Maybe my mother is not yours. But the ones I have given to my mother lately (with great success) are Armani White, Versace Chrystal Noir, and Calvin Klein Euphoria Blossom. Not very upscale but nice smelling.
But I am looking forward even more to this year´s birthday since I have bought her a sampler pack from The Perfumed Court: Niche and Classic Beginner Sampler Pack (Perfume Posse Blog picks) - 21 samples.
Of course I have tried all of them (very very little ) and I am thinking of buying her a bottle of Jean Patou 1000 or a decant of Chanel Cuir de Russie for Christmas... Just to have it laying around for myself.
