Topaze is a beautiful floral chypre, Occur is a soft aldehydic floral, and Timeless is a leathery chypre (my least favorite of the three but some people find a similarity to Miss Dior...which I suppose I can sort of see, but I doubt it would measure up in a side-by-side test.) Topaze and Occur are two of my favorites - I give them both 5-Stars, but some of that could be for nostalgia....not too much though. I really think they're beautiful and wear them often. I can't recall Sonnet, Moonwind and Charisma enough to say what they're like, but I do remember that I thought they were nice, too (it's been a long time since I've sniffed those.) Oh, Mesmerize is a soft and sweet oriental that reminds me very much of Samsara!
To tell the truth, I see so many disparaging remarks about Avon fragrances, but I just don't understand it. At worst some of their fragrances can be derivative, or maybe uninspiring, but I've yet to come across a real stinker - nothing offensive, ever. Oh, Ariane is another nice one, a soft and airy floral chypre.
