The composition plays by all of the rules of a girly fragrance—its sugary sweetness is comprised of fruity notes and vanilla, its sheer base is laced with musk and amber, which bear little relationship to their animalic predecessors. Princess is a cocktail of pink fruits sweetened with vanilla and topped with a dollop of frosting.
The opening is simply more flowers, less pink fruits. It is a little citrus-y, a little green and a little sharp, and as advertised, smells first like watery-fresh orange blossom, then like watery-fresh rose-ish blended florals (the notes: green ivy, tangerine, water lily, orange flower petals, Moroccan rose, jasmine sambac, mimosa, apricot skin, amber, precious woods and musk).
While Flower Princess is quite different from Princess in the opening, after about 30 minutes, they're not so very far apart. Princess is a little more musky, Flower Princess a little more floral and fresh. There aren't any dramatic changes after that 30 minutes; both scents just get progressively weaker.
Vera Wang Flower Princess was developed by perfumer Harry Fremont, and is available in 30, 50 and 100 ml Eau de Toilette and in matching body products.
