Serge Lutens is not necessarily known for "clean" scents (but you should try this line- especially Daim Blonde!). Florals are traditional for the bride - I would suggest Creed's Spring Flower, a lovely fresh floral with a hint of fruit, Bulgari's Rose Essentielle (dewy rose, violet and woods) or Sarah Jessica Parker's Lovely. For a budget price, try Carolina by Carolina Herrera (strawberry leaf, cardamom, orange, rose, pepper, clean musk and light wood).
Bulgari's Eau de The Verte might be a unusual choice - the Basenotes directory compares it to CKOne, but I think it's much more sophisticated. Enjoy your sniffing !
