LAVANILA Vanilla Blossom Perfume has a wonderful warm vanilla scent infused with natural orange blossom. It's absolutely wonderful. Fresh Sugar Lemon, Narcisco Rodriguez For Her, and Pucci Vivara are all my favorites. They all contain wonderful notes of Orange Blossom.
Jo Malone Orange Blossom is by far the best Orange blossom centric fragrance that i like. Prada has one but I cant seem to remember the name, its very pretty and the orange blossom is pretty dominant. And if I remember correctly Armani code also contains orrange blossom notes.
