First off, you should check the site reviews.. there are some really good assessments of the fragrances.
I would consider Terre D'Hermes a pretty safe buy and one that is rather distinct in its smell. I get the citrus at the beginning of the fragrance but it dissipates fairly quickly and the cedar in the fragrance shines through. It's interesting though.. I spoke to a friend of mine who says that the citrus stays pretty prominent on him so I'm sure it has a lot to do with skin chemistry...
Another aspect of Terre that is widely talked about on here is the presence of a very mineral'like note that blends in a very balanced way with the other accords. It's a very good quality scent... and I actually find it hard to describe. It's versatile too.. although it shines best in warmer weather..it would not be out of place worn at other times of the year..
Besides, if it isnt to your tastes, you could swap it on here in seconds... Take a chance.. hopefully you'll be pleasantly surprised. One of the frags that I was hooked on on first sniff and that just gets better over time.
