Givenchy's Dahlia Divin Le Nectar is absolute class in a bottle. Despite being discontinued (a travesty, say fans), it's a beautifully blended, warm floral that smells expensive and draws compliments. Some find it a bit too sweet and powdery, others complain about performance, but the consensus is overwhelmingly positive.

This one's a proper head-scratcher and polarising as they come. Many find Opus V lacks imagination, smells of bleach, or is just 'meh', but its few devotees hail it as a masterpiece of creamy orris and subtle woods. Definitely not a blind buy.
