Right now I'm really digging on Groove by Carol's Daughter and Stella McCartney. My all time favorites are Dolce & Gabbana Light Blue, Esclat D'Arpege by Lanvin and Angel by Thierry Mugler.
My all time favorite is CK1 becuase it is unisex and the smell is classic and will never go out of style. I also love Amazing Grace by Philosophy, and also all of Britney Spears various frangrances.
