The ultimate designer perfume?

My husband loves stuff like Coco Mademoiselle and Miss Dior on me, so I decided to add one of those classic feminine designer perfumes to my collection. I'm totally not knowledgeable in this category though; besides my Coco Mad decant I haven't bought anything like this since the og Dior Addict.

Right now CM is #1 on the list (I want to sample the Intense too). But since I've kept decants of this around for many years I'm interested in moving on to something else. Are there other suggestions for what I should look into?
