As to how long lasting it is? I tried it on one wrist last night when shopping, (it completely drowned out the Ralph Lauren Blue I tried on my other wrist!) had a scented bath before going to bed, and now 14 hours later I can still faintly smell it! And I normally have fragrance fade fast on me because my skin is so dry!
I haven't tried Demeter's Sugar Cookie, but as all Demeter fragrances are colognes, (to keep them affordable) and thus less concentrated they tend not to last as long as an eau de toilette like Pink Sugar.
