Never in a million years would have thought of this particular combo, so I wouldn't have a clue what to tell you. (But then, that said, who would have ever thought that I'd be mixing Happy for Men with Gaultier2?) What's the combo like? And do you use the old formulation of Guerlain's Vetiver, or the new? I should think the new would be better due to its citrusy notes, while the old (which I myself like better) is so earthy and raw in comparison.
