I suggest trying Jo Malone Vetyver. It is a simple and very nice treatment of vetiver, neither too grassy, too soapy, or too earthy. Just right IMO.
If you can try Givenchy Vetiver, I like it better than Guerlain. They are similar, but I find Guerlain a little too heavy and soapy. Givenchy has a fresh lemony note that keeps it lively.
I think vetiver is an excellent note to explore. It can be done in so many different styles.
