...What a topic! I could write books about it!I presume AromiErotici labels those as designer brands that produce widely available, mostly mid-priced perfumes, whereas niche means the less widespread, often a bit experimental fragrances that usually but not necessarily have a higher price tag. I'm afraid I can only comment on men's and unisex fragrances.I think you can still find good classics in the mid-priced sector, such as some Guerlain fragrances. But the new releases are mostly boring and sometimes consist of ingredients that somehow smell cheap.At the German parfumo, I sometimes refer to some of those ingredients as scratchy - just like a cheap liquor that instead of being mild makes you cough and gives you a "scratchy" feeling in your throat. The nevertheless wonderful "Amber pour Homme" by Prada is an example for that.Occasionally, you come across a mid priced designer fragrance where the perfumer has made the best out of rather modest ingredients - this should also be respected. A few musky Hugo Boss fragrances should be mentioned as an example: "Boss Bottled Night" and also "Boss in Motion Edition White".Some designer brand issues from the last two years follow a very puristic, woody style - and they seem to be the follow-up of that now less popular sport fragrance trend. These fragrances may not be too experimental, instead they focus more or less obvious on tart woods: Almost all DSquared fragrances belong to that group, as well as i.e. Bvlgari Man and Michalsky Homme. I like that style!I think it is still worth to keep track of what is happening in the mid priced sector. I am always pleased and surprised when I find a new release that is really good, because one would not expect it!What we should worry about is what is happening with the so called niche sector. In Germany, we lately got the first chain stores (Apropos Concept Stores) that focus on the so called niche perfumes. Niche is currently becoming big business. Usually, so called niche brands issue 6 or more perfumes at once - all with the same package design. It seems to be more attractive for customers, when they see a respectable row of equal-looking perfume bottles on the shelf. Perfume shops become neat and tidy - chaotic-looking shops that still have their shelves packed with the full variety are obviously less popular. Last year, the most famous german perfume shop (Schnitzler, Düsseldorf) was re-designed in that way. People would travel to Düsseldorf because at Schnitzler's you could get simply "all". Now, they have thrown out a good percentage of their brands.The problem with those issues of complete lines is that you do not very often find really excellent and outstanding perfumes among them: Byredo, Krigler, By Kilian, Penhaligon's, Huitième Art, Tom Ford, Serge Lutens and others. Some other so called niche brands try to make the customers believe that their high price tags are an indicator of exceptional quality: Amouage, Bond No.9.Those true niche brands that usually do not release more than one or two excellent perfumes per year get completely out of focus: Divine, Hors Là Monde, Social Creatures, Humiecki & Graef, XPEC, Gentleman, Gravel, Czech & Speake, Nobile 1942, Sisley, Maître Parfumeur et Gantier, Annick Goutal, Ulrich Lang, Piazzini di Portofino, Aqaba - and presumably many others.I think you can smell if the perfumer was allowed the time necessary to create an outstanding perfume. Not every perfumer seems to be so priviledged as Jean-Paul Guerlain who took more that ten years between his absolutely gorgeous releases of "Chamade Homme" and "Arsène Lupin".
