The Perfume that lasts long

I was a member of one of known cosmetics companies. I tested almost all of their perfume products but only one caught my taste. The scent was mild yet luring. But the problem was, it won't last long and I have to put on every now and then. Until such time that my aunt in law gave me a perfume which is a product of the most well-known brand all over the world. It is not only catching my taste but its scent will last even within forty eight hours. You may guess what perfume is it because I won't tell you its brand and its name.
