I have bought Paisley for my girlfriend, who's been wearing it pretty much non-stop for the last month (and that's with immortal classics like Loulou by Cacharel and Shalimar in her wardrobe).
As far as notes are concerned, I think the advertised pyramid is pretty much spot-on - what's not necessarily clear by reading it, though, is the amazing aptness of the name: this *is* olfactory paisley. Every single time my GF sprayed it, I got a different vibe (after a while, I stopped asking her "is it Paisley?" because I just felt dumb): it smells just like the fabric pattern, with several different colors very close to each other, always intersecting and bisecting without ever quite mixing down to a dull gray-brown.
The end result is utterly fascinating and absolutely enticing - I wouldn't call it a classic just yet, but it's certainly one of the most interesting feminine (or possibly unisex, for the more adventurous) scents in the designer segment.
