My husband bought eau de parfum spray from Chanel for me, and I really loved the fragrance. However, recently my sister bought eau de toilette from Chloe, and I found the fragrance magnificent. The only thing, which stroked my mind, was the difference in their prices. I want to know from some expert here whether there is a distinct difference in eau de parfum and eau de toilette. Moreover, I would really like to know which of the eau de parfum sprays is more concentrated, and lasts longer amid Chanel and Chloe. Can somebody please offer some valuable advice? Thanks.
