I don't know why people are so snobby about celeb scents. They are not made by the actual celebrities, they are made by renowned noses or respected scent and flavour brands. The celebrity just fronts the campaign.
SJP Lovely is superb as is the diffusion collection: Endless, Twilight and Dawn.
Another good one is JLo Deseo, Jessica Simpson Fancy Nights, and Hilary Duff With Love which smells like Tropical Woods.
To be honest, a big brand name is no guarantee of quality. If it smells good wear it.
The advantage to celeb scents is that they are made by prolific noses, yet are often cheaper. Granted a lot of them are synthetic fruity florals, but smell it before writing it off!
(having said all that, I will never, ever try or buy anything by the Kardashians!)
