This is one of those perfumes that extends across all age groups. It is sweet, exotic, light, fresh with staying power. It is modern and, yes, a bit ethereal but sensual too. It reminds me oh so much of the ORIGINAL Poision by Dior (which has since been reformulated and smells nothing like the original). Alien smells ‘pure’ and not synthetic. I have allergies and this one is fine. This is an all season fragrance and is neither too warm nor too cool. I’m reviewing based on a sample received. I may just have to request this one!
