Yes, the older version had better longevity and sillage and smelled a bit different. However, the new formulation is just fine to me, but if you are wanting more staying power try spraying your shirt a little. It will hold the frag longer than your skin.
I completely agree with you. The original Dior Fahrenheit lasted all day, and then some. It was a true powerhouse. Unfortunately however, as is the case with most Dior fragrances, the house reformulates the juice and you get a lighter version of the original. I find that Fahrenheit Absolute is closer to the original longevity of the original Fahrenheit formulation. I wish Dior would not do this, it is my favorite house.
Must be a bad sample that I received. I read that it was a strong fragrance in reformulation so I was surprised. I had an independent nose try to detect it on me after a few hours but it was faint at best.
Maybe it is all for the best. Over-applying Dior Fahrenheit can be difficult to pull off (unless you have the right look/attitude). Remember to avoid parking outside of elementary schools on heavy spray days.
