Gianni Campagna - Zagara It mixes orange blossom with white flowers and honey so it should be sweet
i Profumi di Firenze - Arancio di Sicilia. It's a Sicilian Orange, very fresh and is an eau de parfum so long lasting. I've got a new sealed bottle for sale lol as my mother ended up with two for her birthday in September.
Keiko Mecheri - Orange Sanguine and Maître Parfumeur et Gantier - Jardin du Néroli (I think they're more blood orange)
Lorenzo Villoresi - Dilmun has orange blossom and other notes
Mazzolari - Fleurs d'Oranger has orange blossom, jasmine, flowers and musk
Micallef - Floral is orange blossom, raspberry and fig
Penhaligon's - Anthology Collection - Orange Blossom 1976 is worth checking out
