That is very interesting!! I love both scents but I don't see the similarity.
I find Blenheim Bouquet to be a somewhat astringent, cool lemon-pine. I really enjoy it.
Whereas I find LV Uomo to be a superb vetiver scent. Vetiver can come in many configurations, from heavy and soapy to really really earthy. In my opinion, LV Uomo gets it just right. It is a comfortable and comforting grassy sort of vetiver, a soft cushion of lovely smells.
But let's see what others think...
