Well, I have said this before and some agreed, some did not. I find Sacrebleu from PdN to be similar. Not banana-ey and stuff, but in that vein. It's also been recently discontinued. And it's harder to find now, too.
I cannot think of anything mainstream that is even close to Sicily, that's for sure.
Well, Van Cleef has that sort of vanilla-ice-cream, light-Oriental drydown, and also the vague plastic note, but it's so galbanum bitter on top.
But I did see Sicily widely available on ebay, and it was not exorbitant. Best just stock up..
