difference in price. If I actually do use the whole 50 ml bottle and still love it, I would probably replace it with a 100 ml bottle. Yes, I pay more per ml overall, but I prioritize variety over price-per-ml, so that works for me. (Especially because I'm also doing something similar for my partner.) If I were going to build a must-own collection of just 8-12 bottles, I would go for the big bottle each time.

I used it to analyze my current bottles and identify holes in my collection. I have to say it's been pretty accurate so far.
