Sublime Vanille follows a very simple formula. There is vanilla, and there is some lemon citrus and bergamot. That's it. Creed wanted to make a vanilla fragrance, but one that was safe, not too rich and cloying. And they did that successfully. It's extremely versatile. Men can wear this well, though it is unisex leaning slightly to the feminine side. The strong point of this fragrance is that it is a vanilla fragrance that is perfectly fit for the summer as it is fall.
As for what this smells like, it smells similar, and I mean very similar, to Midnight In Paris. Of course, it's a much better version of Midnight In Paris. It's fresher, smoother, uses higher quality ingredients, and has all the sweetness without the powder. But this scent is linear and it doesn't develop in any meaningful way. It's the exact same thing, from start, to finish. Which is good for those who want consistency, though the opening is not so great that I'd want to preserve it throughout.
Flaws aside, this is by no means a bad or negative fragrance at all. It is good, bordering the better side of average. It's simple and simplistic, not very creative and not very original either. When you compare it to other Creed's, it just doesn't stand up in quality or creative direction. And this is not just a regular Creed, this on their "exclusive" line. For, $225 (1 oz) and $640 (8.4 oz), I simply cannot recommend this. If you want to buy a vanilla fragrance at a niche price, just go with Tom Ford's Tobacco Vanille.
That said, while this isn't worth buying, if you do happen to acquire it somehow, it still is worth wearing. I will still wear the rest of this decant, but I won't buy any more.
If you're a big fan of Midnight In Paris, you might be happy to know there is a fragrance that smells almost exactly like it, but better in every aspect (if you can stomach the price). Personally, if I wanted a lemon-vanilla fragrance, I'd go for Hanae Mori instead. And I wish the only reason for that was because Hanae Mori is 95% cheaper.
