I imagined the wife as a fashionable, but not too trendy, woman who enjoys a decent silk scarf and grainy leather handbag when she sees them, and has a mildly sweet tooth in what concerns fragrances. Without making Ronald jump through hoops I suggested the following rich-smelling and quite classy fumes.
First of all since she's already familiar with the prolific Thierry Mugler brand, why not upgrade to the truly gorgeous Thierry Mugler Alien Essence Absolue? It retains the jasmine and amber scent of the original Alien, and is not miles away in concept, but adds a soft luxurious undercurrent of resinous myrrh, orris and a leathery scent impression which nudges it into true luxury; the difference between an Hermes purse and a Coach one...
Next came the following recommendations I made.
Staying in the Mugler universe, there's Mirroir des Envies; still sweetish but classy and with a jasmine-y heart. Quite uncommon too!
Sarrasins perfume by Serge Lutens is jasmine scent heaven. The scarcity is also a plus in this instance. Not to mention it even has a soft fruity hint via osmanthus.
Exploring the jasmine and white floral theme with a cocoa-vanilla overlay: Christian Dior Pure Poison Elixir. Less common than the original Pure Poison and a tad softer too.
On the subject of white chocolate (and the patchouli hinted at by her like for Miss Dior Cherie), I suggest the perennial classy favorite Chanel Les Exclusifs Coromandel. Drop dead gorgeous!
If a fruitchouli is considered, then Badgley Mischka eau de parfum is a good option, classier than most in the genre and not well known in order to smell herself coming and going.
Finally, for daytime, because a girl needs a clean floral sometimes, I went off the beaten track and suggested the ethereal Le Cheuvrefeuille by Annick Goutal. She might also like Gelsomino Nobile by Acqua di Parma.
What do you think? What would you suggest he surprises her with?
