The best perfume combinations usually pair one dominant scent with one supporting layer. Vanilla with amber feels warm and smooth. Oud with rose feels rich and luxurious. Citrus with woods creates a clean and elegant daily profile.
Simple rule
Choose one fragrance as the main character and one as the supporting layer. If both scents are loud, reduce sprays. If both are soft, use a stronger base note such as amber, woods or musk.
