Never buy a perfume because it smells nice on someone else !
My friends and I went through the stage of getting together and getting ready to go out and on one such occasion I had forgotten to bring scent so my friend said to raid hers, I have always loved her taste in fragrance. I made my selection and thought no more about it until we jumped into a cab and my friend asked which perfume I'd gone for as she didn't recognise it. It turn out we were both wearing the same thing but it smelled very different on each of us, on my friend it was the exact same fragrance as it smelled in the bottle but on my skin it had developed a more floral scent
I later spoke to my mother about it and found out that my Grandfather couldn't wear citrus based after shave as his skin seem to absorb it !
