Ooooops! I´m twice your age, and I really like what you call young perfumes... And they suits me well, perhaps because I am still girlish, witch is nice to be in my age!
Two more grown-up perfumes I like are Cristobal by Balenciaga and Prada. Both are orientals, and have some authority. Cristobal is very feminin and Prada is fresh, still a little heavy. They are not the most grown-up frags on the market, perhaps they can suit you.
My eldest daugter, in your age, is very, very fond of Gucci EdP II. It´s a girlish perfume, but with great personality.
And there is Lovely by Sarah Jessica Parker, perfect for work, as it is not in anybodys face, and yet really fun. It´s not so very young, either!
