As you can imagine, everybody has his or her own must haves.
So let's say the classics. It is hard to get more classic than Shalimar, so yes to Shalimar (the original one, not the various flankers); it is a vanillic, resiny oriental, though, quite different from the ones you seems to like, which are more big florals with fruity overtones. In that category, a classic is Fracas by Piguet (big, buttery tuberose). Or, to remain within Guerlain classics, Nahema, a huge rose jam. In niche, something by Lutens, who specializes in big, saturated fruity-woody scents, such as for instance Feminite du bois or Bois de violette.
