The language of perfume

For the first time in so many years I don't like to think, I ran out of perfume and had to buy some myself! I have worn Obsession as my signature perfume since it was first brought out - but it doesn't smell the same to me anymore. So I was on a hunt to find something similar to the original perfume I fell in love with all those years ago. Google is my friend - and I found out that the top notes were Orange Blossom, Tuberose and Bergamot, and that it had good sillage... Sillage??? It actually means it leaves a fragrant trail - I misread it as silage... Guess I've been listening to The Archers too much!!!
